question about pps pro dosing

Personally, I wouldn't use it but I'm no expert on the chemistry involved. It would just make me nervous. Especially since PPS method is all about a balance of nutrients. Some of the ferts formed into a clump and will not make it into the liquid you will put in your tank. There wouldn't be an easy way to guarantee that the different ferts are balanced like they were when you first mixed. Just my 2 cents.
