The fauna system operates off the same idea, running ultra phos. With the carbon dosing.
From what I remember the red field ratio is 7:1

Yeah, if you don't want pale Acros you have to feed them. Or you can use the ZeoLites, but use less of them. There are all sorts of combos, but you really should subscribe to a whole system or it doesn't usually work the way it was designed. ZeoVit is all about balance. It's great for people who like to tweak things - terrible for people who don't.

Redfield Ratio (C)106 : (N)16 : (P) 1
