Please help clarify my Phosphate levels in reef

[xdcbenoitxd]

Hi I am hoping for some insight from someone who has been in the hobby longer than I have. I was struggling with ridiculously high phosphates which caused superb amounts of hair algae and incorporated some GFO into my maintenance regimen. I have since upgraded my test kit with a Hanna ULR phosphate checker. I reached what I believed were target phosphates 0.03-0.05 ppm but didn't realize that the checker was in ppb. The hair algae is disappearing and my LPS are looking great to me as long as I add some nitrates (can't seem to keep those up). So what I want to know is are these levels too low for long term health of my LPS?

Thanks

With the error range of tests considered, I think 0.03-0.1ppm is fine (I forget the ppb) conversion. You can have it lower, but need daily feeding. I don't like running lower than that as dinos seem to correlate with sustained 0.00ppm phosphates.

0.03-0.05 ppm is the target parameter for LPS 0.00 is not good as some phosphate is needed. 0.05 ppm is the equivalent to 50 ppb and I am testing at 0.05 ppb
