## Overview

The IceCap Kalk Mixing Reactor KM-120 is a compact, durable reactor designed for aquariums up to 100 gallons.

Its solid PVC and acrylic construction, easy maintenance design, and airtight environment ensure reliable, mess-free operation that supports vibrant reef ecosystems.

## Description

Simplify & automate the addition of calcium hydroxide with the IceCap Kalk Mixer! The IceCap Kalk Mixer is a dedicated reactor for mixing calcium hydroxide (Kalkwasser) solution to ensure maximum concentration with each dose to your aquarium and eliminates the need for frequent manual mixing. A clever magnetic mixer means no more pesky powerheads to clean and replace frequently. The intelligent design makes maintenance a breeze and the slim profile allows for easy placement under your tank and integration with your existing ATO system. Features Adjustable speed magnetic mixer Solid PVC and acrylic construction Compact profile easily fits under your tank Reactor vessel detaches from base for easy maintenance Push-fit tubing connectors Convenient quick-fill cap for mess free Kalkwasser addition Sealed airtight environment preserves solution potency Gravity drain design ensures reliable performance Benefits Using Kalkwasser to supplement the aquarium with calcium and carbonates is one of the most efficient and economic methods and has been used successfully on reef aquariums for many years. The Kalkwasser powder is relatively inexpensive, is super concentrated and can simply be mixed into your top-off water. Additionally, the elevated pH of the resulting kalkwasser solution and CO2 reducing properties help to maintain a more desirable and stable pH of 8.3 inside your tank.

Review: Absolutely love it! - This kalk reactor is amazing. I bought a smart outlet to turn it on for 1 minute every 4 hours, and a Kamoer X1 Pro 2 to dose 125 ml every hour. It's working like a charm to keep my pH up and adds some calcium and alkalinity to supplement my calcium reactor. My acropora are rewarding me with some serious polyp extension due to the higher pH.
Review: Refurbished sold as New - I paid for a new unit and received one that was not new as it had no instructions in the box and several ties were untied and laying in the bottom of the box plus you could see the box had been taped over twice.

### ⭐ Bad design
*by A***R on August 18, 2022*

Well being brand new the magnet wont turn solution. I had to do manually for 2 days until i got timer. So i would turn it on for a minute. Wait 15 minutes turn back on nothing. You can hear it. So i did again for a few days and same thing. So im sending back and purchasing one with a stirring paddle
