Hi

Your phosphate seems ultra high - should be 0.1-0.2 (max) are you using tap to mix salt? If not have you checked your RO water. I would start by looking at that. Do a phosphate test on your salt mix first and if that is zero then move on from there. If your salt water is ok then maybe you have something leaching it back into the water (porous rock/sand perhaps).

In the meantime I would be vacuuming the sand bed and manual removal from rock if you can to try and beat back the growth. It's tough but you will have to stick at it. We had red cyano that was very persistent even though our parameters were 'ok' - we were doing weekly sand vacuuming - then washing the sand that made it out of the tank in tap then rinsing in RO and returning to the tank. Took a few months but eventually a balance was restored.

Good luck!

I’m using RO water from my Mix Station
I will test it.
Thank you
