I have two bettas each in a 2.5 tank with a light in the lid. They have two tanks each for easy changes. Do I need FOUR heaters? THX!

Switching the heaters from tank to tank should be easy enough. Making sure there are no sudden temperature changes is the hard part. With two heaters in two identical tanks in the same room this might work, but only if the two heaters have exactly the same setting. This might not be true. Just a degree or two difference is enough to stress a fish (says some web pages). You should check that the two tanks are at the same temp with a really good thermometer. I have just one 2.5 gal tank and change about 10% of the water daily by drawing off a quart (with a turkey baster) then warming a quart jar of new conditioned water by putting the jar in the tank for half an hour or so.

I would just get 2 of them and you could just switch them back and fourth. It's all up to you, your the buyer but I don't see a problem with just switching it if you leave the switch set at the same heating setting.

The heaters are easy enough to switch from one tank to another. I would just make sure the water in the new tank is the right temperature before you make the switch. The heater could take quite a while to warm it up if it's too cold. The big advantage of having 4 is you would always have a backup on hand.

I have these lighting up 2 dead corners in my 265 gal reef. based on where mine are placed I think you would need no more than 2. try one first holding over tank before installation to see how it works. you can always return the second if not needed. good luck.

I bought a Marina C10 Submersible Aquarium Heater, 10W. It works fantasticly. I put it inside the white tube, behide the filtersthere is plenty of room and it fits just right. The temp. stay constant and my betta LOVE this Aquarium.

No, probably not in the sense you mean. This is an eight watt "always on" type of heater, it has no thermostat. The heater will continue to emit eight watts worth of heat whenever it is plugged in. With very few exceptions all small "bowl" or "betta" heaters work this way, the only difference is the wattage. They are available in 5 to 15 watts, you need to match tank size, ambient temperature, and other variables to heater wattage. A thermometer and monitoring is essential, especially at first to determine what temperature a particular heater keeps a particular tank, and if room temperature rises so will the water temperature. The term "preset" is not really applicable to these heaters, preset heaters have a thermostat that is permanently set at a certain temperature. If a heater description uses the term preset without stating a specific temperature (usually 78) then it is NOT a thermostatic heater- it is an always on type. In too small of a tank or too warm a room these can overheat the water. Bettas are very heat tolerant, which is why using these heaters is feasible, but care is still needed. In anything under 3 gallons I think eight watts may be more than needed unless in a fairly cool room.

You would need the 5 watt size for a 1.5 gallon tank. This one would be way too warm.

There are heaters that work like a heating pad but they they don't work very well. So I would recamend getting a thermomitor as well. Betta can handle water temp as low as 74 and up to 84. An other option would be to get a real aquarum heater and a dish wash tub. During the evening or on really cold days put the whole no clean aquarum in the tub full of water and the heater. Good luck!

I'd personally get a smaller one. This article says 100watts is too much for a 10 gallon tank. Here's the reference article - http://www.thatpetplace.com/fish-tank-heaters-article

I only have a 29 gallon and my tank is loving the lights. My personal opinion is that it would be better to run two with a 60 gallon. Current is great though. You will love it!

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

A 40 Gallon should have a 200 watt heater... it's 5 watts per gallon is the normal requirement

My heater started working immediately. I suggest not leaving it out of water for any length of time. It will get hot to the touch very quickly. Even though it has a constant on feature, there is a limit to how hot the tank can get which is a combination of the tank size and the ambient temperature of the room. I am using mine in a 1.77 "goldfish starter kit" (who are they kidding) with an added external light and this heater and my Betta is doing fine. He is a classroom Betta, and my room gets cold!

Too small. 1 gallon is too small too keep any fish in, even a betta. Betta need at least 2.5 gallons of filtered, heated space. 1 gallon cannot be safely heated and toxins build up too fast. Please consider a different tank, preferably much bigger.

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 use it for a five gallon tank and it is great. A one gallon tank might be to small. Prior to getting this I had a flat heater that was under my gravel that auto censored to keep a tank at the right temp. The only problem with it was I needed to have more control of the temp in the. You might try finding it, sorry but I don't remember what kind it was, but I know it was for smaller tanks.

Hello. I wanted to start by noting the heater I received is not the one in the picture. It is shorter and thicker, and only has one suction cup at the top.That said, I bought this one because it was the lowest wattage I could find for my 1 gallon tank. The recommendations I found said 7 watts for 1.5 gallons and up, 5 watts for 1 gallon and up. I have not seen any for smaller tanks than that.

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.

I bought the Aqueon AQ10W. It seems to work quite well. It is about $15. I do not like that it is automatic and in summer it keeps the tank a little warm (about 85F). It doesn't seem too hot for the bettas, would prefer to be closer to 80F but they seem healthy and happy.
