Convinced of a link between GFO and Cyano (and not the good kind)

Before you start your LC dosing (which I have not done, so only passing on what I read), I know that Reefsupplycanada used to sell 10 micron socks to use with Fozdown. I would hate to see your tank suffer another mysterious set back that may be ultimately traced to LC flocs that escape your 50 micron net.
