hi,
well i have a 45 gallon reff tanks with approx 50 lbs of live rock and lots of corals, fish and inverts. just recentlly after i switched from a ton of flourecents to a MH 175...10,000K. it was all good for about 3 weeks and then all hell broke loose....for 2 weeks now i am having to scrub the tanks every day because this green stuff is growing so fast........i was told it was cyano....but im no algea expert so i have no clue..........its growing all over the rock and the glass and is really slimy lookin'. ill try to get some pics....now my question is that this stuff has to be living on something....i tested the water twice and the ammonia, nitrites, phosphates, and silicates came up zero. the nitrates came up at 12.5 which is what it is usually like, but the iron came up really high. is this stuff feeding on iron? oh and the ph was a little low but i added some buffer and its back up to 8.3. i have a penguin 330 on the tank and have a few power heads. i have no skimmer and have been doing fine without one for 6 months....could this be the cause? all of the fish, inverts., and corals are doing extreemely well exept for the montipora digitata (i think thats what it is) which isnt opening fully right now. so give me some answers if you got any.....im lost....help please!
