growing frags in sump?

[tang daddy]

well looks like a good start, make sure you have decent flow like a few extra powerheads.....

I ran a sump grow tank. I used a 250W Hamilton pendent over it. The light alone added about two degrees to the water. The extra powerheads added another 1-2 degrees. Other then that I had a real issue with hair algae and bryopsis in my sump. It did not grow in the main display though. I always run a chiller so the temp never rose above 81 degrees. But without the chiller on the tank would rise above 86 degrees. Atleast that was as far as I let it go. You might have to run a fan in your stand.

Figure as basement sump and with fans would be able to keep the heat down but the nuisance algae and even stuff like coralline is a concern.

I had mine under the stand . You should have a easier time at getting rid of the extra heat then.
