KM-120 Magnetic Kalkwasser Mixing Reactor
No More Broken Stir Bars or Replacing Expensive Mixing Pumps!
Kalkwasser is one of the oldest and reliable ways to add calcium and alkalinity from a single solution and using a reactor makes the addition of a kalkwasser solution easier. The IceCap KM-120 Magnetic Kalkwasser Reactor uses a magnetic stirrer to accomplish the mixing of the solution, which means you will never have to clean or replace an expensive mixing pump ever again, and also cuts the maintenance down to bare minimums.

Perfect for Reef Tanks Up To 100 Gallons
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. The use of the IceCap Kalk Mixer will ensure maximum concentration with each dose to your aquarium and reduce the need for frequent manual addition and mixing of the solution.
How Does it Work?
Simply connect the IceCap Kalk Mixer to any freshwater reservoir with the use of an Auto Top Off unit or dosing pump. Kalkwasser powder is then added to the mixing chamber via the handy quick-fill cap. The adjustable speed motor should then be attached to a timer or controller and set to periodically mix the solution inside the reactor a few times per day. When freshwater is pumped from your ATO reservoir into the reactor, the freshly mixed and highly concentrated Kalkwasser solution is pushed out and into your aquarium. When adding kalkwasser to any aquarium, it is best to use a pump with a slow flow rate. Due to the high pH of the solution, you must add kalkwasser slowly and in small amounts, typically multiple times per day. Most ATO systems on the market will fit the flow rate needs of the reactor very nicely because of the small and frequent dosages of freshwater.
What is needed to get a Kalkwasser Reactor Running?
Probably the most obvious things are going to be the reactor and some high-quality kalkwasser. There are a few things that are not as obvious though which are listed below and not included with the Ice-Cap KM-120 Magnetic Kalkwasser Reactor.
Kalkwasser - This is the part that is actually going to be going into your aquarium and we highly suggest using a high-purity kalkwasser solution. Many kalkwasser supplements on the market today have impurities and high amounts of aluminum in them, which can be harmful to your reef tank. Especially when it comes to using kalk in a reactor the higher the grade will mean longer intervals required between maintenance and longer-lasting equipment.
A Slow Flow ATO System - In most cases, a simple low-flow pump and a timer will be a great solution to an ATO system but there are a few others on the market that use optical eyes and float valves that work great. Kalkwasser has a high pH and if added to fast or too much at once could cause the pH of your aquarium to raise over desired levels. The ATO system will essentially plug into the input side of the reactor and push the water through the settled kalkwasser solution allowing the clear amount at the top to flow into your aquarium. A couple of good ATO system is a BRS 50mL Doser and a digital timer (or aquarium controller) or a Tunze Osmolator which can have the pump's flow adjusted by opening the controller housing and simply turning a screw.
Drain Tubing - The IceCap Magnetic Kalk Reactors uses a 1/4" push-connect fitting that can be connected to traditional RO style tubing. With Kalkwasser solutions we like to use a clear or natural line to see any potential clogs forming, however many reefers do like to use a colored tubing for easy identification of the solution inside.
Digital or Analog Timer - The magnetic stirrer that is included in the base will need a power source, and using a simple timer or aquarium controller system, you will be able to control when the solution is mixed. We highly suggest a digital timer if you do not use a controller, but an analog timer can work for telling the reactor to mix the solution a few times a day. To keep the kalkwasser solution mixed properly, just run the magenetic stirrer for a minute or two 3-4 times a day. We suggest trying to keep the mixing to a minimum, and avoiding dosing during or immediately following a mixing cycle.
Footprint - 5.7" x 5.7"
Height - 25"
Body Diameter - 5"
Total Volume - 1 Gallon (approx)*
Input Tubing Size - 1/4" O/D (RO Style Tubing)
Output Fitting Size - 1/4" Push-Connect
*Note: Reactor should not be completely filled with kalkwasser powder. Kalkwasser should be added based on the evaporation rate of the system and the refill interval. We recommend a 2 week interval for service and refills and that the reactor should not be filled more than approximately 25-30% full.
