cyano bacteria out break

[Troublekitty]

I'm currently battling cyano myself. I'm pretty sure it;s come from dosing NoPoX while possibly feeding reef roids. At one point I was able to read phosphates but now I get 0 nitrate and zero phos. I have the red sea algae test and they both show 0. I vacuumed the sand bed of all the cyano and stopped feeding but it still returns.

To my knowledge, carbon dosing would have no impact on cyno.....it would have an impact on nitrates and phosphates which combined with light...bring the green type algaes.

What is the TDS of your water source...are you using RODI?
The fast way is to use a red slime remover...but you should find the source or it may return.
