## Overview

The Viaaqua AC10 Acro-Cal Calcium Reactor is a compact, efficient solution designed to maintain optimal calcium and alkalinity levels in reef aquariums up to 75 gallons. Featuring a built-in water pump and bleed valve, it ensures consistent water circulation and easy maintenance. By using CO2 to dissolve calcium media, it stabilizes pH and carbonate hardness, promoting healthy coral growth with minimal intervention.

## Description

ViaAqua® Acro-Cal™ Calcium Reactor AC 10 offers a simple and convenient solution for maintaining calcium and alkalinity in your reef tank, both being the backbone to a successful thriving reef environment. How does it works? CO2 is used to lower the pH in the reaction chamber. When the PH is lowered to 6.5-6.8 the circulating water and low pH begins to break down the media creating effluent water that is saturated with carbonates and calcium that continuously drip back to the aquarium. After the initial setup, the calcium reactor requires minimal maintenance. A calcium reactor is almost a necessity for tanks heavily stocked with stony coral, where calcium and alkalinity demands are high and will promote coral line algae growth. Acro-Cal™ Calcium Reactor provides a steady of calcium by using CO2 to dissolve media in the reactor and, thus, releasing calcium into your water. The effluent released also acts as a buffer to stabilize kH.
