Hello all, I am curious if anyone has any experience putting a reef in a greenhouse? I was thinking of doing so. I live in Northern California near the water and temps rarely get over the '70's. Our greenhouse is attached to the house and faces south. It gets lots of light, and the top opens to let the heat out. Sometimes it gets hot in there, but never for more than a couple hours in the middle of the day. By the time I get home from work, it is cool in there, even on days where is gets in the '80's. To lessen the risk and to use natural light I want to go open-top again. How about a tank without fish and just softies? Are corals more tolerant of higher temps? Is this idea a pipe dream? Ok. Maybe I should elaborate. The one thing that worries me is the heat spike in mid-afternoon. Will corals rebound well from a spike that approaches 90 or higher? Any rec's on coral? Leather, fox, bubble, or the like? ???
