ESV B-Ionic Calcium Buffer System

B-Ionic Calcium Buffer System

Overview

Maintaining calcium and alkalinity levels in reef aquariums shouldn’t be complicated. The B-Ionic Calcium Buffer System is the original ionically balanced 2-part system that makes dosing simple and effective. Designed as an economical alternative to calcium reactors, this ready-to-use solution helps aquarists maintain stable calcium and alkalinity without mixing powders, disrupting ionic balance, or adding unwanted organic chemicals.

In addition to providing highly concentrated calcium and carbonate alkalinity for coral calcification, the formula is enriched with major, minor, and trace elements in the correct seawater ratios. This ensures not only healthier coral growth, but also restoration of ions lost during protein skimming—supporting a balanced and thriving reef ecosystem.

Key Features

• 2-Part Balanced System – Supplies both calcium and alkalinity in one complete solution.

• Ionically Balanced – Formulated to maintain ionic equilibrium in marine aquariums.

• Supports Coral Calcification – Provides essential calcium and carbonate alkalinity for growth.

• Comprehensive Mineral Supplementation – Replenishes major, minor, and trace elements.

• Restores Ionic Balance – Replaces ions stripped out during protein skimming.

• Economical Alternative – Easier and more cost-effective than calcium reactors.

• Ready-to-Use or Concentrated Options – Flexible for both small and large systems.
