IceCap Kalk Mixing Reactor – Small

The IceCap Kalk Mixing Reactor – Small is a dedicated kalkwasser reactor for mixing calcium hydroxide solution and delivering saturated kalkwasser to reef aquariums through an ATO system or dosing pump. Its compact footprint, magnetic mixer, quick-fill cap, and sealed reactor chamber help automate kalkwasser mixing while reducing the need for frequent manual stirring.

Small IceCap Kalk Reactor Overview

This small IceCap Kalk Mixing Reactor is rated for aquariums up to 100 gallons and is designed to mix kalkwasser inside a sealed chamber before it is delivered to the aquarium. The magnetic mixer eliminates the need for a powerhead inside the reactor vessel, while the removable chamber and quick-fill cap make kalkwasser replenishment and service more practical for routine reef maintenance.

Kalk Mixing Reactor Features

• Dedicated reactor for mixing calcium hydroxide kalkwasser solution for reef aquariums.
• Adjustable speed magnetic mixer helps maintain concentrated kalkwasser without an internal powerhead.
• Sealed airtight chamber helps preserve kalkwasser solution potency.
• Quick-fill cap allows cleaner kalkwasser powder addition during maintenance.
• Reactor vessel detaches from the base for easier cleaning and service.
• Push-fit tubing connectors simplify integration with compatible ATO or dosing systems.
• Gravity drain design supports reliable delivery from the reactor to the aquarium.
• Compact profile fits more easily under many aquarium stands and cabinets.

Kalk Reactor Compatibility Notes

The IceCap Kalk Mixing Reactor – Small requires a compatible ATO system or dosing pump, calcium hydroxide kalkwasser powder, and a timer or controller, which are sold separately. The reactor is not submersible. The mixing motor is not intended for continuous operation and should be set to mix periodically. Use slow kalkwasser delivery and monitor pH, alkalinity, calcium, and overall reef stability.

Setting Up the IceCap Small Kalk Reactor

Connect the reactor to a freshwater reservoir using a compatible ATO unit or dosing pump, add kalkwasser powder through the quick-fill cap, and connect the mixer motor to a timer or controller for periodic mixing. Freshwater entering the reactor pushes saturated kalkwasser solution out to the aquarium. Replenish kalkwasser powder as needed, rinse the vessel during regular service, and inspect the mixer friction bands during maintenance.
