How much Granular Ferric Oxide in grams does it take to reduce phosphate levels by 1.0 PPM in 100 gallons of water? let's say I leave it in for 1 month? My levels are between 2.0 to 5.0 PPM according to the API Reef Masters test kit's color chart.
From what I gather, 1 gram of Granular Ferric Oxide per gallon of water only eliminated phosphates by like 0.1 - 0.5 PPM?
So that means I need to use 10 grams per gallon for 1.0 - 5.0 PPM reduction?
Multiply by 100 gallons equals a kilogram for my tank to reduce from 5PPM to zero?
Am I way off here?
