Echo plus 1/4 hp chiller

[Slyguy00]

Thats a bit scary considering i also rely on my chiller to control my temp. But I do have a heater just incase. Maybe its time to invest in a reef keeper..

I second the suggestion of a temperature monitoring system. Runaway heaters (or chillers in your case) are not uncommon.
It doesn't have to cost an arm and a leg. A basic unit that will alert you of temperature outside of a user-defined window can
be obtained for roughly $120. Anyway, glad to read that you got away with little damage.
