Hi everybody ~
I know this question has been addressed before but I can't remember the answer to it.
In my sump & on the pumps, too (no where else, it seems) I have noticed these very small, calcareous (correct term?? Anyway, you know what I mean) worm-type critters. Are they beneficial* anything to worry about? It makes the sump & equipment look a bit unsightly but, I didn't want to do anything til I got some input. Any ideas?? Tks - Chess
