bubble coral help

4ptbuck · #1 04-07-2005, 04:49 PM

I have a green bubble coral in my tank that now has some brown colour to it. When I first bought it, it was a 'pure' colour. Now it looks like it has mildew inside it.

It is currently located at the top of my tank, directly under 2X96W ( 10K and 50/50).

Does anybody have any ideas what might be happening? It has slowly developed, and the 'mildew' seems to be spreading.

I got a feeling it might be getting too much light, as the portion that is not directly under the tubes seem to be 'cleaner'.

Here's an earlier pic.... It's worse now.

I've got the same one. I find that if I don't feed it, then it gets a little brown. Are you feeding it anything? I try and feed it mysis 2-3 a week. Watch out, they eat and ton and grow very fast.

I have been feeding it occasionally.
I get some blood worm floaters, or mysis floaters on occasion.
Other times, I give it a piece of scallop or shrimp. Maybe twice a month?

Should I feed it more?
Is it possible to overfeed? ie will it reject food if it is full?

i know they don't like to much flow either. im about to get one as well and have been doing some reading.

That might be an issue. I have a PH blowing across the top of the back. There is flow, but not enough to wave it around too much.

just another thought.
Originally this coral was under a 96W 10k and a 96W actinics. I have change the lights out a few months ago and now it sits undet a 96W 10k and a 96W 50/50. Could it be that it needs more blue? Should I put the actinic back in?
