since you're so badlucky with heaters, maybe it's time to buy a contrôler and let it handle the heating????

I never had a heater do that but I use a contrôler so it cannot do it.

This little guy saved my downstairs 36g twice. I could hear it beeping from upstairs.
Once was during a heat wave, so I bought a chiller.
Next time it went off was when the chiller stuck on and the heater couldn't keep up. Stupid chiller :mrgreen:

This isn't first heater you've lost this year, correct ?

this is why i bought a reefkeeper lite last week , ive had fish soup before and ill never have it again .A 120$ controller is worth way less than a full tank getting fried.
