Hello everyone was wondering about getting help IDN this bacteria in my fish tank to me. It looks like cyano. I don’t see any diatoms under the microscope. My phosphates were really elevated but all other parameters are in check so I dosed phosphate E extra carefully to not harm any fish or coral and have brought it down to a 0.02 over a extend period of a week to make sure nothing would be shocked. Any advice is great, ps my tank is going on 4 years had a crash one year ago due to a failed heater while out of town for work. Not new to reef to reef just new account as other was lost
