## Overview

The Viaaqua AC10 Acro-Cal Calcium Reactor is a compact, easy-to-install system designed for aquariums up to 75 gallons.

## Description

Product 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. desertcart.com FeatureBuilt-in water pump and bleed valveUse in-sump or hangingEasy twist off top Bubble counter includedBuilt-in water pump Built-in compression fitting for pH sensorDescriptionViaAqua Acro-Cal Calcium Reactor 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.

Review: Easy set-up. - Exactly as described. Works great!! Easy instructions and set-up was simple.
Review: Leaks, internal pump dies within 3 days, unsafe, dagerous! - 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!
