Better to get 1 or 2 Heaters

I am planning to get the Eheim jasper heater for my 65 gallon tank I would like to know is it best to get one big wattage heater or two medium wattage heaters to heat my tank

 

I have the 300W Finnex HPG on my 55. Little different footprint than your 65 but has worked great for the past month or so i've had it in there. I had the Eheim 200W and its a sonofagun to calibrate and don't feel it was pulling its weight and keeping the temp stable. But that's just my experience with it. Possibly operator error but doubtful. The other plus side of the Finnex is you can adjust the temp with a button on the cord rather than reaching in and turning knobs.I think 1 of these heaters will keep your tank to a comfortable temp.

 

Here is the table to help with what size individual heater you need. Delta T is the difference from the lowest ambient room temperature in the room to your desired tank temperature. Always get a heater larger than you think you need.

I can’t get the file to open but from the last time I saw one of these I think I needed. 250-300 w

I looked online on amazon and it has bad reviews only 3/5 stars people say it has bad suction cups and the display show the wrong number I am kind of on the fence with this heater

It's worked well for me so far. It's like pretty much like everything else in existence there will be good and bad reviews. Go with what you feel is going to work for you I was just giving my opinion on the Finnex

I appreciate your opinion on this heater I will do a little more digging with each heater to see witch one will suit me best thanks

 

I am having trouble finding a good heater online my goal is to buy on from amazon my price range is anything 60 or bellow I have looked at different heaters like the fluval e 300w heater, aqueon pro heater,aqueon adjustable pro aquarium heater,the finnex hpg 300 w heater and the Eheim jager. I can’t find anything that has good reviews and fits my budget. My tank is a 65 gallon tank thanks for the advice in advance

 

I recently changed the heater in my 55 from an Eheim 200W ( tricky to calibrate ime) to the Finnex hpg and like the finnex a lot more seeing you can raise and lower the temp on the wire instead of on the heater itself

 

Aquatop. The new digital one doesn't look as nice, but it's a copy of the finnex design. The temp adjustment is on the wire so there is literally no electronics in the water aside from the heating element coils. Should be a forever design unless they made the coils slightly too thin in order to fail after 5 years.

I looked on amazon and some people say when you revive them they are not calibrated properly and amazon doesn’t have a warranty for that I looked online

Witch heater would that be ( witch model )

 

Did you want to do just one heater? I usually recommend two for redundancy.

I was told 1 300w heater should be fine for my 65 gallon tank because I have a lot of flow in the tank I have a fluval 306 and a Marineland 350 on my tank

AquaTop digital heater with external control.

 

I was watching a video about the viaaqua quartz glass submersible heater has anyone had experience with that heater it has a warranty witch is good because the finnex dosent so that’s why I’m not sure about getting it because if it breaks I can’t get a new one I have to spend 60 bucks and get a new one

Yes, one heater will be ok, but it's better to have two for redundancy/consistency. Let's pretend your tank is 6 feet long and you put one heater on one side, sure it'll eventually heat the whole tank, but the opposite side of the tank might actually be cooler than the rest. Solution? Add a second heater of the same size to the other side of the tank.

This heater is a little but out of my price range I live in Canada so price will vary any other recommendations

If anyone has a good heater recommendation that is under 60 CAD I would love to know I would like to order it some time this week

Good advice from nikm128. What you want to do is place the heater right next to the input of your filter. This way the heated water will be taken into the filter and distributed through the tank. I have a 300 watt that sits right next to the intake prefilter on my HOB.

 

Oh I didn't realize the CAD thing, especially with imports being what they are right now. Would 2 150 watts work in your situation? I believe I had a 200 do just fine for me when I had my 65 set up. I could be misremembering it though, it could have been one of my 300 watts.

But remember, heaters aren't additive, 2x 150 doesn't equal 1x 300, just more even heating to a lower temperature

Oh man. I am not getting into this bizarrely worded debate agreement about heaters again. 2x 150 watt heaters that can only heat to 90, won't heat to 180, but they do equal a 300 watt heater. A watt through 4 resistors is a watt through 4 resistors. Otherwise, running 2 300s and a 200 in my tank would only do as good as running a single 300 watt. I promise you a single 300 watt won't keep my tank at 90, but if I set all my heaters to 90, it will get there in a few hours and stay there.

Yeah two 150 would work. Yeah I forgot to put the CAD thing in my post

For the fish I’m keeping I can have the water from 75-80 my room temp is 71 so not to much to go my room is very humid to so probably more like 73-74 I have a lot of tanks

 

During my research. Heaters if needed are a very important piece of hardware. Everyone has their favorites. you get what you pay for.
I have Aqueon Pros in all my tanks (6). From a 50w up to 300w. And know quite a few members here use them. Set it and forget it "Easy".
My ambient room temps are around 70', I keep all of the tanks at 78'. I just started a 55 gallon Discus tank they need a temp of 84' so I have 2x (300w and 200w) redundancy is recommended for "Discus".

I did experience an issue last month with the first I purchasedt which was in use for 2 years. Their 'Customer Service" was good. Here is the review:

And here is their chart:


Good Luck on whichever you decide to use.

Now that we know your Delta T is less than 10 degrees, a 150 watt will be fine for your 65 gallon tank. Having 2 will add for temperature stability and redundancy in case one fails.
