I noticed on my LR that there is something that looks like seaweed growing on it. It is a light -somewhat dark color and there is a green kind 2. It's coming out in sprouts(like a plant would). Is this seaweed?
Probably a macroalgae of some sort. Actually healthy for your tank. You can remove it if you don't like it's looks but I would leave it if it doesn't get to intrusive.
