Skimz has now introduced their mini calcium reactor line with the Monzter CM93 Duo internal calcium reactor. With most standard calcium reactors you will need a dedicated feed pump which can malfunction and clog causing inconsistent flow rates through the reactor. With the CM93 Duo reactor the circulation pump does double duty as a feed pump making adjustments that much easier. With a specially designed inlet to the reactor fresh tank water is pulled into the reactor at the rate the effluent is allowed to exit while recirculating the water within the reactor to contact as much reactor media as possible. With the DC pump the RPM of the pump can be controlled for fine tuning.
