Hannah phosphate checker

[Bigwrasse]

Im looking to purchase a Hannah Phosphate checker because I currently use the Red Sea and the test takes a while and doesn't seem very accurate. Do you recommend the low or Ultra low checker?

ULR is for <1 ppm (ULR Phosphorus .6 ppm Phosphate max or ULR Phosphate Checker .9 ppm Phosphate max). If you keep phosphates higher than that, then don't go with ULR. If I have phosphate problem and ULR isn't high enough to read, I will go with simpler-cheaper Salifert tests until back where I want.

The new hanna HI774 is the one you want for a reef...
