Red Sea MCP pH Alkalinity Test Kit

Red Sea MCP pH Alkalinity Test Kit

The Red Sea MCP pH Alkalinity Test Kit is a dual test kit for monitoring pH and KH (alkalinity) in marine aquariums. It pairs an accurate titration test for KH with a colorimetric test for pH, so saltwater hobbyists can keep an eye on two essential water parameters with one kit.

Key Benefits

• Two tests in one kit: a colorimetric pH test and a titration KH/alkalinity test
• KH titration test with an accuracy of 1 dKH / 0.36 meq/L
• pH test covers 7.6 to 8.6 with an accuracy of 0.2
• Supports accurate dosing of Red Sea KH buffer supplements in fish-only systems
• Enough reagent for 100 pH tests and 55 KH tests
• Supplied with a glass vial, a 5 ml syringe and two colour cards for reading pH results

How to Use

The pH test is colorimetric, so you read the result by comparing the colour against the supplied colour card. The KH test is a titration, so you measure the reagent with the syringe until the result is reached. Full step-by-step instructions are in the included user manual.

Suitable For

• Marine fish aquariums
• Saltwater hobbyists who want to track pH and alkalinity regularly
• Aquarists who dose a KH buffer supplement and want to dose it accurately

Compatibility

The kit is designed for marine aquariums. It lets you dose Red Sea KH Coralline Gro or Red Sea KH/Alkalinity Foundation B buffer supplements accurately in fish-only systems.
