Reef Octopus 140mm Diameter Kalkwasser Reactor for Aquariums

The Reef Octopus KS-150 Kalkwasser Reactor (which has a 140mm diameter body, is rated for aquariums up to 800 litres. The reactor chamber itself has an approximate capacity of approximately 11.7 litres) of water. 

Features and Benefits

• Silent, High-Torque Mixing: A low RPM motor gently and effectively stirs the calcium hydroxide (kalkwasser) powder with freshwater, creating a consistently saturated solution.
• Automatic Dosing: Designed to be a sealed, inline system, it connects to an auto top-off (ATO) or dosing pump to automatically dose fresh kalkwasser into the aquarium, preventing exposure to air, which maintains potency.
• pH Stability: Dosing kalkwasser helps elevate and maintain a stable, high pH level (near 8.3) in the aquarium, which is beneficial for coral growth.
• Calcium and Alkalinity Supplementation: It is an effective and economical way to supplement balanced amounts of calcium and alkalinity, which are crucial for the skeletal growth of corals.
• Phosphate Control: The high pH of the solution helps precipitate phosphate, effectively removing it from the water column and helping to control nuisance algae.
• Ease of Use: Features a seal-tight lid with large thumb screws for easy and quick refills of kalkwasser powder.
• Durable Construction: Made from high-quality, heavy-duty cast acrylic.
• Safety: The controlled, automatic dosing through an ATO system minimizes the risk of dangerous pH swings that can occur with manual dosing. 

Specifications

• The high-torque, low RPM motor should be run on a timer for short intervals (e.g., 10-15 minutes every 2 hours) and not continuously, to avoid premature failure.
• The reactor uses a sealed chamber design with a tight-fitting lid to prevent atmospheric CO2 from degrading the kalkwasser solution.
• It requires an external auto top-off (ATO) pump or dosing pump (sold separately) to feed freshwater into the unit and push the saturated solution into the aquarium
