Hi Nikki!
Yikes, you do have algae problems! Put a powerhead blowing across the front of the rocks! Humor me on this, okay? I'll bet you a quarter, that in about three weeks you'll see a big improvement!
See, that's what I was saying in that other thread - even without added nutrients, the bacterial mulm in the LR is enough to fuel the algae. It looks like your spray bar is blowing it towards the front of the tank, is that right? Keep blasting out the holes in the rock with a handheld Phead every week, too.
Awesome tank!! You'll lick that algae!
