Just got a phosphate API test kit and found it to be 1.0. Other tests are:

Ammonia - 0
Nitrite - 0
Nitrate - 10.
KH - 5

I know I can bring it down by water changes, but what besides over feeding would cause it to be this high? I have a 50 gal community tank which I feed twice a day. It seems all is eaten in a few minutes.
