Hanna Phosphate ULR Checker

The Phosphate ULR Checker is a pocket colorimeter for marine and reef tanks that reads very low phosphate levels, from 0.00 to 0.90 ppm. High phosphate feeds algae and lowers dissolved oxygen, so it pays to catch it early. One fresh battery lasts at least 5,000 tests, and the kit comes in a plastic carry case.
