Phosphate is only really bad for the reef as it feeds all PEST algae??
Nitrates and ammonia can be processed by live rock and easily controlled with water changes. Not so with Phosphate.
Apart from being pure algae fuel, it's also a poison to the calcification process in stony corals, drives down pH and Alkalinity, causes browning of coral pigments, and gets absorbed into calcerious substrates in the tanks (sand & rocks). It's also ubiquitous in rish foods and most tap water so it's almost impossible to avoid in a closed system aquarium.
It's nasty stuff, so take steps to eliminate it and the health of your tank will improve.
