I have emailed Aquasafe but have not had a reply yet.

Have you tested phosphates before and after going through the the rodi? If "xerxes300" chimes in here he may be able to tell you exactly what the current GVRD phosphate reading is from our tap water. It should be in line with what Myka found on the city website. Is your rodi new? Filters new? Could be stagnant water inside the unit?
If you're looking to lower phosphates in general within your tank I had good success with the liquid phosphate removers ("Fozdown" or "Phosphate Solution"). I tried GFO at one point but didn't like it, mostly just more work than adding a few drops here and there
