I'm not too sure exactly what type of algae this is but I can not seem to get rid of it. I have manually pulled it, treated it with Flix Rx and it still comes back. If anyone has any suggestions I'm open to them. I know my parameters are out of whack and im working very diligently trying to get them stable and under control. I do 10% water changes weekly using RODI set up but the TDI hits between 7 and 9 (we have horrible water) before filtering it reads 660. Im very new to the hobby and the tank is just shy of 1 year running it is a red sea max e260 and does not have the cabinet sump it is all in the back.If anyone has any advise I'm open to listen and thank you.

Alk 9.6 (apex trident)
Cal 648 (apex trident)
Mg 1358 (apex trident)
Ammonia .25 (tested 6/5 api test kit)
Nitrate 40 (tested 6/5 api test kit)

This is a combination of coraline algae and some diatom. You can siphon sandbed to clear.
As for rock, I would go with a combination of white light intensity reduction and clean up crew adding 4 turbo, astrea, trochus and nassarius snails.
If issue persists, I would consider liquid vibrant.

BY ANY CHANCE, IS THIS TANK AT OR NEAR WINDOW?

Thank you I will give that a shot. It is about 6' from a window that is on the west side of the house. There are shutters that cover the window and stay closed they are never opened. Unfortunately it was the only place I could place the tank
