It could get quite pricey (I'm thinking in the hundreds of dollars) to use GFO with such high concentrations and large water volumes. It would exhaust quite quickly, necessitating frequent changing.
Seaklear phosphate remover (a product for swimming pools, lanthanum chloride) in a 32 oz bottle removes 3ppm from 10,000 gallons for around $30.
