ESV Aquatics B-Ionic Calcium Buffer System — 2-Part Calcium & Alkalinity Maintenance Kit for Saltwater Reef Aquariums (2-Gallon)

Introducing the B-Ionic Calcium Buffer System from ESV Aquatics — a two-component liquid supplement designed for reef keepers seeking reliable calcium and alkalinity management without the complexity of powder blends or calcium reactors.

Why choose B-Ionic? The system uses equal parts of two ready-to-use liquids (Part A and Part B). When mixed in the recommended way, it supports calcium and carbonate alkalinity at the levels reef organisms require to calcify, while preserving the delicate ionic balance of your saltwater aquarium. The formulation is phosphate- and nitrate-free, so it cleanses the pathway for coral growth without adding unwanted nutrients.

What makes it practical for daily use? You’ll dose a simple daily amount—starting at 1 ml per 4 gallons of water—to keep pace with natural uptake and skimming-related losses. The two bottles are concentrated and must be diluted with RO/DI or distilled water before use, so you can tailor the strength to your system with minimal mess.

What else comes with B-Ionic? The kit not only provides calcium and carbonate alkalinity but also includes a balanced mix of major, minor, and trace elements in the proper ratios to mimic natural seawater chemistry. This helps restore ions that can be depleted in some setups and supports stable water chemistry over time.

Key benefits at a glance

• Two-component liquid system that eliminates powder mixing and reduces risk of ionic disruption.
• Maintains calcium and alkalinity while avoiding organic additives, phosphates, or nitrates.
• Supports ionic balance by replenishing a broad spectrum of ions that coral and other reef inhabitants rely on.
• Simple, concentrated formula designed for reef tanks of varied sizes; compatible with common protein skimmers.

Versatility and use cases

• Ideal for hobbyists seeking a reliable alternative to calcium reactors and other supplementation methods.
• Suitable for chronic carbonate alkalinity maintenance and calcium supplementation in mixed reef systems.
• Supports colorful growth and healthy polyp extension by providing necessary ions in balanced proportions.

Notes for use and compatibility

The kit includes two 1-gallon bottles (Part A and Part B). For best results, dilute each component with RO/DI or distilled water as directed before adding to the aquarium. Regular dosing aligned with your tank’s bioload and protein skimming helps keep ionic balance steady and can complement routine water changes.
