Zoa colors fading from carbon dosing

[Galizio]

I use biofuel by brightwell, don't know if depends on what source of carbon you use, eventually mine are getting better but also lost some of them, the only thing I switched in the last few months was only the carbon dosing.
Actually since I took the kessil down and going all t5 they are doing better, but probably for some of them is a bit late.
