Hanna Phosporus Checker ULR
Test result 114 ppb (Phosphorus) from my shallow 5ft tank containing rocks soak in RO/DI water. Apparently the rocks are still releasing PO4 into the water. :(
Recommended PO4 for SPS tank would be 0 to 0.03 mg/L. Basically need to achieve max reading of 10ppb on my Hanna checker. Still far to go.....
Side by side D-D H2Ocean Phosphate test kit and Hanna Phosporus Checker (ULR - Ultra Low Range).
After reading and research, I managed to obtain formula to convert Phosphorus to Phosphate. Formula as per below:
([Phosporus (in ppb)] x 3.066) / 1000 = Phosphate (in ppm)
Taken my test result as example, it would be 114 x 3.066 / 1000 = 0.349.
