Water Change Question

[angelmom]

My tank has been going great. I've had 2 loss of coral, one I think 1 was damaged at the Fish Store...it never made it, and the other was my clove polop (sp). Seems I had some lovly slugs on it that were feeding on it. I'm hoping to save what spread. I removed the old rock with the coral that was on it and all the slugs along with it. I'll keep my eyes out for any more and remove them accordingly. Just for a reference incase anyone else has the issue this is what I had arminid nudibranch.

My question is when I do a water change do I have to move my coral so it is not exposed? I've been moving it but it is starting to seem that it might be a silly thing to do. I don't want to be moving it ever time I do a water change unless it's necessary. Wouldn't it be more stressful on the coral to be moved around then to be exposed to air for a short time?

its ok for some corals to be exposed for a short period of time.

Depends on the coral. Generally things like sps, faviids, zo's, most stuff really is strong enough to stand exposure to air, particularly the shallow water things (and most corals in the industry are shallow water). They will just slough a bit of slime.
If you have stuff like euphyllia, bubble corals, that have soft, largely unsupported body structures, they can be damamged by exposure.

Sorry to go off topic but does the slime contain ammonia? NOOOB

 

[angelmom]

The coral that would be exposed would be Star Polop, a Zo and a Tourch. I would think those would be ok then yes?

for short time periods during a water change it would be okay but only for 10-15 min max and no I don't believe mucus has ammonia in it.......

I would be gentle with the torch. It will be ok if it's retracted so make it retract first. They have quite soft bodies

I agree.......they should pull in, just gently sweep your hand over it....before you drain any water.....
