Controlling phosphate and nitrate is foundational to reef health—elevated nutrients drive nuisance algae growth, suppress coral coloration, and indicate issues with skimming, feeding, or biological filtration. The Hanna Instruments Algae & Nutrient Management Kit addresses both parameters in a single purchase, combining the HI774 Ultra Low Range Phosphate Checker and the HI782 High Range Nitrate Checker in one box. Each unit uses Hanna's proven colorimetric method to deliver a precise digital reading, removing the guesswork that comes with liquid drop kits or paper-based color charts.
The HI774 is calibrated for the phosphate concentrations that matter most in a reef environment. With a measurement floor of 0.01 ppm, it can detect the kind of small nutrient creep that precedes algae blooms long before a visual chart would register a meaningful color shift. For SPS-dominated systems where target phosphate often sits between 0.02 and 0.08 ppm, this resolution is genuinely useful rather than just a marketing specification.
The HI782 covers nitrate across a wider range—up to 75 ppm—making it appropriate for new tanks cycling through higher nutrient phases, mixed reef or FOWLR systems, or any situation where nitrate swings are expected. The digital readout reduces test-to-test variability and makes it easy to track trends over time when results are logged consistently.
The kit includes 25 reagent tests for each checker, along with cuvettes, caps, and batteries. This is enough to establish a baseline testing routine and identify problem trends before ordering additional reagent packets. Both checkers are self-contained and require no external power source, making them straightforward to use at the tank or to bring to a local fish store for a water-comparison test.
Overview
Test. Know. Adjust.

- Digital readout replaces unreliable color-chart comparison
Nitrate — High Range Coverage
- HI782 reads nitrate up to 75 ppm
- Covers cycling tanks, FOWLR, and mixed reef systems
- Consistent digital results support trend tracking over time
Ready to Test Out of the Box
