so I have a 90 gallon reef with a lot of SPS in it, its been set up for over 2 years now. Over the last several months Ive battled a red cyano problem thats gone from annoying to frustrating. other than some small random spots of bubble algae, I have no other nuisance algae to speak of in the tank. I have lot of coraline. The red cyano covers the sand bed, patches of rock and parts of the over flow box.
I have lots of flow in the tank. My nitrates always read 0. my phosphates always read zero, though Ive seen po4 jump when i add reef energy to the tank, but when I stop it just drops back down.
so im kind of at a loss for what to do next. Im considering dosing nitrate to balance out the nutrients to see if that kicks the cyano, but that could also makes this 10x worse couldnt it?
ive also considered carbon, vinegar, dosing with the hope of creating a competing bacteria in the tank to starve out the cyano. but since my nutrient levels are undetectable, I dont know how to start without a baseline nutrient level to base dosing off of. ive also read that carbon dosing can cause further nutrient inbalance which can lead to more cyano.
can anyone point me in the right direction?? and because i know someone will mention it, I do have red slime remover, Ive had it for a long while now but i really really really REALLY dont want to use it. I have a lot of expensive coral in the tank that ive grown into mother colonies and i dont want to lose them
thanks for reading
