ESV Aquatics B-Ionic Magnesium is a convenient, one-component liquid supplement designed for saltwater reef tanks

This clear, easy-to-dose formula supports the delicate chemistry that keeps corals coloring vividly and growth steady, without complicating your routine

With its focus on balanced ion work, it helps maintain stable water chemistry while you build a thriving reef ecosystem

Why magnesium matters in reef aquariums Magnesium is the third most abundant ion in natural seawater and plays a central role in reef systems

It helps stabilize the carbonate buffering system by binding with carbonate ions, which in turn makes more carbonate available for corals to build skeletons

Maintaining magnesium at appropriate levels supports calcium uptake and helps keep pH steady in a closed system, contributing to a more predictable, resilient reef environment

In practical terms, magnesium acts as a chemistry facilitator in your tank

A steady magnesium presence supports corals in drawing the carbonate they need, while helping to maintain a stable pH environment, which contributes to a more reliable reef experience over time

Product highlights One-component liquid supplement—simple to use and measure without mixing multiple products Contains 36,000 ppm magnesium to support coral reef systems Does not contain nitrates, phosphates, organics, or chelating agents Helps raise magnesium levels safely, enabling calcium additions when desired Magnesium buffers the water by interacting with carbonate ions and supporting a stable buffer system When magnesium is appropriately high, it enables calcium intake without an accompanying drop in alkalinity Safe to use with B-Ionic Calcium Buffer or kalkwasser, helping maintain ionic balance in closed systems One milliliter raises one gallon of water by about 10 ppm, ing precise dosing control Usage tips and practical considerations Plan dosing around your target magnesium level and routine water changes; dose by measurement rather than guesswork Dosing example: 1 mL per gallon raises magnesium by ~10 ppm, making incremental adjustments easier to track Pair with B-Ionic Calcium Buffer or kalkwasser to maintain balance in reef tanks ESV Aquatics designed B-Ionic Magnesium to fit seamlessly into a reefkeeper’s routine, avoiding unnecessary additives and supporting straightforward maintenance

While this product can help support magnesium levels and the broader ionic balance, results depend on tank specifics such as stocking, feeding, and existing water chemistry

This approach helps reef enthusiasts pursue a stable, vibrant environment for their corals and invertebrates without overhauling established habits
