I'm setting up a 5.5 gal betta tank. I live in PA. The temp of my house will range from 60-90 degrees in a year. 25 or 50w for this heater?

Get the 50W version. My tank is 5 gal and I was recommended 50W's and it works perfectly :)

I'm keeping 5.5 gallons of fluid at 85 degrees in a 50 degree garage . I do have a coat wrapped around it but it's keeping it at temp . 50 watt

I heat a 400 sq ft cabin with this heater and I have it hooked up to a 100 gal permanent propane tank. That said, I probably wouldn't use anything less than a 5 gal. tank.

NO...it will get way too hot!! I had this in my 2.6 G Fluval and raised the temp to 86. MAYBE you could try the 5 watt but better to go with a little betta heater made for that size.

I've had a Betta Tank for 2 years and this thermometer has worked great so far. Between 50 and 90 degrees. I keep my Betta at 76 to 80 and it stays within 1 degree all the time. You would need some moister to keep the thermometer sticked to the tank however. A great tool anyway.

I have used 3 Tempa 20s to replace other standard water heaters in my apt. complex units. #1, I would not consider a 50 gal water heater as needing a supplement. #2 the Tempra 20 is all you need for a bathroom tub or shower. I am in Wisconsin which is too cold for a 20. and yet they seem to work fine (28s are recommended for this cold climate). You may decide later to forget the 50 gal water heater. Hope this helps. Yes, I would recommend you make this purchase. [If you live in a hard water area, be sure to install a whole house water filter (about $40) ahead of the Tempra or the salts will damage the Tempra flow mechn.]

There's multiple sizes selectable here. I prefer yo run two undersized heaters so if the thermostat goes bad i in one it won't cook the fish. For a 39 gallon I'd think you'd want like two 100w heaters.

For a 125 gal. tank ,you should get the 300 watt, especially if its a glass tank . you can probably get by with the 250 watt size . these heaters are the best made, and keep the temperature near perfect. I don't recommend using two smaller heaters ,one is easier to set and maintain.

Hello RaeRae, You answer is not so simple. The capacity of a heater not only depends on the heater itself, but the original temperature of the medium. Even though this is rated for a larger tank than you are asking about, if the place the tank will be in much colder than average is may be a good choice. If your water starts at 65 degrees, and you want it at 78, this may work for you. If you start at 72, this may get the water hotter than you want. Another aspect to consider is how much water movement you have in your tank. The more water movement, the better the heat will be distributed, and the water will be closer to the thermo's temp setting. I agree with JR, I have not seen any for that small of a size. You could look at reptile heating accessories that afix to the outside of the tank, it would be a hack though.

No. On average, a heated tank needs about 5 watts of heat per gallon, but bettas are tropical so 7.5 should be fine.

Kellie is correct. I have a 40 gal tank for my RES and I try to keep the temp at 76. I bought the 150W model an it just spends 95% of its time shut off. I am planning on downgrading to a 100 W so that it can spend 90% of its time shut off and still hold the right temp. The other benefit is that the lower wattage ones are shorter -- my turtle loves to squeeze in and pry the heater off the wall so a shorter one will be more difficult.

Any heater designed for <5 gallon tanks will fit in the same chamber designated for the water pump. Having said that, if the overall ambient temperature of the room you're placing the tank in averages around 70 degrees, I wouldn't even bother with a heater because you may experience unwanted algae growth...

I just leave the heater plugged in. I have a gallon tank and it stays at the right temp range of 80 to 85 degrees. I don't think this heater would be good for a smaller tank, it would get too hot. I hope this helped. This heater is great... bought it over a year ago and it's still working.

The 10 watt is too much for your tank. I had mine in a 3 gal and it was too warm.

I was not able to get it to heat a 20 gal or a 10 gal, so I have it in a 5 gal tank and it still doesn't heat to the level it states it will. I put it in a smaller tank with some fish that don't have to have the water temperature to be maintained at over 75, so it's working find in that situation. I suggest getting a submersible heater that allows you to adjust the heat to the temperature you want, that's what I now have in both of my larger tanks now and I was very disappointed when this one wouldn't/couldn't keep up with at least a 10 gal tank. Good Luck!

A 40 Gallon should have a 200 watt heater... it's 5 watts per gallon is the normal requirement
2073920
100watt would be plenty. I have one in my 50gal tank and it easily keeps the tank at 78 degrees. Just as my 300watt keeps my 120gal at the same temp without difficulty. Hope this helps!

This listing is for a 50 watt heater. The standard recommendation is about 3 watts per gallon.
