Reefing newb
I have cyanobacteria growing all over my rocks, sand, and even some of my corals, I can not get rid of it. Can somebody please help me, I'm worried that it will suffocate my corals and stunt their growth. My light is brand new (bought it 3 months ago), I have a skimmer, 2 power heads on same side of tank, uv sterilizer, and a canister filter. I do water changes of 10% every week, testing every week, (all level perfect), and feedings twice a day. I was feeding every other day up until a month ago when I got 4 sea horses that require more feeding. I target feed my rtba and a couple of my corals. I also have 1 royal blue tang, 2 clown fish, and a goby (I think it's a green mandarin) 1 sand sifting star fish and another star fish that I can not remember the name of but it's a really skinny star fish that stays under the rocks and only comes out during feeding time (also target feed) about 30-35 lbs of live rock and a deep sand bed. I have cleaned and scraped the algae off the rocks, vacuumed the sand, and also vacuumed and sucked the algae up as I scrap it off. It's very easy to remove but it keeps growing back more and more every time I disturb it. I can't win with this stuff anybody have any good suggestions in how to get rid of it
