Product Description
ESV B-Ionic Magnesium - 1 Gallon
ESV B-Ionic Magnesium - 1 Gallon is a larger ready-to-use liquid magnesium supplement for reef aquariums with regular magnesium maintenance needs. It helps support stable calcium carbonate chemistry in marine systems where corals, clams, coralline algae, and water changes affect magnesium levels over time.
Larger ESV B-Ionic Magnesium Supply for Ongoing Reef Dosing
The 1 Gallon size is a practical choice for aquarists who test and adjust magnesium regularly, especially on larger reef aquariums or systems using two-part dosing. It provides more supplement for repeated corrections, ongoing maintenance, and automated or manual dosing routines.
Magnesium Stability for Calcium and Alkalinity Support
- One-component liquid magnesium supplement for saltwater aquariums.
- Helps maintain magnesium levels that support calcium and alkalinity stability.
- Useful with B-Ionic Calcium Buffer System, kalkwasser, or other reef dosing methods.
- Supports reef systems with stony corals, clams, coralline algae, and heavy calcification demand.
- Free of nitrates, phosphates, organics, and chelating agents.
- Ready-to-use liquid format is convenient for regular testing-based adjustments.

- Product type: Liquid magnesium supplement.
- Concentration reference: 36,000 ppm magnesium.
- Effect reference: 1 ml raises 1 gallon of aquarium water by approximately 10 ppm magnesium.

Testing and Adjusting Magnesium Levels
Measure current magnesium before dosing. Add ESV B-Ionic Magnesium to a high-flow area and adjust gradually based on test results. A common adjustment dose is 1.5 ml per gallon of aquarium capacity per day until the target magnesium level is reached. Recheck magnesium, calcium, and alkalinity during the adjustment period, and do not use magnesium supplements as a substitute for regular calcium and alkalinity testing.
