Hair Algae
I know it's been a while. Here's an update, I think I got the hair algae (see pic below). I've adjusted feeding, lighting, and flow. I've added 3 Nasarius Snails and will be getting an emerald crab. I'm writing this now cause I've been freaking out for the past couple of days. This combination seems to be working but there are still plenty of trouble spots, that's why I'm getting the emerald crab.
