Reef Octopus KS150 Nilson Kalk Reactor

The Reef Octopus KS150 Nilsen Kalkwasser Reactor steps up chamber capacity from the KS100 for reef systems dosing more kalkwasser per day. The same high-torque, low-RPM motor gently stirs calcium hydroxide, keeping undissolved powder settled at the bottom while clear, saturated kalkwasser stays ready at the top.

• Best for: reef systems with higher daily kalkwasser dosing needs than the KS100 covers
• Motor: high-torque, low-RPM stirring motor, not intended for continuous running
• Design: large thumb screws for quick lid removal and kalk powder refills, seal-tight closure

The larger chamber means fewer refills per week for tanks running a heavier auto-top-off kalkwasser dosing schedule.

Compatible replacement parts: stirring motors and lid seals for the KS150.
