Mini Heater - 10 Watt

Because that's what my tank was at when I came home today. The ambient room temperature is 68.9F, and the aquarium thermometer is reading a clear 92F. It's a good thing I haven't put any fish in there yet.

I have been using this heater for months know in my Fuval Spec III (2.6 gal.) and have no complaints. I have red cherry shrimp and two blue danio babies ;) This heater is slim in design and fits into the back pump compartment of the tank (with a lot of room to spare). It does run on the warm side. In the back pump compartment of the tank it stays at a constant 79 Fahrenheit. However in the living space of the tank it stays about 77-76 which is fine. NOTE: I have only used this heater during winter months. When it warms up outside I will likely not use it as cherry shrimp don't like it to be too warm.

If anyone doesn't know what I mean by the "pump compartment of the tank" just look up some of the Fluval aquarium filtration systems and how they are built in to the tank.

Hope this helps ! For me this heater is PERFECT !!!

I bought this heater for a 2 gallon tank that houses one Betta fish. I live in Southern California, so the ambient room temp is around 70 degrees, but wanted to get the water 6-8 degrees warmer for his comfort. I bought this heater and thought with its claim to hold a constant 78 degree temp I'd be set. I left for a weekend and when we came back the water was 90 degrees! (Thankfully our Betta appears to be alright) I definitely do NOT recommend this heater. It's far too hot for a small tank.

I live in Northern California and just got a betta a few days ago as a christmas present. He's in a one gallon tank for now. I noticed the next morning he was not moving and thought he may be cold. After googling and realizing they are supposed to be kept between 70 and 80 degrees, I freaked out and bought this heater from a shop around the corner (it was the only one they had) along with a thermometer. THEN I decided to read the reviews on amazon. I panicked after seeing all these terrible reviews and didn't know what to do. I didn't want to boil my fish but, now that i had a thermometer, i knew my fish's tank was 58 degrees! I figured he would prob die from freezing before i could get another heater so i just held my breath and plugged this one in and went to bed.

Next morning he was 74 degrees!! YAY! All was right with the world. I worried about him while at work but came home and he was still at 74 degrees! I think this product works just fine if you actually live in a cold climate. If you live in San Diego, well then you probably don't need a heater in the first place.

We got this heater because our betta fish, Marco, needed to be warmer. We plugged it in and went to the zoo. When we came back, Marco was laying on the ground dead and the water was at 92 degrees! Marco was my favorite fish!
