Fluval Spec Spray Bar Mod (complete With Part Numbers)

[fishyAdventure]

Hello all,

Not sure if this is the right spot to post this mod, but hopefully this will help those in the future looking for an easy and cheap solution to the Fluval Spec tanks to control the flow/baffle it without sticking a sponge or any other eyesore to the filter.

After some serious Googling, I was able to scrape together a parts list for a very CLEAN and successful "spray bar" that fits the Fluval Spec 3/5 without any modification to the original pump or outputs. This worked out GREAT for my Betta.

Here is the final product (its not technically a spray bar the way we are using it, but its a spray bar for another kit zoomed sells):

The parts are from various zoomed kits, I was able to get this delivered to me for ~13 dollars. Just plug these part numbers into Google.

PTC-13 - 10/15 Spray Bar (rigid) with plastic plug 1 $3.50
PTC-11 - 10/15/30 Rubber Elbow 1 $1.50
PTC-46 - 30 Clear Plastic Plug 1 $1.00 (optional, got this as a just incase)
PTC-07 - 10/15 Suction Cup with Clip 1 $1.00 (Ended up not using this)
Subtotal: $7.00
Shipping: $6.65 via Priority Mail Flat Rate®
Payment method: Credit card (Square)
Total: $13.65

Instructions:

• The plastic spray bar is far too tall to do this unmodified, so simply grab a small hacksaw and just cut about 2 1/2 holes down, or to whatever length you see fit. I cut mine so that the end hovered above the sub-straight.
• Make sure you sand and de-bur the plastic and wash it out.
• Take the output nozzle and carefully remove it from the ball joint.
• Press the elbow to the ball joint nozzle for a secure fit.
• Press the elbow to the spray bar.
• Install and enjoy
• (Optional) - I ended up taking a matching drill bit and drilling through the existing holes as pilots to create a second row of holes behind the existing ones, my Betta wasn't happy with just the set of single holes.

My plants are also enjoying the better water circulation and the detritus and debris getting actually pushed up and into the lower/upper intakes for the filter.

Credit for the idea goes to a lost reddit thread that got me started with some of the out-dated part numbers. These are recent and confirmed as of 8/8/2018.

Share and enjoy!

GREAT mod fishyAdventure
The idea of generating better flow at all levels of the tank in the different layers of tank water is exactly what you need to maintain a healthy environment!
Nice share with all the parts!

 

[Tsukkomu]

thanks for this!!! this is exactly what I wanted. so excited.

hey just curious....so without drilling a 2nd set of holes in the spray bar the flow is too high for a betta? i'm curious what setting the flow on your pump is. i'm ordering the parts for this mod right now. i'd like to get away without having to drill a 2nd set of holes. but I can manage if that's the case.

currently I have my output baffled but the pump is on full blast. thanks so much.

 

[fishyAdventure]

I followed the wisdom of many reviewers of the tank and cut two holes in the return pipe to help circulate the water where the pump resides (this is where I placed my heater), so I have my pump set to high with this mod. I didnt try it on low. You can probably get away with it on low without a second set. Play around with it and give it a try!

 

[Tsukkomu]

Yes I have a couple of little holes I the tube as well. Works great! Okay I’m really excited about this mod. The prefilter sponge isn’t working for me. Thanks so much.

 

[THRESHER]

I'm a sucker for all DIY mods. Very well done and thanks for sharing!

 

[IceFyre]

That...is a great idea. I've thought of something similar on the pipe connecting the pump to the outlet at the top of the pipe, but just 1 hole about a 2mm wide, just enough to push the water down to the pump. But this is just what I need for my shrimps.

 

[FergusDaFish]

Ooo, neat! I have a big ol' white filter on my output to temper the water and it's ugly anything - and right at the front of my tank, too!

Might give this mod a try when I redo my guy's tank.

Did you put your pump on high or low with this mod?

 

[fishyAdventure]

I'm running it on high because I punched a few holes in the return line from the pump to circulate water better around the heater in the pump compartment (this was recommended almost everywhere online that I read for these tanks). So my pump runs on high with this mod, never attempted the low settings with this. Low setting with one set of holes may work out (I didn't attempt it, I just went straight to drilling a second set of holes).

Once you have this assembled experimentation is easy!

Please share your results after you get it assembled!

 

[FergusDaFish]

I just ordered the parts (shipping cost more than the parts did ) so I've decided that I'll redo his tank weekend after next so all the agitation and mayhem happens all at once rather than disturbing Fergus more than necessary.

That'll also give me another week to leach tannins from his driftwood and play around with his tank design.

I'll definitely let you know how it turned out.

Did my spray bar mod last night!

My tools:
Spray bar (Zoo Med PTC-13)
Elbow (Zoo Med PTC-11 - rubbery and a little flexible)
Plug (Zoo Med PTC-46 - Not necessary but nice to have in case; the spray bar comes with a plug)
Saw (I used an Xacto Precision Razor Saw and mitre box)
Power drill w/ 1/8" drill bit
Sand Paper (I used 220 grit)

The length of the spray bar is definitely too tall as shipped to fit without being sawn to size. As the OP noted, a good length to trI'm the bar down to is between the 2nd and 3rd hole down from the top.

Here is where I trimmed my bar to - I trimmed off the top two holes. See the last photo for where this put the length of my bar.

I did a test fit of the elbow to the filter output and confirmed that you do need to fit the elbow to the ball joint of the spray nozzle that comes with the Fluval Spec V. Take the spray nozzle off (the middle piece) and the elbow fits snugly over the large ring just past the ball joint on the bottom piece here.

Here is the bar installed. Like the OP, I drilled an extra line of holes in the spray bar and did several test fits to test the flow. For me, on the low setting of the filter pump, the flow was much too strong for Fergus with either one row of holes, and with two rows of holes at the pre-drilled size. (The pre-drilled holes are 5/64", or at least my 5/64" drill bit fit perfectly in those holes.) I expanded both rows of holes with my 1/8" bit, sanded them down and Fergus is much more happy.

The flow is strong enough to see some detritus being agitated but not so strong that Fergus is being blown around the tank like he was with just the pre-drilled one row of holes. With the two rows of 1/8" holes and the pump on low, Fergus is able to confidently swim around the tank, stop and float without fighting a current, and only gets a little blown around when he swims right up to one of the holes or when he swims along the bottom, front edge of the tank where the current created by the bar is strongest.

If you don't want to do the spray bar mod but need to baffle the filter output, you could do what I did in the first tank photo in this post and take the ball-joint nozzle off and stuff some sponge material into the output hole. It doesn't look terrible, and would look better than it does in mine if you use black material rather than white. I used white just because I had some on hand already.

Great mod!

 

[THRESHER]

Awesome job on the mod!

 

[Tsukkomu]

awesome. i'm waiting on my parts. opted for the cheap $3.18 first class shipping. how long was shipping time? I can't even find a place on their website to plug in my order number and check status.

with your two sets of holes, is one side facing the opposite end of the tank and the other directly behind facing the filter wall? and you have your pump on the lowest setting, with two sets of 1/8 inch?

 

[FergusDaFish]

I chose the cheapest shipping option and shipping was still more than the parts I purchased. :sigh:

If you looked down at my tank from the top, the length of the tank is oriented from 9 o'clock to 3 o'clock with the spray bar on the right with the holes angled at about 8 o'clock and 2 o'clock. Fergus likes to swim along the front of the tank so I didn't want the bar angled straight at him (9 o'clock) and have him fighting the strongest current the bar would create, and that angle would cause the back holes at 3 o'clock to just create a turbulent corner that served no purpose.

I also have three little holes cut into the tube on the filter-side to circulate water around the heater more but that doesn't seem to hugely impact the flow rate out of the bar, it's still pretty strong.

 

[Tsukkomu]

I was given multiple shipping options. First Class was $3.18. then Priority was $6.something and then UPS ground was about 12 and overnight was over $30. I chose first class and whoa - the parts got here in two days. just get the cheapest option anybody doing this mod.

I also chose to purchase the 30 clear bottom caps...I believe the number was 30. they did not send those. sure it came with the 1 cap the spray bar comes with...and now that i've gotten it in the mail I see it was not necessary to purchase the other caps. but I did pay $1 for it.

and now I am on the hunt for an 1/8" drill bit.

 

[FergusDaFish]

Home Depot is your friend.

Installing and removing the spray bar is really really easy so I'd encourage you to test out hole options to find what works for your tank before jumping straight to the larger drill holes. 1/8" holes worked for me but smaller holes worked for the OP. If you have a smaller drill bit already I'd start with that one and see if that will work for you.

amazing. just amazing. my tank was crystal clear before I installed the spray bar. immediately after installing it it turned into a whirlwind snoglobe situation!! the detritus from the bottom - crazy! within 15 minutes it was clearing out...making its way to the filter intake. by this morning it's back to crystal clear.

probably the biggest benefit besides detritus agitation....is heating. before, with my outflow baffled with a prefilter sponge...the bottom 1/3rd of my aquarium was always 2-4 degrees F cooler than the top. which really bothered me. now the entire aquarium is the exact same temperature. I feel a lot better about that.

I did not feel like going to Home Depot...to find a 1/8th drill bit. so I took a nail, attached it to a pair of vise grips....heated it on the stove and carefully melted a 2nd set of holes....haha. I look it cool, soaked it in dechlorinated water and sanded down the edges. I had to repeat this process a few times to get it right....I don't recommend this. it doesn't look as refined but it doesn't bother me. I have to repeat it one more time and resand as the flow is still a little too strong. my betta doesn't seem to mind but I can see him swimming at an angle right in the middle of the tank. he seems perfectly fine compared to last night but I am going to expand them.

this is a great mod! my tank is a consistent temperature. more detritus and waste is going into the filter. I feel like it's much cleaner. and yeah! this was a win win all the way around.

oh! I also positioned my spray bar holes at 8 and 2. I played around with several times. I first tried 8 and 2 and then a few more different positions. you are correct FergusDaFish, 8 & 2 position is the best position.

also I haven't installed the suction cup clip yet. but I believe I am going to...after I enlarge the holes once more and resand it.

thanks to everyone who blazed the trail!

oh, I also emailed ZooMed and let them know they forgot my 30 clear plastic plugs....that cost $1. I told them I wasn't upset but maybe someone else wouldn't be so nice if something was left out of their order. we'll see if they refund my card $1. =) I've actually never had something left out of an online order before.

wow! That's a pretty significant temperature difference in such a small tank! I've only noticed a 1-2 degree temperature increase in my tank but it makes me wonder if I move the thermometer around if I'd get temperature stratification like that...

 

[Tsukkomu]

Yes move your thermometer around. This is what I do. I’m using an analog thermometer for just basic monitoring. However I test twice a day using a high accuracy calibrated digital kitchen thermometer. I move it around. I drop it to the bottom. The temp has always varied with the prefilter sponge. Now it doesn’t.

 

[FergusDaFish]

I tried moving my thermometer around the tank and it read the same temp everywhere.

Mod is still going strong. I've noticed a little bit of stringy algae build up around the holes that doesn't easily scrub off with a toothbrush, and the bottom inside of the tube gathers a bit of crud but I've been rinsing it with WCs and it's still working like a charm!

mine is also working great. I as well have stringy algae on my spray bar. my snail cleans it off....he goes up and down and the water stream blows him all which way every way. it's cute.

also my temp is consistent now with the spray bar installed. i'm happy. I have a piece of filter felt in my filter....and the pump is on high. betta is very content.

 

[FergusDaFish]

Filter felt in your filter?

Tell me more.

 

[Tsukkomu]

Filter felt in your filter?

Tell me more.

they have 100 micron snd 50 micron. I got the 100 micron to make sure it didn't reduce so much flow. my tank is CRYSTAL CLEAR AMAZING!!!!!

it gets dirty fast. it removes SO MUCH from the water column. I just made a template and cut it to size. laid it in the spec filter. its a snug fit.

it comes in a gigantic square of fabric. see photos. have to change it once a week, every 10 days. I tried filter floss, polyfill...this works so much better.

It's $12.99. will last a long time. I HIGHLY recommend it. for me it was the missing link for my fish keeping experience.

 

[FergusDaFish]

Lol, I found your amazon review You seem very satisfied.

So if I'm understanding correctly, the filter felt is slowing the water to the pump and that's why you had to turn the pump up? Is your whole filter compartment filled with it or is it just a layer on top of the factory filter that comes with the tank?

 

[Tsukkomu]

Well yes it slowed it down but not considerably. My betta has become accustomed to high flow and doesn’t seem to mind...it is a noticeable cut back. On high it’s percectly fine. High may be too high for you. It is an excellent product. And yes when I get a good product I believe in I leave rave reviews a lol.

 

[fishyAdventure]

Wow, I haven't been on the forum in a week or so, but I am STOKED to see that its working well for you guys! That was also something that I didnt mention was that my temperature equalized across the tank, in fact I had to lower my heater a bit to get it where I wanted it. And I am also getting some algae build up near the holes, but I just use a pipe scrubber on my weekly change and its no problem.

I'm stoked to see everyone having great results on the Spec3 and 5!!!

Yes the thermostat battles were short and sweet once I installed the spray bar. It was like a whole new heating system had gone into the tank. But I figured it out.

I love it! I especially enjoy watching all of the snail poop to ‘snoglobe’ it’s way around and around the tank, eventually making it to the filter intake...the vast majority anyways.

Thanks for blazingthe trail.

Hi,
Do you think it would effect the tannins from the Indian almond leaves my spec v betta tank?

Hi,

I can't say for sure but I don't see why a mechanical filtration system would remove tannins from the water. I thought that was what carbon filters were for...

Super glad I stumbled across this thread. Unfortunately don't have the tools available to do the spray bar mod for my Spec V right now, but I certainly did just order some of that Filter Pad!

Currently using a pre-filter sponge to diffuse the flow and not loving it.

Super glad I stumbled across this thread. Unfortunately don't have the tools available to do the spray bar mod for my Spec V right now, but I certainly did just order some of that Filter Pad!

Currently using a pre-filter sponge to diffuse the flow and not loving it.

The filter felt is INCREDIBLE! I change it every 6-7 days. I’m the Spec V you can tell when it needs to be changed other than visually inspecting the filter felt. The chamber that houses the pump will go down considerably. It happens rather fast. Did you order the 100 micron or the 50 micron? I have the 100 and it ABSOLUTELY perfect! Everyone that has seen my aquarium has something along the lines of, ‘whoa. I’ve never seen a home aquarium that clear.’ It sparkles like diamonds. The one purchase of $12.99 will last a long long long time of only using for the spec. If you put a small amount of poly fill on top of the filter felt it’ll last you a bit longer than 6-7 days.

It definitely does cut the flow some. But I’m not sure if it would be enough without the spray bar mod. I haven’t tried it any other way.

I didn’t like the prefilter sponge either.

I didn’t have the right drill bit either. So all I used was a sharp knife and a nail, that heated on the stove (grasping with pliers) and melted a 2nd set of holes directly behind the first ones. I then used a sharp knife to cut the spray bar to length to fit inside the Spec V. And then used the point of that very sharp knife and simply twisted gently to enlarge the holes. Sand down with fine sand paper, which will make the surface no longer smooth and shiny. But I plan to paint it someday anyways. Once I find a suitable aquarium safe paint.

It took 3-4 times of gently enlarging the holes, then installing in the aquarium....wait and watch for betta to go all wonky in the current....pull it out. Repeat, etc. etc. until the size hole was perfect enough for my betta to be happy.

Tank no longer has a problem heating the bottom half of the aquarium due to horrible prefilter sponge. And so much more detritus and waste makes it into the filter.

I’m very happy. So is my betta. And I hope you enjoy the filter felt!!! Do the spray bar mod. I actually can not believe fluval doesn’t offer something like this. It’s far superior to the little jet they offer...maybe if you have stock that doesn’t mind pretty intense flow. But can not have the Spec v for a betta without modding the tank.

Cheers! I’m so excited for you try the filter felt.

I ordered the 100, arrives tomorrow.

I also ordered some privacy film intended for windows as a back drop. I just moved his tank against the wall recently and he was getting some reflections/shadows that were making him get a little angry. Threw a Hue LED lamp behind it and I have color control on my phone or Alexa. Saw someone else use this with just the frosted film as a backdrop and really loved it. Went back and forth on a bunch of different options and settled on this minI mosaic. Huge win with the already straight lines, cutting it to size was a breeze!

Great idea! I love it!!!! I have been wanting a Hue LED. My betta has never been bothered by his reflection. He stares longingly at it but does not get agitated. Bettas are all so different from one another and unique in their own distinct personalities. I love them.


Omg your tank looks amazing with that background and Hue light!!! Do you control it from your phone? That is a super creative idea!!! Also your tank looks great! You will be shocked when you add the filter felt. Give it 24-48 hours to really clear it....you’ll start noticing after about 4 hours though. Then just keep up with changing it to maintain water clarity.

 

[-Gravity-]

How quickly was your first change? I'll probably be putting it in right away, but then I will be out of state for 3 days.... 4 days too much to be away from it the first time around? My pump is one notch up from the lowest setting.

Yes, phone or Alexa voice control for the hue lights in the house. Usually it's just setting it to a preset scene of colors, on/off, or dI'm control.

I have to get one. So cool. It should last 6-7 days. My first lasted me 6 days and it was disgusting after that time.

Make sure you cut it 1/4” too wide. And 1/2” too long. That way it’ll kind of seal into the filter intake rectangular shape. I measured the intake, decided how much extra I wanted, then cut out a template. I use tweezers to poke it into place. Then check by looking through the other end into the filter intake to make sure there is no way for the water to be bypassing it.

also the directions say to rinse it well. So I rinse it really well. And then soak it in some water with a few drops of Seachem Prime. It doesn’t smell weird or anything. I never rinsed my polyfill. But I do rinse this because it clearly states to.

Thank you,my first tank, so I learn as I go...even though I am not too handy, probably going to try to make the spray bar, seems to be a good solution. Kind of getting tired of chasing snail poop with a turkey baster on daily basis...I wonder if it would help with the biofilm as well.

 

[FergusDaFish]

Ildiko The spray bar is a really really easy mod. It doesn't require many tools, especially if you don't do the second row of holes, and improves the circulation of water through the tank. I'll bet you could get away with only needing a new blade in an Xacto cutter to trI'm down the length of the tube until/unless you want to make further modifications.

RE: Snail poo + turkey baster

I've got pooping machines in my two snails and I have been unhappy with my cleaning method since my vac takes too much water out of the tank before I can get it satisfactorily cleaned so I tried a new method last week and it seems to be an improvement:

(1) Find a "dead" spot in your tank where the water doesn't circulate very efficiently or where detritus naturally tends to build up.
(2) Use your baster to blow water from the baster down at the substrate to stir up the detritus, aiming the baster so the jet of water pushes the detritus toward that dead spot. Experiment with how close you can get to the substrate without totally blowing it around: I have sand so I have to be gentle with the baster's pressure.
(3) Continue step (2) until most of the snail poo and other larger/heavier waste collects in that dead spot.
(4) Use your aquarium vacuum to suck it all out.

Because I have a large piece of driftwood in my tank the spray bar doesn't quite have the openness to create a strong current around the tank to push all the detritus to the filter so I came up with this new plan.

I also went to home depot last night and got two 1/2" PVC elbows and created a little vacuum filter so I can suck out debris but not remove water. Pretty handy for a mid-week clean if things start looking too cruddy.

Thanks for the tips, I am waiting for the parts to arrive and can jump on the spray bar project! Now that minI vacuum is interesting, could you include a photo please, if you get a chance...I live right behind Home Depot.

I followed the wisdom of many reviewers of the tank and cut two holes in the return pipe to help circulate the water where the pump resides (this is where I placed my heater), so I have my pump set to high with this mod. I didnt try it on low. You can probably get away with it on low without a second set. Play around with it and give it a try!

Hi,when you cut the holes on the return pipe did your pump become louder? I just punched holes on mine and it seems louder...kind of annoying to my betta, I noticed that he doesn't go near there anymore, even though that was his favorite spot to sleep.
I also did the spray bar mod today, but it's definitely the pump/return pipe,I checked.

 

[FergusDaFish]

Check that your pump was reinstalled well. I had my pump suddenly get really loud about a week after I bought the tank and way before I cut the holes in the tube but it got quiet again when I took it out and reinstalled it after a cleaning.

The holes shouldn't cause noise.

Thanks, so it's not the holes then. I tried every possible way to fit the damned thing. Getting a bit annoyed by it.Cleaned it out too. It also vibrates now,definitely more than before...

 

[FergusDaFish]

The return tube is soft so there is no mechanism that would take our vibrate to the point that it would create noise.

My guess is that it's something to do with your pump and how is installed that is either rattling against something else hard or some other hard component is rattling.

I even tried to put a rubber band on the pump,took it apart,etc. Contacted Fluval and they are sending a new pump,which is nice of them.
By the way in case someone punches too many holes on the tube, when they order the outlet nozzle from Fluval, it comes with a tube,just good to know. Othervise it's quite a mission to score one...
The new spray bar is working great,thanks for your idea!
