Need some advice... Tank not doing well.

Alrighty, if you're up for the fight then give'r hell! You will need to be patient and give the system time to recover. First things first, manually remove as much algae as possible and make sure that the system is stable (ie. no paramter fluctuations). Get a seahare and a clean up crew in there to start doing some damage to the general funkyness.

Next, you gotta starve out the algae and cyano. If you are feeling brave, I'd recommend VSV dosing with MB7 and skim the hell out of the tank. Take it easy if you go this route. 20% water change every week. Pull out all the guns!
