Works on fish and aquatic animals

The heater in one of our tanks recently failed and had to be replaced. We put this in our 45 gallon tank and it works great. Ensures a constant water temperature. I also like that you can easily see the temperature. I would buy again.

Pros
  • memory function and wide compatibility.
Cons
  • Compatibility

Maintains the correct temperature in the aquarium

We had a problem with our original aquarium heater. We would adjust it a bit and end up with very hot water. With that you install it and it keeps the right temperature. It works so well. The instructions leave a lot to be desired, but I quickly realized that all I had to do was press a single button to install it.

Pros
  • Energy saving heater for the aquarium.
Cons
  • Poor repairability

Keeping my fish friends warm during our "winter "

I live in Central Florida and most of the time our house is too warm but not too cold. I bought an aquarium about 9 months ago and completely forgot that it will be about 3 weeks that the temperature in our house will be too low for our tropical fish. I used to use standard small tank dial heaters. Since I was using it on a large bow front tank, I needed a heater that I could select from a much more specific temperature rather than a general range. Direct instructions were absent, but setup was

Pros
  • Auto shut off when out of water.
Cons
  • Not sure
