After reading your post, along with the Elimi NP description section shown below, I decided to go with Bacto Balance for a week to see what happens. Apparently I should be using Bacto Balance instead of Elimi NP if my ratio is out of balance?
Anyway, I decided to give it a try. Couldn't hurt, since one month at the max Elimi NP dose did not work for me at all. After 1 week using the max Bacto dosage instead, NO3 went from 38 to 41.2, and PO4 went from 0.66 to 0.74.
So my starting ratio was 57, and my latest ratio is 56.
These results show that, after 1 week, my ratio got closer to the 10:1 ratio recommended for dosing Elimi NP by 57 - 56 = 1. Does this mean Bacto Balance is working to balance my nutrients, although very slowly? At this rate I'd have to dose Bacto Balance for another 46 weeks before I have a ratio where Elimi NP can be used. Does this sound correct?
