My filter has a shut off, if you look close you can see the one on the right it keeps the water from syphoning back after you disconnect it. I am going to put a inline ball valve between the UV and the spray bar in the tank so I can service the UV.

First of all the canister filters I suggested have to be cleaned out every 3 months, the ones I have do not get dirty on the outside, and after 3 years they still look new! HOB'S have a function but if your dealing with only a few tanks you need to go with a canister. The set up on a 304B is, top basket is bio balls or ceramic rings, next is bio balls or ceramic rings next is a carbon or if you don't like carbon a medium sponge, and the bottom lair is a course sponge. I'm starting to reduce the amount of tanks I run because I'm getting to old. Until 2 months ago I was running 7 Fluval FX6's, 22 sunsun 304B's and 28 sunsun 603B's, on 50 tanks, If I can run that many tanks and filters at 69 years old, I think you can run a 40 and a 10. I have been in the hobby since 1969, 33 years of it as a professional, If you do as I say and stop believing all the horse pucky on the web you'll be OK.View attachment 458904 View attachment 458905 View attachment 458906 View attachment 458907 View attachment 458908 View attachment 458909
For the 40 gallon get a sunsun 304B. Buy the one without the media, and cut your own sponges, and buy a higher grade ceramic rings.
and for you 10 gallon, get the 603b. It comes with a good set of sponges.
Thank you. I use purigen in my HOB, can I put these in the canister filters? I buy the prepackaged 100 ml bags.
For the most part anything you put in an HOB will go into a canister, just in larger quantities. Canisters hold a lot more media.
Changing water in 50 tanks must be quite a chore, it takes me over an hour to do 3. By they way your tanks look great.First of all the canister filters I suggested have to be cleaned out every 3 months, the ones I have do not get dirty on the outside, and after 3 years they still look new!

I use a BIG PUMP and a garden hose!I have 2 from the Tidal I have kept in the AuaClear 70s pending buying a filter for the 10, then I have the two AC70 ones that are currently running, so yeah 4. Plus 2 pads in my betta tanks that I just have in there for forever.
you'll do ok with putting some purigen in a bag and putting it before the ceramic rings next to the sponge. If you cut your own sponges, the ones I recommended will last for years. Also if you want to spice up your canister, get some red and blue duct tape and stripe the can, you can call it "the all American made in China canister"!
I cannot wait. My order shipped already and is guaranteed to be here by Friday. Much cheaper than I thought it would be and got 2 canisters, one for 10 gallon and one for 40. Let's just hope my old, blonde, dumb butt can figure out how to install it.
Letsfish 77 huh? Amazing. Good for you.
Okay, calling all canister gods.
I have it installed. I think. It makes a whooshing sound. I have checked all connections, checked the levels of media, everything seems even, level. The cover is on.
What else can I check?
This thing is heavy when filled and so far I have it on the floor until I can stop the swooshing sound. Can low water level cause it? The hoses and intakes are bit demented right now because I have not moved it into place yet.
This.Sometimes that sound is trapped air, you can tilt the filter to one side or the other to expel the air and usually that will fix it.
Wow, You got them running, good for you. As said the swooshing sound is trapped air, the essayist way to clear the air out is the oval button on the top of the canister. Push it up and down 6 to 8 times and then hold it down until the noise goes away. It will always work better if the filter is well below the tank surface level, but I have run them even with the tank surface before and it will work except that you have to use the button every time you hear the swooshing sound.
fissh Yep, I did it. LOL. It is pretty much silent now. For this filter, there is no way for me to run it below the level of the tank. It is hugish, and tank is on a dresser in a corner, and nowhere else to put it, so would have to be run in front of the dresser if I put it below the level of the tank and those ugly green tubes would be an eyesore. It is still not pretty but maybe one day I will get rid of the dresser and buy a stand with an underneath to put the filter in.
So far it is working great. It cleared up cloudy water in 24 hours from messing with setting it up. At first I had the input/output switched and just kept pumping it over and over again, pushing huge air bubbles into the water and stirring everything up. I have not had to clean it out yet, so we will see how that goes first time.
Thanks so much for giving me such detailed information allowing me to buy one and figure it out.
I hate to admit it but I'm lazy and hate to clean filters. If you came into my fish store I would tell you to clean it every 3 mounts, but I don't clean mine for at least 4 months or more, depending on what the tank looks like. So I guess what I'm saying is you should play it safe and do it at 3 months.You should be good for a month at least before you need to do anything with the filter. I way over filter my tanks so I can get away with cleaning the filters every couple of months.

According to the specs on this filter, I am way overfiltered too, no? My tank is 40G, and the Sun Sun is for up to 200 gallons and processes 525 GPH.

I used two marineland 360 on my 125 they worked well. They also make a 160 model that's good for 30g.


Just a suggestion...go ahead and run double cartridges or extra pads in your HOB now so that you have seeded material to put in your new canister when you do get it.
I ran a fluval 206 on a 20 gallon high.. it's good for up to 45 gallons.. when I upped to my 55 gallon I bought a second one to run in conjunction with the one I had I liked the first one so much.
Easy to use, easy to maintain. Practically silent. You'll never go back to HOB again.

I think I got my first 206 on sale for $89.. the second one, 3 years later was $139, but was advertised, same store, online for $119 so they game me that price.The fluval is slightly higher the budget but it is a contender. Have you found any cons? Also the marine land caught my eye from the other guy along with the sunsun hw303b

The only con is possibility of leaking. So keep it in a container.. you'll notice the water level in your tank drop before the container fills. I had one with a slow leak and I simply returned it and took the next one off the shelf. It worked great.
In all, I've have 2 fluvals, and aside from the one that leaked a little water when I first turned it in, you hardly know it's even running.
They work well no real complaints other than I don't like cleaning them out but that with all filters like that.I don’t mind a filter rated for a bigger tank day like 55-75g( hopefully upgrade tank in the future lol) I saw marineland made a couple in my price range. No complaints?

Also you need to remember to lube the gasket seal every cleaning or over time it will break down and let water out of the canister
Part of the problem is the canister is at the same level as your tank. Intake for canister filters works of siphon, so they are more efficient with the filter mounted below the tank.
Not that good. Watch here.True. But I guess I wanted to make a good buy/choice. But how about a
