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. Review: Works - Great Review: Great - Love this mag works fast. bottle was busted and I emailed and 10 minutes later I got a new one on the way. Great buy ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00L5MNUD6 | | ASIN | B00L5MNUD6 | | Best Sellers Rank | #120,297 in Pet Supplies ( See Top 100 in Pet Supplies ) #1,035 in Aquarium Water Treatments | | Brand Name | ESV Aquatics | | Customer Reviews | 4.7 4.7 out of 5 stars (64) | | Date First Available | June 24, 2004 | | Department | men, women | | Item Form | Liquid | | Item Weight | 1.9 pounds | | Item model number | 0 | | Liquid Volume | 32 fluid ounces | | Manufacturer | E.S.V. | | Manufacturer | E.S.V. | | Manufacturer Part Number | 898636002358 | | Number of Items | 1 | | Pet Type | Fish | | Product Dimensions | 3.3 x 3.3 x 9.8 inches; 1.9 pounds | | Target Species | Fish | | UPC | 898636002358 | | Unit Count | 1 Count | ## Product Details - **Brand:** ESV Aquatics - **Item Form:** Liquid - **Item Weight:** 1.9 pounds - **Liquid Volume:** 32 fluid ounces - **Unit Count:** 1 Count ## Images ![ESV Aquatics B-Ionic Magnesium Liquid Supplement for Coral Reef Salt Water Aquariums, 32 Ounce - Image 1](https://m.media-amazon.com/images/I/51LpOBkGIOL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works *by D***D on January 9, 2022* Great ### ⭐⭐⭐⭐⭐ Great *by M***S on August 4, 2018* Love this mag works fast. bottle was busted and I emailed and 10 minutes later I got a new one on the way.

I rarely use because I get most my MAG from water changes. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/8731336-esv-aquatics-b-ionic-magnesium-liquid-supplement-for-coral-reef](https://www.desertcart.tw/products/8731336-esv-aquatics-b-ionic-magnesium-liquid-supplement-for-coral-reef) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-25*
