I have 2 Visi-Therm heaters what crap, I have had I blow up, the one I use to make water for water changes is now full of water (less than 1 month old) and the one that replaced the one that blew up is not staying on (just over 1 month old)

What do you all use and how long has it been going for you on what size tank?


Thanks
