What are some techniques used when performing water changes when you have corals that are located in the upper portion of your aquarium that can't be moved?

Do it fast....LOL....I have a frogspawn that is pretty close to being uncovered when I take the water out....BUT I also start putting the water back in as soon as it is out....so it is uncovered for a VERY short amount of time

No problem....just trying to get some ideas since I have a few corals that I can't move when doing water changes....I normally try to do it as quick as possible.

some of my corals are exposed for 10-15 minutes when I perform waterchanges. I just make sure I splash water on them every few minutes. so far no casualties (in Years of doing it this way). I also make sure my lights are off when I do the water change so there is no photoshock.

Low tide happens and corals can be exposed to the air for an extended period of time, that's one reason why they create a slime barrier.
I do what reefkprZ does; use a turkey baster or something to keep the corals at least moist if they'll be out of the water for a while.

It has been times my top layer of coral has been out of the water for up to 20 minutes, but as stated above make sure they don't have a chance to dry out. If you are doing your water changes from a bucket to the tank use a pump or a power head with a tube to make it a little faster.

Yes low tide that is exactly what I was thinking. I have a few corals that put off a really heavy slime coating. Shouldn't that be dipped out after the water change? Isn't the slime coating use also as a defense mechanism. So I'm thinking if its not dipped out then it could drift onto another coral before it is filtered out? Thoughts?
