I used to think I had 0 phosphate or close to that with standard test kits (e.g. Salifert), then I got the Hana Checker. It showed that I had 0.1 ppm! I always had algae problems and coral RTN/browning. Then I got some GFO and biopellets. I managed to get a reading of 0.04 with the Hana Checker. I think 0.07 is a bit high and may cause you algae issues. I still have trouble eradicating all my red cyanobacteria and bryopsis.
