Traditional kalkwasser dosing requires hobbyists to manually mix white powder into large top-off reservoirs or reservoirs. This not only consumes substantial space under the cabinet but exposes the solution to room air, where carbon dioxide immediately reacts with the lime water to form a useless calcium carbonate precipitate crust, rapidly reducing its potency. The IceCap KM-150 completely eliminates manual daily mixing by isolating the calcium hydroxide within an airtight, compact structural tower.\u003c\/p\u003e\u003cp\u003eAt the operational core of the Medium Kalk Mixer is its advanced \u003cb\u003eAdjustable Speed Magnetic Stirrer Motor\u003c\/b\u003e. Standard kalk stirrers use traditional internal water pumps to mix the slurry, which quickly wear down or freeze up as calcium scales form along the impellers. The KM-150 utilizes a completely isolated external motor that drives a heavy-duty internal magnetic stir bar coated in reef-safe polymer. Hooked up to an external timer or controller, the mixer automatically turns on a few times a day to gently agitate the powder bed at the base, creating a highly concentrated, super-saturated fluid layout. When your fresh Auto Top-Off (ATO) pump pushes fresh water into the reactor base, it forces the clear, rich kalk solution out of the top gravity port and down into your sump, providing balanced calcium and alkalinity while maintaining a stable pH level of 8.3 inside your display.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eAggressive pH and Nutrient Support:\u003c\/b\u003e Delivers a high-pH solution that binds free phosphates while neutralizing organic CO2​ inside the aquarium loop to maximize coral growth rates.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eSafe, Non-Pressurized Discharging:\u003c\/b\u003e Employs a zero-pressure gravity flow design that limits structural strain, eliminating the messy floor leaks common with pressurized filters.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eHeavy-Wall Acrylic Engineering:\u003c\/b\u003e Constructed from thick, durable clear cell-cast acrylic panels anchored securely onto a heavy, high-gloss solid PVC support plate.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003ci\u003e(Note: This retail package includes (1) Medium Kalk Mixing Reactor vessel, (1) integrated magnetic drive motor, (1) internal magnetic stir bar, (1) low-voltage power supply, and push-fit plumbing adapters.
