Does anyone know what this js? And how to treat? Growing all over the sand and rocks.

From the one pic, it looks like it may be cyanobacteria. Does it blow away easily when disturbed? If it is cyano, manual removal, water changes, good flow, and making sure your water parameters are in range can help.

Confirm it looks like cyanobacteria. Is it less obvious just before lights turn on in the morning? Cyano can photosynthesize, so it tends to get worse as the day progresses.
