I now what you mean Dejavue. I tried it with the zeovit additives but they proved to difficult to tweak. This is pretty straight forward and not I have the blessing of automated dosing thanks to the profilux set up. That I think has been one key to this working out for me. I set it and can make minor adjustments and then watch for a while without any manual input of additives.
I am also a believer in the 3 part additives and/or balling salts. I am adding Potassion (BW) and Ferrion(BW) along with lugols once a week now.
