If you are asking what I think you are asking I measure things this way.

Start with RO water.....should be about 10ppms
Add CalMag until water ppms read 300.
Add Pro Bloom until water ppms read 600.

So you will be watching numbers as you add things. Instead of adding a SET AMOUNT you will add enough to make the ppm numbers what you want them at.

Then add your zyme product and adjust the ph last.
