## Overview

ESV Aquatics B-Ionic Magnesium Liquid Supplement is a high-concentration (36,000 ppm) magnesium formula designed to maintain optimal magnesium levels (1350 ppm) in saltwater reef aquariums. It enhances calcium saturation and alkalinity stability by buffering pH without introducing harmful nitrates or phosphates. Easy to dose and fast-acting, it ensures a balanced ionic environment critical for coral health and vibrant reef ecosystems.

## Description

Through the chemical process known as "ion-pairing", magnesium ion concentration influences the saturation point for calcium corbonate in solution. In general, the further the magnesium concentration drops from natural seawater levels (1350 ppm), the more difficult it becomes to maintain adequate levels of both calcium and alkalinity. Magnesium also plays an important role in stabilizing pH by interacting with the buffer system of seawater. B-Ionic Magnesium is an easy to use one component liquid supplement which, when used with B-Ionic Calcium Buffer or kalkwasser, will not disrupt the ionic balance of closed marine aquaria. B-Ionic Magnesium does not contain nitrates, phosphates, organics, or chelating agents. B-Ionic Magnesium contains 36,000 ppm magnesium, and one mL will raise one gallon of aquarium water by 10 ppm.

## Features

- Magnesium is the third most abundant ion in salt water and essential for coral and reef aquaria.
- Magnesium provides buffering capacity by bonding with carbonate ions.
- Because magnesium is binding up carbonate, it allows for more carbonate in the water than if magnesium wasn’t there
- ESV Bionic Liquid Magnesium Supplement safely raises the magnesium level of any marine system and when magnesium levels are appropriately high, it allows for the addition of calcium without the associated drop in alkalinity.
- The B-Ionic magnesium liquid supplement stabilizes the PH levels by interacting with the buffer system and does not contain any nitrates and phosphates
