i collect cyano cures in a certain thread. we're out 35 pages now simply cleaning the tank, but differently than you did. more thorough, all at once
if you have the gallonage that allows you to willing deep clean our way, Ill give you a 35 page no loss likelihood we can simply clean your tank into compliance. post a full tank shot
dosers and meds like chemi clean, add to systemic waste loading in physical and chemical form, so we're against that
in our thread, we fix cyano problems in two hours by being opposite of what the masses do. if your tank is large enough its not worth the work to deep clean it, and possibly even change most of the water, then several dosers are avail that might zap it, this round.
