Zone will kill off of your beneficials and enzymes. Add Zone to the res before you add your nutes. 1ml per gallon is a good place to start up to 2.5ml per gallon if you are having problems.Jack/UCMENOW
If I'm using Hygrozyme and I want to switch to zone do I need to do a completle res change or can I just start topping off my res using zone? I haven't changed my res in 3-4 weeks so I don't know if there's any zyme left in there. My system is rock stable and don't want to mess with it unless I have to. So at what level do you use zone 1-2ml/gal? and do you add to daily top off or do you add weekly?
I dont doubt itI wonder how it would be to go a full cycle without changing the water.
I bet its completely possible.
