I got some PHOS FX resin from Marinedepot a safely rechargeable resin that has high capacity phosphate removing power. The label says it removes 10ppm in 250 gallon aquariums. I have .55692 ppm phosphates in a 300-320 gallon aquarium. However, the label doesn't say how much of the resin to use to remove small amounts of phosphates. I don't want to remove all my phosphates over night, I'm just trying to manage them. I'm doing daily water changes (5% or so) each day to lower them. I have a Hana ULR tester I just got to test them. Once I get them down to .05 - .1 ppm then I'd like to add the resin as a way to manage phosphates ongoing. I got 500 ml of the resin. So am I supposed to assume that the capacity of 500 ml of resin in 250 gallons of water is a total of 10 ppm. How much will it remove daily? Will it just bring it down to 0 in a day? Or .01 per day until 10ppm is reached?
Anyone have experience with this resin for phosphate removal?
