ID Help please - White things in sump

[Raxnar]

Still learning lots as I go!
a whole bunch of white things have started showing in the sump.

At first I was thinking baby snails but I have no snails in the sump. They could end up there when their eggs free float in the water. but not 100% sure.

any reason to clean some of them off if it completely covers the sump glass?

Only for aesthetics if you want to. They are filter feeders and will control their own population for the most part.

@Raxnar , If they are like you say in the sump, leave them alone (if isn't for aesthetic reason), they do good job as a filter feeders, they will control them population by the pollutions in the water, which can be sign of good bio load and too much of some elements. (read about pineapple sponges what they are feeding on, and that will bring you the answer what kind of stuff you have too much, probably you have to get control of that xD), otherwise they are part of the good CUC
