Bad case of diatoms?

[South Carolina reef]

Hello. My tank is just over 3 months old. All parameters are in range. I run one mp40 on a mixed flow pattern. I think I'm looking at a bad case of diatoms. They were a brown color now more of a redish pink. They do seem to disappear at night. Is it safe to assume that cyano doesn't? Does more flow really help? I'm thinking I just need to power through it.

Do you have pics? Cyano also typically recedes a bit at night.

Very difficult to make out unless I turn my whites up and blue down

"reddish pink" is not diatoms.

Nope. Cyano also does a vertical migration up and down in sand.
