Filling the Reactor

 • Remove the top flange of the chamber by unscrewing the nylon screws.
 • Place one of the foam pads in the bottom of the chamber on top of the acrylic plate.
 • Gently pour the reactor media into the chamber, covering roughly ¾ of the chamber height.
 LARGE GRADE mEDIA mUST BE USED IN ALL OF OUR CALCIUm REACTORS.
 • Pour tank water in chamber 1 up to the flange. Make sure you have the pump connected, as well as the bubble counter hoses. If not, water
will leak onto the floor.
 • Place the rubber o-ring on to the lower flange.
* If Dual reactor, repeat for chamber 2.
 • Using the thumbscrews install the top flange, tighten tightly to prevent water leakage, but not so much that it strips the threads. When in use,
if water leaks at the top of the screws, tighten more. Use only hand pressure and tighten in a star pattern. We also recommend using silicone
grease to keep the o-ring from binding and to retain life.

NOTE :
BECAUSE THIS IS A REVERSE FlOW CAlCIUM REACTOR WITH A HIGH FlOW PUMP, YOU MUST PUT THE
SPONGE SCREEN ON TOP OF THE MEDIA. FAIlURE TO DO SO WIll CAUSE THE MEDIA TO RISE INTO THE INTAKE AND
THEN INTO THE PUMP, WHICH WIll CAUSE THE PUMP TO SEIZE AND BURN UP.

Filling the Bubble Counter

With the John Guest fittings off, fill the bubble counter with fresh water. Thread the fitting back on and attach the CO2 tubing.

CO2 Installation

After getting your CO2 cylinder filled, keep the main valve located at the top
of the aluminum cylinder OFF (turned clockwise).
  • Attach the dual gauge regulator, and tighten securely, using a teflon
gasket.
  • The gauge on the left reads CO2 in the cylinder
(psi, pounds per square inch).
  • The gauge to the right reads the pressure of the gas leaving the regulator.
  • Attach the tubing supplied to the regulator.
  • The other end goes to the John Guest fitting going into the bubble counter.
  • Close the needle valve (completely turn clockwise).
  • Slowly open the main cylinder valve.
  • Dial in the adjustment knob on the regulator until the outlet pressure
gauge reads 10 psi.
  • Slowly open the needle valve to desired setting.
  • When the cylinder pressure gauge drops below 500 psi, it is time to consider getting the cylinder refilled.

Starting the power Head and Setting the Effluent Flow

Start the feeder power head. Plug in the reactor pump to start water flow within the reactor. let the system run for about 20 minutes with full
flow out of the effluent line. This will push out any air from the system. After the time has passed, you can adjust the flow rate of the effluent to
a slow drip, about 50-60ml per minute drip rate. Each tank will vary, as all tanks are different.
Allow at least 2 hours after tweaking reactor settings, for things to stabilize.
It's best to make one setting adjustment, and then test the tank 24 hours later.
This takes more time, but less trouble overall.
