OCTO KS-100 - KS150 Kalk Stirrer

The Reef Octopus Kalk Stirrer delivers reliable calcium hydroxide dosing with a powerful yet quiet high-torque, low-RPM motor that gently suspends particles while maintaining a clear, saturated solution at the top. Its sealed design with large thumb screws makes refilling effortless—no messy pre-mixing or clogging issues. Unlike traditional powerheads or bulk lime water storage, this compact reactor eliminates space constraints and dosing risks. Salt-water safe construction and quick-connect fittings ensure straightforward integration into your system. Simply set it and forget it for consistent pH stability and alkalinity support. Available in KS-100 and KS-150 sizes to match your tank's calcium demands.
