My po4 has been zero since I set up my tank, can't get it up. No3 is between 0-1. Corals are either dying or looking bad. Zero growth. Also have traces of brown algae which may be dinos, not sure. I'd love to bring up nutrients but when I up the feeding tank looks filthy and brown algae seems to cover the glass daily, like a dust mat. This tank is killing me! Lol. Advice appreciated. Maybe more fish? I have a pretty good stock in my 150 though. Hippo, yellow, scopas tangs, blue throat trigger, 2 clowns, 2 Bartlett, big orange sided wrasse, lamark angel, tailspot blenny. Pretty much all sps fade and get burnt tips. Birdsnests dont stand a chance. When the algae first appeared i attacked it with bacteria. I think that I have to much bacteria and stripped my water of nutrients.
