I know the brown diatom algae looking stuff is normal in a new system but is it supposed to be thick enough to be able to peel off a layer of it off half my rock?? I use RODI water and I need the lights on for 2 corals I have I m just worried that I have an excessive amount of this stuff. I’ve got 5 snails in there but it would take em a year to eat this stuff
