Heater That Works In Direct Area Of Ac?

So, my new pea puffer tank. Everything I read says to keep their water in the range of 77 to 82.

I bought a brand new DaToo 50 W heater, and waited the 30 mins before plugging it in to acclimate it. No matter where I put the dial, I cannot get the water above 77.

So, I ordered a brand new Aqueon 50 W heater, put it in Saturday after waiting the 30 minutes. Again, no matter where I put the dial, cannot get the water to go above 76ish.

So, I put back the DaToo heater with the Aqueon heater, and it is now 77.

I am afraid to put the dials up too high. I have them both on 80, which is where I would like to keep the temperature in this tank. It feels ice cold to me.

Is it my air conditioning. I have the vents shooting away from the tank but I cannot move the tank or the AC.

So now I guess looking for an accurate dial/temperature heater that works and will heat my water to 80 degrees.

Any ideas? Is there any heater accurate to what you set the dial for?

 

I'd say with ambient temp set cold/cool the 50w is struggling keep water temp up I'd be looking at a 100w

Okay, will look for a 100W. Thanks.

 

Heating an aquarium is a combination of how much of a change in temperature is desired, the amount of water in the tank, and how many watts the heater can crank out. Undersized and the tank never warms up, but oversized and the heater turns on and off so much that it burns out too quickly.

Most people only need 10 or so degrees above room temperature and can get away with a lower watt heater that provides between 2 and 5 watts per gallon. Personally, I am often asking my heaters to do 20 degrees, and have found I need at least 10 watts per gallon to make that happen.

Well, it is 10 gallons. I want it to heat to 80. My room gets pretty chilly I must admit, so I just bought 100 W heater. See what happens, be here tomorrow.

My 40-g has a 200W I believe and it keeps it stable at 80, 81. I have 2 betta tanks that are in the same area as the puffer tank, and I never ever have to even play with their heaters, and they are the same Aqueon ones I had just bought for the puffer tank, but I do not remember the wattage of them. They may be 100 but they have been in the tank so long I do not remember where/when I got them and the wattage. I looked at my order history at Amazon, Walmart, Chewy and Big Al's and cannot find where I bought 2 of these at the same time, so know.

My pest snail puffer feeder tank is struggling too. It is 3 gallons and cannot get it over 78ish, same 50W heater, and they are across room from AC. In past week bought 6 different heaters.

Hopefully the 100W keeps up.

 

What is the ambient temp in front of the tanks from the ac naturally will be colder in front a 50w struggling heat a 3 gallon hmm

Before you get the 100w let's work out that then we can work out how many watts the heater needs to heat over ambient temp

I was confident in the 100w but after seeing the 50w struggle on 3 gal

Seems like my house a igloo in summer lol

 

So the new heater works much better, right now it shows it is 79 degrees in there, but I had my AC on blasting all day while I slept. So, when I turn it down because it blows right on me while I work, the temp goes to 80, sometimes 81. So apparently, it was the wattage trying to fight the AC.
