This dose to your 55 gal tank would give 0.88 ppm of PO4. So idk if the test can test that low, anyways test kit are pretty inaccurate. What is your current setup ? (high/low plant mass, Co2 inject, high light or low light, the fish load)

Considering you are doing 50% water change a week, dose 3 capfull more for now then 3 capfull a week. This should give you a cumulative of maximum 2.4 ppm PO4 from fertilisation if you feed the fish a lot you will be a bit higher than this which should be plenty PO4.
