Started dosing bacto balance to help balance out my N/P ratio. When i started to dose nitrates were around 30 with phosphates between 0.02 - 0.05. While dosing bacto balance my phosphates are bottoming out and most readings show up as 0.00 on the Hanna ULR, while my nitrates continue to creep up. Should I switch to elimi NP? Any help would be appreciated.
