I have a 75g with a 30g sump and skimmer that is under 12 months old. Last week I noticed some pineapple sponges in my sump, and today I found some other weird things. I’ve been told the one I’m my skimmer tube might be a spaghetti sponge, but I’m having trouble finding information on them. The other things on the walls of the sump I have no idea, and then my husband found this other thing floating on the surface of the water in the DT (did not appear to be independently mobile). Please help me figure this out.
