have hope.
i just recently conquered my cyano problem with increased flow, phosphate and silicate remover,high grade activated carbon, weekly w.c.s, r/o top off with kalkwasser and a shorter lighting cycle. These are your best possible offense against that horrible bacteria. Also my lfs said discontinue w.c. s but i went with my gut and increased them and tried to siphon as much of it as i could each time. Sure enough i have wiped it out almost entirely after 3 months and no hope. Do what i have done and i assure you that you will beat it . PS the consensus seems to be that this is practically a right of passage to eventually have a successful reef.
