Good heater!! for aquarium heater and cooler

This heater is great, we have three of these for all three of our aquariums. It is supposed to be set to 78°, but never reaches it. It ranges from 75° to 76.6° on all three tanks. Other than that, there's virtually nothing to set up, just plug it in and mount it horizontally instead of vertically for best results.

Pros
  • Great for me
Cons
  • Some cons

Very good workmanship: aquarium heater and cooler

So far this heater is excellent. I have tropical fish and need my tank to stay at 72-74 and in summer my ax will cool my tank a lot. This heater seems very solid for the price and I love how it talks about both tank temp and set temp. As long as the heating is good. Will report if there are problems.

Pros
  • Best
Cons
  • Damaged

Buy this if you are afraid of house fires

So I was running around the house like crazy trying to figure out what happened at 8am and found the heater control box had melted was. to a crunch. Somehow there was even water in it, as if it had run into a cable from inside the heater and short-circuited the device. I bought this junk on January 22nd and now it's only July. Save your money and maybe your house and look elsewhere

Pros
  • Looks good
Cons
  • Not as good as it says it is

Holds my 120 gallon reef tank at 75 degrees

I am very happy with it. During the winter my 120 gallon tank was 75 degrees while my house oscillates between 60 and 72 degrees. It sits in my acrylic pan directly opposite my skimmer and hasn't had any overheating issues thanks to the plastic cage built around the heater. It has intuitive settings and it's nice to be able to look under the tank and see the digital temp and know it's working. I also like that it remembers its settings without power as I turn off the tank power completely when…

Pros
  • Heavy Duty
Cons
  • Interchangeable

ACCURATE AND EASY TO USE BUT REQUIRES A HANGER

This heater comes in a sturdy box protected with Styrofoam on the inside. The instructions for use are a bit questionable if you're unfamiliar with aquarium heaters, but they're easy to set up. The fact that the temperature control panel is on the outside of the tank is a nice plus as the water temperature can be easily adjusted without getting your hands wet. However, I believe this system could be made a bit more user-friendly if there was a way to hang the controller. There may have been…

Pros
  • GOLS certified
Cons
  • Available in black only
