The Milwaukee MC720 kit provides complete automation for maintaining stable pH levels in your saltwater aquarium. This comprehensive package includes the MC122 pH controller and the MP810 dosing pump, working together to constantly monitor and precisely adjust pH. Simply establish your desired pH range, and the system automatically doses the necessary solutions to keep your water chemistry consistent, eliminating the need for manual testing and dosing while preventing dangerous pH swings.

The system is engineered for accuracy and reliability, featuring a control range of 5.5 to 9.5 pH with an accuracy of ±0.2 pH. A large digital LCD readout provides clear, immediate results, while audible alarms activate if the pH level deviates from your high or low set points. The kit includes a lab-grade, gel-filled, double-junction pH electrode for low maintenance and high performance, attached via a flexible 6.5-foot cable. The included MP810 dosing pump is specifically designed for this controller, delivering a flow rate of 0.16 GPM at a maximum pressure of 1.5 bar.

This controller and pump kit is ideal for dedicated reef aquarists and those with sensitive aquatic systems who require precise and continuous pH management. It is particularly beneficial for managing calcium reactors or dosing kalkwasser, where stable pH is critical for coral health and growth. By automating this crucial aspect of water chemistry, the MC720 kit allows hobbyists to focus on other aspects of their aquarium, confident that their pH is consistently dialed in for optimal results.
