Hey guys,\n\nI know that new tanks go thru the stages of alage which is normal. Firstthe brown stuff, then the gree hair and then cyano. I seem to be stuck on cyano for a while now. But lately it has become out of control. Its everywhere on the sand, back glass and now its starting to cover my LR.\n\nIn all honesty, i have no clue where all this nutrition is coming from. I feed my tank the bare minimum every other day. I dont use tap water, my ammionia, nitrites and nitrates are all 0. When i clean the tank and remove as much of the cyano as i can, within hours, i see the sand turning red again.\n\nI have two questions: 1. Is this normal? if so, how long does this cyano stage last? 2. Can i do more frequent water changes. Say like 5 gallongs every other day until the cyano is gone? or would that stress the tank.\n\nThanks for your help. This algae is the worst kind i have ever experienced. I guess back then i should have appreciated the green & brown alage as they were alot easier to control than this cyano.
