Help, my Zoo's are looking awful!

[UnderCoverDork]

Not too sure wha the issue is, i pretty sure its not my levels. This patch below has been falling apart for a few weeks now. I've looked and looked, the only thing i see that is not normal is these white strings and white "stuff" taking over the coral. im not sure how i should proceed any help would be great.

above are the zoos when they were looking good


below is today

have you moved the rock lately? How old are your bulbs? Is there to much flow on them? The "white strings" could be be spagetti worms, which are good scavengers but could be irritating the zoas. You could give zoas an Iodine dip with Lugol's. But I would try moving them or changing the bulbs first.

i moved the whole tank about 3 months ago, not much flow directly at them but the tnk has good flow, its a 20 gallon with a maxi jet 400 and 600 plus water movement from the water discharge on my prefilter box.

flow

flow

My bet is flow. Try a small powerhead in the tank, I noticed they are at the end of the tank, put the powerhead at the other end pointing across the tank.
Ive got flow out the wazoo, check out my video in another post(Zoos video) you can see if your flow is like mine??? The more light the better, and old bulbs really do change spectrum, and you cant tell with the humin eye.

Nice zoos I hope they live. Greg

Your first pic was a wild colony that you probably bought from your LFS. Those baby/sky blues like uber light and heavy feeding. If not they will fade and brown out, like what yours now look like.
As far as losing polyps, my guess is you have a predator. Have you FW dipped the remaining polyps? I would start there. good luck

No i havent dipped them yet..

and my bulbs are only 4 1/2 months old

what about the white stuff that looks like it is growing at the base of the polyps? should i take out the coral and remove all that stuff?

thanks for the help so far
