Reefing newb
ok so i have been battling cyno for well over 2 mnths. ive treated 3 times with chemiclean but it keeps coming back. my nitrites/nirates and ammonia are reading 0 (clearly there not) ive reduced my feeding to once every 3 days and only small amounts to diminsh extra crud. tryed blacking out my tank for 3 days, im scared to do it much longer then that bcuz of my corals. im using R/O water for water changes and im doing 25-30% water changes once a week. i would think that it is lack of flow in my tank but ive added 2 more power heads an the cyno is actually growing on my power heads! ive tryed sucking it out with my turkey baster, phosphate removers! What the heck else can i do?!
