I thought of that but now I'm wondering that if I do that, i'll start at 80 and then when the lights come on, won't it raise the temp up again? I feel like I'm overthinking it. LOL!! Also, I had a number of SPS
corals in the tank which perished in the heat of the summer last year. I really don't want to pay a fortune for a chiller. Has anyone been able to keep the water temp down by other means? I'd love to replace my sps
corals but it would be dumb unless I can keep my water temp steady. I have heard that putting a fan on the sump helps keep the water temp steady as well. Any thoughts on that?
