Fuzzy White spots on coral

[Reflective]

I have an acro that has developed a couple white fuzzy spots. Looks like cotton attached to it. Is this a pest or just because my parameters have been out of whack?

I wonder if it a sponge of some sort.

It's stressed and releasing those white tuffs. I'd check your water quality... Specifically nitrates and phosphates and make sure there is no ammonia or nitrite in the water.

Those all say zero. I know my calcium, and mag is a little low and my alk a little high. So that may be stressing it out. I'll get some different kits for the nitrates and ammonia just to be sure.

I do have a boat load of pineapple sponges in my sump, but wasn't sure if they would grow on the sps

I've never seen or heard of a pineapple sponge growing on coral.

Anyway you can get a better picture?

Most likely mesentarial filaments...

I'll try in a couple hours when my t5s come on

So I noticed my Rock Flower Anemone is super unhappy as well today. I went and bought more test kits and the Nitrates are between 10 and 20 ppm. I'm going to do a water change and see if that helps stuff out.

I agree, the closest I have had is pineapple sponges growing in my zoas but not necessarily on my zoas.

Yup... For sure.
