Product Description
ESV B-Ionic Magnesium - 32oz
ESV B-Ionic Magnesium - 32oz is a one-component liquid magnesium supplement for marine and reef aquariums. It helps maintain magnesium levels that support stable calcium and alkalinity chemistry for corals, clams, coralline algae, and other calcifying reef organisms.
ESV B-Ionic Magnesium for Reef Chemistry Balance
Magnesium plays an important role in helping calcium and carbonate alkalinity remain available in seawater. When magnesium falls too low, reef aquariums can become harder to stabilize, making this supplement useful alongside B-Ionic Calcium Buffer System, kalkwasser, or other reef calcium and alkalinity maintenance methods.
One-Part Magnesium Support Without Extra Nitrate or Phosphate
- Liquid magnesium supplement for marine and reef aquariums.
- Helps maintain magnesium levels used in balanced reef chemistry.
- Designed for use with B-Ionic Calcium Buffer System or calcium hydroxide.
- Helps support calcium and alkalinity stability in closed marine aquaria.
- Does not contain nitrates, phosphates, organics, or chelating agents.
- Ready-to-use liquid format requires no dry mixing before dosing.
32oz Magnesium Supplement Details
- Package size: 32 oz.
- 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.
- Target range: Dose according to testing to maintain appropriate reef aquarium magnesium levels.
- Use: Marine aquariums, reef systems, coral displays, and calcification support.
Dosing ESV B-Ionic Magnesium
Test magnesium before dosing and add the supplement to a high-flow area of the aquarium or sump. A common adjustment dose is 1.5 ml per gallon of aquarium capacity per day until the desired magnesium level is reached. Make adjustments gradually, retest frequently, and avoid large untested corrections. Keep calcium, alkalinity, and magnesium testing aligned so reef chemistry stays stable rather than chasing one number at a time.
What's Included
