Are these Seeds?

[ObiTonyKenobi]

Had to tear down my tank to redo as BGA and BBA over took my tank. In the aquarium I had Crypts, Buce, and Anubias, along with some Bolbitis. For fish just had Corydoras and Runnynose Tetras. When I opened my Oase Biomaster and went into the main chamber to clean it I came across what looks like "seeds". I have no idea what this is but it was on all the sponges. If not seeds it looks like "tadpole exoskeletons" for the lack of a better term. Anyone ever seeing this?

they might be crypt tips?

I don't believe so, they must have been tiny to get past the prefilter and then spread to all the sponges. They are imbedded in all the sponges and free floating. Was thinking maybe replace each sponge slowly to not crash the cycle

Spring tail remnants? But you'd think if there is a lot of whatever it is you'd have seen the live version. What's the scale?

Do you feed any fresh foods? Maybe something organic that's broken up.

It looks like some sort of white bacteria, biofilm.
