Cyno help (1 Viewer)

[frankgrem]

I got rid of my cyno and it is back again. Any suggestions or advice on sites that I can go to. I use rodi and all water parameters are good. I make my own food, only feed twice a week and don't over feed. I tried leaving the lights off for a few days and that helped for about a month but it is back again.I won't use chemicals so please don't suggest anything but natural treatments.

Thanks

Frank
