Green is growing on top of my rocks and on glass. Its not hairy, just starting to cover all of the rocks.
Tank is two months old. full of lr and ls. MH and pc lights.

the green growth is only on top of rocks (rocks exposed to direct light i think). Looks like someone spray painted the top.
Any ideas?

complete ro/di. installed seperate from house water. the rocks actually look great with the green but it'll get worse i'm sure.

Just let it go?

I had the same thing after my 10g was about 1 year old.
