Have patience - you posted late in the evening and it's just now morning.

It looks like a new tank and the brown stuff looks like diatoms but without more clear photos or information about your tank, it's tough to tell what's going on.

How long has the tank been set up? What are your parameters? Are you using CO2? What's your lighting? Ferts?

Tank is a new one so diatoms would make sense but I thought those just exist on the glass. I'd say 1 and a half months for the tank. Lighting is high. I've got 2 13w cfl 11 inches above the substrate. I've got co2 at 1/2 bps. Installing drop checker today. pH: 6.9, Tds: 270, gh: 8, kh: 4
