I didn't want a non-adjustable heater for my 3gal tank, but had trouble finding one that didn't have crappy reviews. This one keeps my tank at 81°, just like other reviewers have stated. Too warm for my fish. I'm disappointed and will be returning this once I get a replacement.
I ordered this for my 1.5 gallon betta tank and it keeps the temperature within the required range. It is small so it does not take up much room in the tank. My betta has taken refuge at the top of it, which is odd because he has plants, leafs, and a tunnel to hide in.
I bought this to keep my betta warm as we keep our house a little cooler in the winter due to heating costs. This was a perfect choice. Easy to use and quick to install. I took off 1 star because I thought it came with a thermometer on it but it doesnt, and because its on the bigger end and a bit too large for a 2gal tank.
The heater lights up but after a few hours in the tank, the water is the same temperature as when I put in and when I touch the heater, it isn't even warm. I have a gallon and a half size tank.
Had a hard time deciding on a heater because of all the scary reviews I've come across. I've had this one for five months now and it's still working great! I bought 2 so I have one for each of my fish tanks and I haven't had an issue with either of them.
I received the water heater but it is missing the thermostat! Pls send the thermostat
This heater is keeping my now fishless cycling tank at a toasty 82 degrees F, a little on the warm side. I am probably going to find another small heater in store and keep this one as a back up, as it hasn't dropped below 81 degrees F
Although red light is on it does not warm up the tank
This heater seemed to work fine for a while. Then our betta fish started acting weird. He would hide in his house and only come out to eat. My husband put his finger in the water when feeding the fish and got a shock where he had a cut. He thought it was something in the water but when he poured the water over his cut he felt nothing. He unplugged the water heater and put his finger in the water again and no longer received the shock. The fish immediately started acting normal again, swimming around freely and no longer hiding.
I got this nice lil heater for a 5gal tank. I do wish there was a switch to turn the temp down, since thermometer says fish tank is 80. Luckily I don't have a fish yet since I was letting the tank cycle.
