Im experimenting with DO/DI & tap water mixtures to get the correct ratio when I thought of something: should I even be using the DI when I will be adding tap water & Kent RO Right back in anyways? Or does the DI filter out some things that will not be put back in, in which case I should continue using the DI? :fish1:

My tap is about 390ppm, so Im thinking of using 3 parts RO/DI & 1 part tap. (0+0+0+390)/4 = 97.5ppm.
I may add a little bit of Kent RO Right too.
