Help: SPS bleaching and STN

[ruslicus]

I had similar situation lately, but now it is getting better. My issue was UV module I have installed on my Illumina fixture and introduced BioPellets in system. after a month with BioPellets and once reduced UV level to 20% my Pocci reestablished colors and Acro is purple again. Additional I have started to automatic dose Alk and Calcium. Not sure what worked best for me but all together made a change. Good luck!
