OCTO Kalkwasser Reactor KS-100

Reef Octopus OCTO Kalkwasser Reactor KS-100 carries a high torque low RPM motor that effectively, silently and gently mixes your calcium hydroxide (Kalkwasser). This method is not only ideal but is also the safest way of dosing the freshest possible Kalkwasser to your reef system. The OCTO Kalkwasser Reactor KS-100 is designed to keep the undissolved particles at the bottom of the reactor chamber while always leaving the clear highly saturated Kalkwasser liquid at the top. Adding Kalkwasser powder couldn’t be easier with just a few twists of the large thumb screws releasing the seal-tight lid for quick and easy Kalkwasser refills.

No need for powerheads that randomly need to be cleaned or replace and no more risky dosing with large vats of lime water which take up valuable space. You will never have to worry about premixing or clogs again when using our new innovative and efficient Kalkwasser Reactor which are extremely easy to use and salt-water safe, making them simply the most economical and best Kalkwasser reactor out there.
