This is my 2nd heater from this brand. It wasn't that I had any issues with the 1st one, I upgraded my tank from a 10g to a 40g and needed something stronger. This time I opted for the 500w. It is keeping temps perfectly at 75f. This tank is in the garage, so I'm curious to see if it's going to be enough or if I'm going have to get an extra one... It's October now in NY. Installation was a breeze and it blends in well with my tank. Specifically the tank I'm using it on is a 40g breeder tank with 1 Eastern Painted Turtle (juvenile), 9 mystery snails, 2 crayfish, and some minnows(?). It is not filled to the top, but is holding 20g of water.

Heater

Works great and i like how you can see the temperature from outside the tank because some time s the glass in side clouds up so you cant read it and it seems to work well .

Great aquarium heater

Works great. I love the digital display and additional LED light that lets you know when it's in heating mode. FYI, there is a small clicking noise when it turns off and on, but it doesn't bother me and you probably won't notice it unless you are sitting with no background noise. I have a digital thermometer on the side of the tank and it is always within a degree of where it is set. I would buy another.
