I don't have the box in front of me but I don't believe purigen will absorb phosphates, try phosban for the phosphate....
Yup... purigen won't do anything about phosphates. Another minor point... Purigen isn't advertised to get rid of ammonia/nitrites/nitrates DIRECTLY. It's advertised to remove the stuff that creates ammonia/nitrites/nitrates, which it seems to do quite well. But don't expect it to suck up your existing nitrates, but it will keep things from getting worse.
