Product Questions

Do I need different reagents for the two different Hannah phosphate checkers?
Question by: James on Sep 15, 2017, 7:49 AM
For the three models of phosphate/phosphorus checkers, HI713, HI717, and HI736, each does have its own set of reagents, associated with the model number. For low level phosphate measuring on a reef tank, we actually recommend using the ULR Phosphorus checker and converting the readings to phosphate, since this has produced the best results in getting good, accurate readings at very low levels.

Happy Reefing!
