I'm just curious how much everyone doses Phosphate? How much per dose? How many times a week if multiple and maybe an overall weekly amount they add? Not sure how accurate my Phosphate test kit is but usually reads around 1-2 ppm. I just read a post from Tom Barr where he said he doses 5 ppm 3 x week, curious if others dose this much? I want to increase mine and see what happens. I've been adding about .15 grams which the calculator says 1.38 ppm 3 x week. I'm thinking I should be dosing more.
