What is the range of gallons this heater will heat? I have a 2.5 gallon tank with one betta in it. In-home temperature is usually 64-72 degrees F.

Well, this would heat it. These are powerful heaters. I think 50 watts would be overkill (I am using it on my 8 gallon and I keep it pretty low). Plus, Jagers are larger heaters, not small at all. the 50w is 9" long and I believe it is the smallest. The 300w (I use them on my large systems) are about 20" long. For a 2.5 gallon I would probably get one of those small unbreakable heaters.

I believe this heater will be way too much for your small tank. I use this in winter only for 20 gal tank for a turtle. Hope this helps. Don't fry your fish!

The 50w model was designed for 6.6-15.8g aquariums. The full list of their heaters is listed here: https://www.eheim.com/resources/product//450/downloads/11/EHEIM_aquarium_heater_25_-_300_manual.pdf

Not sure. Mines in a 10. I think you want a lower wattage one. Check their website. They make a whole range of sizes.

To add to my previous comment... I finally had to put a 2nd heater in my Fluval Edge 6 gal tank in order to maintain the set temp. The room in which I have my aquarium is on the cooler side and is around 65 F... I really like the design of the Cobalt heater and the ease of setting the temp and am sure that it will work better in warmer months to maintain set temp, but it is unable to keep the tank heated under the circumstances. It does not heat any better than the Fluval 25watt heater that I had been using.

I use the 50watt in my betta tanks. (One gallon) and since its preset it shouldn't be to hot.

up to 90 degrees - - excellent .esp if your main heater is not made to adjust to your desired room heat temp - My daughter and her husband have several of these heaters too

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!

The label suggested to use it on 2 gal and up tank. Either you upgrade your tank or you could try this: test out on the 1 gal tank without the fish in it for 24 hrs to see if the temperature stay within range. A word of advice from someone who made a lots of mistake as a first time betta owner: do it right or you end up spending more money fixing you mistakes and hurts the fish in the process. If you decided to upgrade your tank, then it is better to get a 5 gal. It just so much easier to add on other needed features, such as a heater or filter (personally, I like whisper brand filter), etc..plus, your fish would love the evpxtra space to explore. Hope this is helpful. Best wishes for caring your fish.

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

I breed bettas and would never recommend this heater. I had these in 2 1/2G tanks and found it to be very unreliable. You are so much better off getting a heater that you can set the temperature on.

I am unsure about heating a Fluval 5 with this heater. I had no problem with the same scenario (set up heater at 78 degree in a 68 degree room), however I have a Fluval Spec 2.5 gallon tank.

I have a 40 gallon breader tank and it keeps it around 80 threw the mesh top with about room temp at 67-70...if I place it inside the rank it will keep it around 85ish...

Mine stays at 78 degrees in a five gallon tank with the temperature knob turned about half way, so I'm sure it will get to 82 degrees in a 1 gallon tank.

I have a 46 gallon cichlid tank and I bought a 300 watt heater. With the adjustable temperature control, I am able to keep it at a steady 78.4 degrees.

After the unit warms up (5-10 mins), it kicks out PLENTY of heat at the lowest wick setting. I've never tried keeping it at a higher setting because I haven't needed it. If you're warming <2000 sq ft, this unit can handle it at a low setting. Tank is 1.9 gal and gets me about 12 hours of heat, so north of 6 hours per gallon I suppose.

The only thing I advice for you to take a look is the length of the heater, this is my first aquarium and was told this is a great glass heater, so far I am very very satisfied. Well built heater. Consistent dialed temp.

Yes, but monitor the temperature very closely, I'm guessing your getting a Betta. If so the temperature should be around 80 degrees. I've been a fish keeper for years and my opinion would be get atleast a gallon tank. Half gallon is a bit too small for anything. My philosophy on fish tanks is get the biggest tank within your budget and space and save later before you realize you got too small of a tank for what you want.

I have the 2.5 gallon model under the bathroom sinks. It works very well. The owners manual doesn't show the max temp on the thermostat. The highest setting is not numbered. It says Max. I did find some specifications on line for the 6 gallon which stated the max temp was 140 deg. Jim
