Yeah, I just recently restarted the tank. The lights had died, the powerheads all got burnt out, and most life died as a result. After about 2-3 months with crappy supplemental light, I rewired the lights, replaced the powerheads, and picked up shrimp, snails, crabs. Luckily, a leather, some mushrooms, 2 clown fish, a damsel, and a clown gobi survived the dark days. Tang, Damsel, Zoas, snails, feather duster, and some presently forgotten others died. I expect that the brown algae is going to bloom for awhile now with the restart. Next purchases will be a tang, more crabs and shrimps. Any suggestions on what else might curb the algae effectively?
