Is this suitable for a gallon tank? If not what size heater should I buy? Thanks!

Hydor also makes a 25W heater, which works the same, but is smaller and might fit in your tank better.

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.

This heater will be overkill for a 1 gallon tank. There are very few heaters that are designed to work well in a 1 gallon tank. Can you choose a larger tank? Larger tanks will more water volume will be more stable in every parameter - leading to improved livestock and plant health, as well as easier maintenance.

This will be overkill for a gallon you should get one of those pads that you put under the bowl.

This easily/consistently keeps my 10G tank at 78-80F. Should easily suffice for a 1G tank. You could go w/ less wattage but I don't recall saving much $ over a smaller one.

This "tank" is only 2 gallons and the surrounding air in your home should be warm enough for any fish that would be suited for this little tank. Also, it's plastic, a heater would probably damage it...

It'll heat a 5 gallon tank just fine. Be sure to purchase a thermostat, if you don't have one already.

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...

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

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!

According to Eheim, the following heaters should be appropriate:Model 3616 150W heater: 53-79 gallons (US)Model 3617 200W heater: 79-106 gallons (US)If your tank is in a room that gets very cold in the winter, you might want to go with the 200W heater.

I'm using it in a 3 gallon Tetra Cube. As long as it's submerged horizontal or vertically, and not touching substrate, it'll work. The heater is 6.5" tall x 2" wide. I like it because, it heats to a set temperature; if the tank is too warm, it shuts off. I've been using it for a month, checking with a thermometer, and it's been spot on 80, as set for my Betta.

This won't melt your plastic tank and probably won't heat up the water. If you but a better heater, you should also change your tank because it could melt. Since you just want a small tank, you should just buy a big glass vase to save money

Yes. We have our heater installed on a 30 gallon tank and works just fine. A GREAT HEATER

This heater kept my 2.5 gallon tank in the low-mid 80's. Way too warm. I ended up replacing it with the Hydor 25W heater because it has a dial to set the temperature. It's much more reliable. Though this one is 3.75" and the Hydor is 6.5" long.

I wouldn't suggest it as it is only 7.5 watts and will not raise temps. You should use a 75-150 watt heater if you have tropical fish. This heater at best would likely only take the chill off of just a 5 gallon tank. Not enough to really help.

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.

Not a problem... I'm using mine in a 6 gallon acrylic tank and I'm very happy with it. Keeps the tank at 75 in a 60 degree room through the winter. I would recommend this heater you wont be sorry.

It probably won't even fit, but even if it does it would overheat one gallon before the thermostat could shut it off. A 25 watt heater is really meant for a 5 gallon tank or better (3-5 watts per gallon is the general rule). Small volumes of water usually don't provide enough water circulation for heater thermostats to function properly.

Its very possible to use this for a 250 gallon I have a 125 and use this 300 watt well below what's recommended for my tank size it keeps it very warm and its very durable I have large Oscars in my tank u can only imagine try contacting a pet smart and see what they think u may have to purchase 2 but its still great at the price amazon has it versus pet supply stores there normally $50-60 bucks at pet for just 1

Yes! I kept this heater in my 1 gallon corner tank in which I kept my betta fish. Depending on the species you plan to keep and their temperature preference you need to be careful because one gallon of water doesn't take much to heat. If you are using a light with the tank, this could add heat, too. If left on too long this heater can get the water in to the mid to high 80's, which is HOT... Too hot for most fish. I would absolutely recommend buying a cheap stick on thermometer... Usually within about 4 dollars. To summarize, this heater is acceptable for a 1 gallon tank. Probably one of the most fitting, actually. Just keep an eye on the temp. until you figure out your routine.
