The new Nilsen (kalk) Reactors from My Reef Creations provide simple and complete control over kalkwasser dosing. Each of the Nilsen reactors come with a programmable touchpad interface which allows the hobbyist to set mixing timing intervals. The MRC interface can be set in intervals down to the second, giving the hobbyist the ability to customize mixing times to fit their system.

Unlike many other Nilsen Reactors, the MRC reactors feature a heavy-duty external pump (Panworld/Blueline), providing more powerful and reliable performance. The unit requires only one power cord, connected to the LCD display. The pump connects to the control panel with a waterproof connector.

There are currently three models available, small, standard and large. All three models have an 18″ tall chamber, and are 4 1/2″, 6″, and 8″ in diameter, respectively.
