Live Rock - Temp Question

[BantyRooster97]

So I have a brute with some extra live rock in it in my garage. It has a powerhead in it for circulation & I just noticed my heater has stopped working & the water is very cold, been in the 30's at night. Is this rock toast? Basically just wet rock now?
thx

Wow good question. Usually live rock doesn't need a heater but 30s geez I'm not too sure. In any case I'm believe some bacteria survived so I wouldn't call it just wet rock quite yet.

Bump!

I say there might be a cycle when the temps go up. But im sure enough bacteria survived to keep it live
