Hi everyone. Recently, I have been facing a small dino issue. Since the two pieces of coral died (for reasons I still can't figure out), I decided to do a blackout. Right now, the water is extremely murky. I will take pictures but it is nasty and the smell coming off the tank is also terrible. Anyone have any suggestions as to what to do? I change the filter floss daily and run carbon but it doesn't seem to help at all.
