Marine Phosphate Checker HI-713 – Hanna

Product details

Marine Phosphate Checker HI-713 – Hanna is a handheld test kit designed to measure phosphate levels (PO4) in marine/reef aquarium water. Phosphate is an important water-quality parameter because it can influence algae growth and overall system stability. In practical use, you compare the color change produced during the test with the checker’s readout to get a numerical phosphate result, helping you track trends and guide phosphate-reduction or monitoring decisions.

Features:

• Built for marine aquariums with a dedicated phosphate (PO4) test workflow
• Colorimetric measurement approach for converting a sample color change into a numeric reading
• Useful for routine monitoring to help identify rising or falling phosphate trends over time
• Helps support water-management decisions alongside other core parameters during aquarium troubleshooting
• Hanna HI-713 checker format is intended for consistent testing for repeatable results
