Live rock.
Freaky brittle star I found under one of the rocks (scared the shit out of me).
I’ve broken down the tank even more and have decided to a new aquascape. The above pic shows all the rock I’ve taken out of the tank. The massive rock wall I had going all these years created a lot of dead spots (no flow) and a lot of detritus settled in these dead spots, that’s been the cause of my high nitrate levels. More updates as they come.
