Exposing corals to AIR/LIGHTS bad during water changes??
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. |
It is fine, don't worry. Corals deal with this during low tide all the time. Hell, I ship corals dry.

I always expose my corals to air when transfering them to my tank, and during large changes they are exposed, but I try and minimize it if and when I can. |

But I still believe that often times people underestimate how hardy these corals are. I've had SPS colonies, not frags, out of water over night and they were fine. I am not saying I advocate getting the corals out of water for hours and hours at a time, but they are well equipped to handle it. |
assuming they are healthy to begin with :thumbsup:

:fun2:

As long as they are exposed for say 15 min or less thats fine but anything more i would worry about them drying out.
