Unlike traditional methods that require large, open vats of limewater, the KS150 utilizes a high-torque, low-RPM motor to gently stir calcium hydroxide (Kalkwasser). This process keeps the solution fresh and potent by minimizing exposure to air, which otherwise degrades Kalkwasser’s efficacy.\u003c\/p\u003e\u003cp\u003eDesigned for aquariums up to 210 gallons, the Reef Octopus KS150 helps maintain high pH levels while simultaneously precipitating phosphates. The reactor's innovative design ensures that undissolved particles remain at the bottom of the chamber, allowing only the clear, highly saturated liquid to be dosed into your sump. With its solid construction and 1\/4-inch quick-connect fittings, this Nilsen-style reactor is a robust and economical addition to any advanced reef filtration setup.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cp\u003e• \u003cb\u003eSilent Motorized Stirring:\u003c\/b\u003e Features a high-torque motor that rotates mixing blades at a slow speed to prevent stratification. \u003cbr\u003e• \u003cb\u003epH Stabilization:\u003c\/b\u003e Effectively raises and stabilizes aquarium pH levels while providing essential minerals. \u003cbr\u003e• \u003cb\u003eAirtight Design:\u003c\/b\u003e Keeps Kalkwasser fresh by preventing atmospheric CO2 from reacting with the solution. \u003cbr\u003e• \u003cb\u003eEasy Refills:\u003c\/b\u003e Large thumb screws allow for quick access to the seal-tight lid when adding fresh kalk powder. \u003cbr\u003e• \u003cb\u003eDurable Construction:\u003c\/b\u003e Built with heavy-duty acrylic and PVC components for a long service life in marine environments. \u003cbr\u003e• \u003cb\u003ePhosphate Binding:\u003c\/b\u003e Helps precipitate phosphates out of the water column as part of the dosing process.\u003c\/p\u003e\u003ch3\u003eIdeal For\u003c\/h3\u003e\u003cp\u003e• Mixed reef and SPS-dominant aquariums requiring stable calcium and alkalinity levels. \u003cbr\u003e• Hobbyists struggling with chronically low pH levels who want an automated solution. \u003cbr\u003e• Systems where floor space is limited and large limewater reservoirs are not practical. \u003cbr\u003e• Advanced aquarists use a controller or timer to manage precision dosing intervals. \u003cbr\u003e• Aquariums up to 210 gallons that need a cleaner alternative to two-part dosing.\u003c\/p\u003e\u003cp\u003e\u003cem\u003e*The Kalk Stirrer uses a 20W motor that has a lifetime of about 1500 hours.
