This product is made for use with 30-40-gallon aquariums.

I know it's preset for 78° but are you able to adjust it manually

Heater sucks

This does not heat my 40 gallon tank at all. Doesn’t even turn on anymore and I only had it for less than a month.

Never worked

I bought this heater about 2 months ago for my 10 gallon aquarium and unfortunately it never worked. I am extremely disappointed that I wasted $30 on it.
