Yeah, real easy. The instructions tell you exactly how much to use per vol to reduce the P04 to the desired level. Worked great for me. I used it for about a month or so until my P04 stopped leaching from the rock and sand, and would stay down. After that, GFO would maintain it, and didn't have to use it again. But it definitely works, if all else fails. I had really high phosphates in one tank, which is why I resorted to that.
Having said that, you P04 is not really high at .15. But if you can't get it down any further with rowaphos, you might want to try the Foz Down (from Tim in Chilliwack). I have never used rowaphos myself, so can't say how effective it is compared to just straight GFO in a reactor. Maybe you need to change it more often, or stir it up between changes.
As for your corals, some SPS are fine with .15 ppm, but others are not, for sure. But I think they will all benefit from lower P04. My SPS, and tank looked best when it was zero or near zero.
