Attach the regulator to the cylinder valve placing the O-ring between the regulator and the tank and tighten with a wrench. If you leave the O-ring out, you will lose gas.
Unscrew the large brass ring from the bubble counter and fill the bubble counter 1/2 full of fresh water. Be sure the needle valve is closed before filling with water. Once filled replace the brass ring.

Before opening the cylinder valve turn the regulator adjustment knob (BLACK) counter clockwise until tension is no longer felt on the knob. Do NOT fully remove the regulator flow adjustment knob. IF THE CYLINDER VALVE IS OPENED WITH THE REGULATOR KNOB TURNED IN, DAMAGE TO THE REGULATOR DIAFRAM OR RIGHT GAUGE CAN RESULT

VERY SLOWLY and CAREFULLY open the cylinder valve COMPLETELY to seal the cylinder valve packing. The amount of gas can now be read on the high pressure gauge (LEFT GAUGE).

Plug the solenoid (electric plug) into a grounded plug. Open the needle valve all the way (knob on side of bubble counter) by turning it counter clockwise.

Turn the adjustment knob (black knob) until you get a reading on the low pressure gauge (RIGHT GAUGE) of approx 10 lbs or less on the inside set of numbers (psi). You should now see bubbles in the bubble counter. It is recommended that you use the bubble counter rather than the right gauge to determine flow rate. ONLY USE THE NEEDLE VALVE IS YOU CAN NOT GET EXACT FLOW FROM ADJUSTMENT VALVE

Unlug the solenoid (electric plug) from the wall or wherever and unscrew the compression fitting and pa the air hose through the fitting and attach air tubing to the n ipple (copper n ipple above the bubble counter). Be sure your air tube fits tightly on the n ipple and is pressed all the way down. Slide the compression fitting onto the n ipple and tighten.

Plug the solenoid back in and adjust the bubble counter on your regulator using the adjustment knob (black knob) as described above. Use the needle valve (side of bubble counter) for fine tuning the bubble count if you cant get it by using the black knob.

You want to have 30 bubbles ever minute entering the bubble counter. The outflow (into tank) should not be a stream but more like a trickle. (use a valve and adjust it so that the water out is just becoming a stream but is still broken and not continous. It will take about 12 hours to see a result but your ph coming out should be 6.5 (REMEMBER TO PUT THE SOLENOID ON A TIMER SO THAT IT IS NOT CONTINOUSLY POURING LOWER PH WATER AFTER THE LIGHTS GO OUT. HAVE IT COME ON WHEN YOUR LIGHTS ARE ON AND OFF WHEN THEY GO OUT) Also, remember that when your calcium level drops due to the amount of corals you have consuming it, simply adjust your amount of CO2 being adding to the chamber so that more aragonite is dissolved thus boosting your calcium level. This requires adjustment and is different for each aquarium.
