Re: phosphates off the scale

my tap water tests ok for phosphates. i feed the fish "dried worms". i'm
thinking maybe there are dead fish in the gravel. i did use ph down
initially and then read that it has phosphates so i stopped. i have done at
least a half dozen water changes since then w/ no effect on the phosphates
levels. the tank is at my office so i can't run tests till monday... thanks
for the response.
