Automating Reef Tank pH Alkalinity Calcium and Magnesium Control

Automating pH , Alkalinity , Calcium , and Magnesium control is part of a series I am writing about how to automate a reef tank . Reducing the work you need to do to maintain a reef tank .

Dosing pumps automate the delivery of two-part solutions ( calcium + alkalinity ), magnesium , trace elements, and other additives on a precise, repeatable schedule.
Reef Tank Automation

Automated dosing systems and controllers maintain stable levels of alkalinity , calcium , and magnesium vital elements for coral growth. Stability prevents shocking fluctuations that can harm delicate invertebrates.
Discover the five best reef tank auto testers for 2026 and learn how to choose, set up, and maintain automated monitoring and dosing to stabilize alkalinity , calcium , magnesium , and more.

Mastertronic Essential Automated Water Tester (AlkCalMagPO4NO3)
The Mastertronic Essential is a fully automated water testing device designed to measure the five most critical parameters in your reef tank : alkalinity (dKH), calcium , magnesium , nitrate, and phosphate.
Simplify reef tank dosing. Automate alkalinity , calcium , and magnesium dosing, monitor ratios, and optimize stability for a ecosystem.
