I know this has been asked probably a billion times so I'll make it a billion and one...
Is the pic below cyano? I'm guessing it is, I only have RO water and I don't have a phosphate test kit. It started showing up before I added any fish in the tank so am I correct in assuming my phosphates are high?
BTW, the thing on the right is a fake coral my kids gave me and is naturally that color - my concern is whats on the sand.
TIA
