White spores all over sump and plumbing

[Alphadave248]

I’ve noticed over the past few weeks these spores attaching to the dark and low flow areas of my tank. Specifically in the sump on the bottom portion of my skimmer and in the plumbing box up too in the DT. Should I be worried? Seem to be harmless thus far, but I’d like to get in front of it if possible.
Additional note: I can scrape them when attached to the glass or back panels but the plumbing is a little harder to get to.

Edit: alkalinity is now at 8.1 after tonights dosing

Look like sponges or something to me. Filter feeders. Nothing to worry about.

Hard to see in pic but appear to be pineapple sponges, harmless.

+1 for Pineapple sponges, don't worry, they can't harm anything at all, filter feeders, which are the easiest to be cleaned if need, and can't make any harm to your system.

pineapple sponges, they love living in my sump and on the underside of my rocks. filter feeders...wish my fish ate them as they are an eye sore.

Agree! Just looks messy when everything else is so perfectly taken care of ya know.
