I am having a bit of a cyano problem, well.... its never ending. I have a 65 gal. that has been up for 4 months now and have been fighting a major cyano problem for a month! I take a turkey baster to it I suction it off the sand during my weekly water change and the darn stuff keeps coming back
. My tank looks beautiful for a day after a water change then the stuff starts taking over. I have a 25 gal. sump/fuge with about 10lbs of life rock in it and in the main tank has 70lbs of live rock, a bubble tip, frog spawn, false clown, yellow tang, and a pink spotted golby. Help me please.
