The reef gods have it in for me!

My 2 cents worth !
I don't have a DSB merely 1.5inches of Sugar aragonite, my tank in in quarantine (no fish) since I have had a bad ICH attack and decided to run empty for 5 weeks ( diificult on patience I tell ya) so I do not feed ... I still do water changes and guess what... cyano on the bottom ... Mind you not as much as before but still you would think that without nutrient it would have starved but no still there and I suck it out as soon as it appears so ????
