Working great love the adjustable temp control.
I got this for a back up heater for one of my many tanks.
Works great
This heater is awesome. Exact temperature that I need is there on point. I used 2 thermometers. And it’s 99% Accurate. I placed an airstone right under it to help heat distribution.
Perfect heater for my 20G Long got the 100W
This heater is a great choice for forgetful aquarium keepers. I am one of them. How many times have you been doing water changes on your fish tank when at the last minute you remember to unplug the heater. Well, this heater has you covered with the built-in alarm signaling low water level. It also has controls on the cord. It has it all and free, fast shipping from Hygger.
