Keep your aquarium water testing accurate and consistent with Hanna Phosphate Low Range Checker Reagents (HI713-25). Specifically designed for the Hanna HI713 Phosphate Checker HC, these genuine replacement reagents provide everything you need to perform 25 phosphate tests, helping you monitor nutrient levels and maintain a healthy aquarium.
Phosphate is an important water parameter in both freshwater and marine aquariums. While small amounts are essential for plant and coral growth, excessive phosphate can contribute to unwanted algae growth and negatively impact water quality. Regular phosphate testing helps you maintain balanced nutrient levels and identify potential issues early.

Why Is Regular Phosphate Testing Important?
Phosphate is one of the key nutrients to monitor when maintaining a healthy aquarium. Excessive phosphate can encourage nuisance algae growth, while insufficient phosphate can limit the growth of aquatic plants and corals.
Regular testing allows you to:
-
Monitor phosphate concentrations and nutrient trends.
-
Evaluate the effectiveness of phosphate-removing filter media.
-
Identify changes caused by feeding, waste and nutrient accumulation.
-
Make informed adjustments to aquarium maintenance and filtration.
When used with the Hanna HI713 Checker, these reagents provide convenient digital phosphate measurements, eliminating the need to interpret traditional colour charts.
Important Compatibility Information
These reagents are specifically designed for the Hanna HI713 Phosphate Low Range Checker HC. They are not interchangeable with the Hanna HI774 Phosphate Ultra Low Range Checker or HI736 Phosphorus Ultra Low Range Checker reagents.
For reef aquariums requiring greater precision at extremely low phosphate concentrations, we recommend considering the Hanna HI774 Ultra Low Range Phosphate Checker instead.
Please Note: This product contains replacement reagents for 25 tests. The Hanna Checker testing device is sold separately.
