Cannot choose the size
Answer by mossbackApr 29, 2022
3-5 watts per gallon.

Does this shut off to maintain the desired set temperature?
Answer by ChewySep 17, 2018
The unit heats only when the pilot light is illuminated. When the pre-selected temperature is reached, the pilot light shuts off. It will light again only when the heater is required to maintain the temperature at the selected level.

Is this the heater I need for a 5 gallon tank. If not what do your recommend please
Answer by ChewyAug 12, 2020
The Fluval Submersible Glass Aquarium Heater is suitable for your tank, it is designed to work in tanks up to 15-gallon (fresh or saltwater tanks).

So disappointing

I bought this heater for my 29 gallon setup. It had been recommended to me by several people, so I splurged on it. So disappointing! I'd keep turning the temp up and my tank never went above 72. I even adjusted the dial as high as it would go and the temp stayed at 75. Don't waste your money on this heater!

Excellent purchase

The best aquarium heater I have purchased. Extremely accurate and the appearance in the aquarium is elegant. In fact, I am purchasing another one to replace a different heater that I purchased that is NOT heating the aquarium sufficiently.

Too big for 5gallon

This is too tall for my tank. I have the 5 gallon Aqua Culture starter kit and it’s much too tall for my tanks water level. I’m sure it would work fine for a taller tank. Definitely going to try to return.

Great Heater

Pretty nice heater. I was sceptical about the glass cover but it does look nicer I think than plain black. The picture does not do it justice. I have it in a 5 gallon nano so no, it does not fit in the filter area if you keep the sponge. But it is fully submersible so you can put it like mine in the tank. The downsize is it is visible, the upside is it has no issue at all keeping temp. The smaller size ones might

very noticable

This heater works OK. I have the white Edge tank so the silver and black on this heater make it very noticable, and due to it's large size, it's hard to hide. The best way to hide something is to make it blend in. This does not.

Excellant!!!!

I have a 6 gallon tank at my office that I got a preset heater for. My beta on the weekends when I wasn’t there the tank would get slight chilly for a betas liking. This one is preset to 80 and he is warm even on the weekends!

Fluval heater

Very satisfied. Heaters can be hit or miss but this one is working, Only 3 weeks, like it should. I am hoping this one lasts for years like the other Fluval heaters I own.

Fluval Heater

I bought this for my beta tank, I set it up and everything and it doesn’t work. I don’t even think it heated up at all
