## Overview

The Viaaqua AC10 Acro-Cal Calcium Reactor is a compact, all-in-one solution designed for reef aquariums up to 75 gallons. Featuring a built-in water pump and bleed valve, it efficiently dissolves calcium media using CO2 to maintain stable calcium and alkalinity levels, essential for healthy coral growth. Its space-saving design fits sump or hang-on-back setups, providing continuous buffering and minimal maintenance for a thriving reef environment.

## 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.

*by C***A on 11 November 2018*

It leaks from all connections. Will not function correctly. Fills up with gas, doesn't liberate gas correctly. Runs internal pump dry which breaks and melts with 3 days... Very fiddly if it does work, cannot be adjusted and just left. Dual input of gas and water - REALLY, REALLY BAD DESIGN. DON'T WASTE YOUR TIME OR MONEY!
