Wondering about brown on LR? Help?

[Pholder]

My question is this:

My LR has started to turn brown. It's not slimy or hairy. My tank has been running for about 1 month. Is it part of the cycling process? is there something that I should do to stop it? I am leaving my light on for about 9 hrs at a time right now, could that be fueling the brown stuff?
My parameters are

PH 8.3
Nitrites: .5
Nitrates: 0
Ammonia: .50
Temp: 78 - 80 F.

Diatoms. Totally normal part of cycling. It will subside and you probably will get a hair algae bloom as well. Again, totally normal. They both will go away on their own. Continue to use RO/DI if you aren't already. Silicate feeds diatoms, the lights won't make a difference. ;)
