Red Sea MCP Phosphate Test Kit

Red Sea MCP Phosphate Test Kit

Red Sea MCP Phosphate Test Kit is a colorimetric phosphate test kit for marine aquariums, giving a quick and reliable reading of phosphate (PO4) in your tank water. It suits saltwater hobbyists who want to keep an eye on nutrient balance and who need a measurement accurate to 0.1ppm PO4.

Key Benefits

• Quick, user-friendly colorimetric test that measures phosphate (PO4) in your marine aquarium
• Accuracy of 0.1ppm PO4, so small changes in phosphate can be picked up
• Wide testing range of 0-17ppm
• Enough for 100 tests per kit
• Works alongside Red Sea's Nitrite/Nitrate test kit to help you balance NO3:PO4 when dosing NO3:PO4-X (Biological Nitrate and Phosphate reducer)

How to Use

The kit supplies everything needed to run the test: two reagents, a 10ml syringe and a glass vial. Results are read against the included colour card. Follow the step-by-step instructions in the user manual supplied with the kit.
