    1) Knop C calcium reactor comes mounted to a bottom/back board (standard). Comes with Eheim re-circulation pump, all tubing. Bubble counter is there but the ports are broken so it should probably just be replaced (cheaply I'm sure). I am also including a dual guage CO2 regulator with solenoid...

  7. Do It Yourself
    This is something I am looming to do for a couple reasons: 1. Cost- the cost of this reactor was extremely high, and it's just sitting catatonic in my basement. The cost of a calcium reactor, goes without saying is high. 2. Size- the chamber of this reactor will hold approx 25 lbs of media...

    Trying to decide on using a calcium reactor again or going with the dosing method. I like the idea of having things controlled by way of dosing, but I also like the cost savings of a calcium reactor. I can't decide. Water volume will be 200 gallons. Tank will be SPS dominant. Thoughts???
