Hello again , I was going to clean out my protein skimmer my monthly task and I noticed a bunch of slug looking guys or maybe idk they could be Copepod eggs hatchling?

I honestly haven’t the clue I’m still pretty new reefer.

also there is like a crap ton under my egg crate under the skimmer , like I’m talking a few hundred but they look dead ? I’m gonna to have to dump and siphon all water out from under there. I’d say a few hundred or so.

Anyways anybody know If this is normal or I could act immediately before gets worse....
