Found this for you:

Post #51 has a conversion.

P-PO4 is the Phosphorous concentration derived from Phosphate, PO4 is the Phosphate concentration.

Personally I stick to PO4.

Actually, having thought about it, the conversion in the post looks a tiny bit wrong to me. The ratio between ppm P-PO4 and ppm PO4 should be the ratio between their molecular masses (3.0661), not the ratio used in the RS table. The difference is trivial mind you (5.44ppm PO4 = 1.77ppm P-PO4 vs 1.81ppm shown in the table).
