Phosban would be better, because it's iron based. Phosphate sponge will release phosphate back into the water if you leave it in to long. Iron based media will not.
P.S I went to college in Cortland N.Y is between Binghamton and Ithica
Kent Phosphate sponge works but it has a lifespan of about 48 hours before it releases the Phosphate back into the water.. GFO works better, lasts longer, and won't leach.
