Water changes

[Acronuts]

Hello all,
When doing a water change in order to make a 25% change I need to drain to the point where sme of my sps's are actually out of the water.
I work fast enough that it takes about 10 to 12 mins for the new water to completely engulf the sps's and fil the tank once again.
I dont notice too much slim but do see some. The sps's usually recover again within
1. Is this causing stress to the animals?
2. Are there any other ways of changing water so that the animals are never out of the water?
As always your comments are greatly appreciated.
Juan

http://www.reefkeeping.com/issues/2005-11/eb/index.php this is an interesting article that sort of covers the topic about corals being out of water and what not.

I expose corals weekly with my water changes, for usually 10 min. or so. They show no effects and rarely slime. This includes SPS, LPS, and leathers. I wouldn't worry about it.

It's kinda like low tide situations, and waves swelling. A lot of the shallow reefs get "exposed" to low/no water intervals. my .02

Exactly what i was thinking. What do the corals do in the wild when low tide hits? They are fine. I remember i was moving an sps piece with puddy to a different spot in the tank and i pulled the Piece out and put puddy on the rock then my phone rang and about an hour later i remembered that i was diong that, put the coral back in and a couple hours later when lights on, it looked fine.
