    • Awesome reactor. By Brian on 4/6/2014

      This is my first Calcium reactor so I don't have a lot to compare it to.
      I bought the electronic regulator , Milwaukee PH controller, ARM extra course media and Zeo Mag.
      If you have a Hanna Alk checker it will make dialing it in much easier as you can see small up/downs in the alk easier than with a drop test kit.
      It's been a few months now and I believe my tank is so much more stable. I would say i have a medium SPS load and the PH barely blinks from night to day. The dual reactor I'm sure helps a lot.
      I still have my dosing pumps that sit in standby but haven't really needed them. I much prefer the reactor since I don't have to mix up anything.
      Fittings and quality are all top notch. I would put a rubber pad under the pump so it doesn't have any hum noise.
      Also order a couple of extra PH calibration fluid packs.

    Awesome question! I would definitely recommend the Sicce Synchra Silent 0.5 in think link below. :-)
