Equipment Used: Hanna Phosphate ULR Checker
Range: 0.00-0.90
Note: This is a very tight scope but is very accurate within that range, which is why we use this Checker for Phospahtes, particularly on a Reef Tank. Many FOWLR, Anemone Systems, etc may always run at levels beyond the max capacity of this meter and not experience issues because of it. This is very different than the more simple dropper test kits, which are often only reactive as anything over a 0 reading around 0.25, and 1.0 still being a fairly low reading.
