I have a dual chamber MRC calcium reactor for sale. It's been upgraded to fit tanks up to 700 gal. This is a very heavy duty system. I'm finally breaking down my tank to build an aquaponics system. Comes with the dual chamber MRC calcium reactor, FULL C02 tank (filled it up a week and a half ago), regulator, Mag 2 recirculating pump, Maxi-Jet pump, and 3 jugs of media.
This is a top of the line system able to handle up to 700 gal. The dual chamber reactors are better at scrubbing ph. This keeps your ph levels from dropping like they would with a single chamber reactor. The PH probe and controller will keep the ph steady in your reactor. As your media dissolves, alkalinity, calcium and magnesium are dosed into the system keeping levels steady. Currently using this on an sps tank. The system works perfect. $350 Call Dominic 760-703-4197
