It could be diatoms and bubble algae on top of it.

How old is the tank?

What are your nitrate and phosphate levels?

Emerald crabs eat bubble algae or you will need to carefully remove it without puncturing it.

tank finished its cycle mid March, but water has been running since beginning of Feb I believe.

according to hanna kit, phosphate is 0. I am picking up another ki today to compare to the hanna kit.
