Cobalt Aquarium Fish Tank Heater Review Easy-Therm, Neo-Therm, Accu-Therm

Submersible Aquarium Heater Review | Cobalt Heaters Review | Cobalt Easy-Therm, Neo-Therm, Accu-Therm Submersible Aquarium Heater Review | Cobalt Submersible Fish Tank Heater

Today I go over the features of Cobalt’s line of aquarium heaters. I show you the differences between the Neo Therm, Accu Therm and Easy Therm submersible fish tank heaters in this test and review. They are all very easy to use and offer a 3 year warranty. We put these submersible fish tank heaters to the ultimate test in an extreme cool down test where our house temperature drops to 18 degrees Celsius and these heaters are tasked with keeping the tank temperature at 27 degrees Celsius, an almost 10 degree temperature difference when the manufacturer rates them for up to a 6 degree difference. Will the Cobalt submersible aquarium heaters keep up? Stay tuned to the end to find out.

thats really good to hear. I just purchased 3 heaters yesterday. Im getting nervous about winter. All my heaters have some sort of condensation in them. Peole say thats bad. But i never take water below heater during w/cs etc. I think its just the normal. But to be on the safe side i got back ups.

Maximus Aquatics says:
