How old is the tank? What is your lighting and filtration like?

Do you have any flow along the sand?

About 6 months old

2x xr 30 45% par about 230 highest point 100 ish on sand

yeah ther is flow on the sandbed but a lot of lps on sand so not loads of flow

Good ole derbesia and diatom bloom. They happen in newer tanks. Shorten light cycle, increase flow and keep any filtration media cleaned and changed out.

Also, a little more information on things helps. Type of substrate? Clean up crew? Feeding?
