Well..if youre comparing it to standard EI, which is 1.3 ppm 3x per week, for a total of 3.9 - along with 50% water changes, you will eventually be rolling with close to 8 in the water due to accumulation. I change nearly all the water and go back with 9. So its not as much as it sounds like when you factor in wc volumeAny guesses as to why your tank needs so much P since normal EI levels are only about 3ppm?
