An issue came up that I never thought about before after talking with the latest TOTM winner. He does weekly 10% water changes and I was wondering if that was an issue with exposing corals to air AND/OR lights. He said his change takes 10-15 mins. , he has only actinics or something on, and the corals slime a bit and that's all.

I never thought about this before. Never read anything about it either. I never thought it an issue. I know... sponges... maybe few things like that are no good exposed to air. But in low tides some corals are cooking in the sun and survive. Is this an issue in a REEF tank??

I personally take 2 hours cleaning etc. till I replace water... I need the lights on so I can see... and with 30% change my water is pretty low.
