I have a Milwaukee MA957 co2 regulator/bubble counter. No instructions on what to set regulator at or how many bubbles per x amount of time equals what?? Is there a chart? I have a 20# co2 tank. Help please!

Operating Instructions for the Milwaukee MA957
BEFORE YOU START! :
Secure cylinders so that they will not tip or fall.
Inspect the cylinder valves for damaged threads, dirt, oil, or grease. Remove dust and dirt with a clean cloth.
Crack open the cylinder valve for an instant to blow out any foreign matter in the throat of the cylinder.
ATTACHING THE REGULATOR:
Attach the regulator to the cylinder valve placing the supplied plastic o-ring (not shown) between the regulator and the tank. Tighten with a wrench. Omission of this o-ring will cause loss of gas!
Unscrew the large brass ring (G) from the Bubble Counter (H) and fill the bubble counter 1/2 full of fresh water. Be sure the needle valve (B) is closed before filling with water. Once filled, replace the brass o-ring (G).
Before opening the cylinder valve turn the regulator adjustment knob (E) 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 CLOSED, DAMAGE TO THE REGULATOR CAN RESULT!
VERY SLOWLY and CAREFULLY openthe cylinder valve COMPLETELY to seal the cylinder valve packing. The amount of gas in the cylinder can now be read on the High Pressure Gauge (D).
Plug the solenoid (C) into a suitable, grounded, AC Wall outlet, Hanna pH Mini Controller, or Milwaukee SMS122 pH Controller. The solenoid uses slightly more then 6 watts and it is normal for it to feel warm during operation.
Open the needle valve (B) by turning counter-clockwise.
Turn the adjustment knob (E) clockwise until you get a reading on the Low Pressure Gauge (F) of approximately 10lbs on the outside set of numbers (use the numbers on the top row). You should now see bubbles in the counter.
Unplug the Solenoid (C) from the wall or controller and unscrew the compression fitting and pass the air hose through the fitting and attach the tubing to the nipple (A). Be sure your tubing fits tightly on the nipple and that it is pressed all the way down. Slide the compression fitting onto the nipple and tighten.
Plug the Solenoid (C) back into the wall outlet or pH Controller unit and adjust the bubble count on your reactor using the needle valve (B). Fine tuning the count can be accomplished with either the needle valve (B) and by adjusting the regulator output pressure with adjustment knob (E) as discussed in the pevious step. The more you increase the pressure as indicated on the low pressure gauge (F) the more difficult it will be to fine tune your bubble count using needle valve (B). Therefore it is more desirable to keep the pressure indicated on the low pressure gauge (F) low and adjust your bubble count using the Needle Valve (B).

Trouble Shooting MA957 Regulator
The procedure is as follows:
If you have a pH controller, unplug the solenoid from the controller and Plug your solenoid into a wall socket or power strip. Do not have it plugged into any type of controller or timer to do this adjustment.
Turn your CO2 bottle off. Go to the regulator and turn the main knob counterclockwise till you feel no pressure. Next go to the needle valve that is underneath the bubble counter and turn it counterclockwise all the way out.
Now go back to your CO2 tank and turn the tank to full open. At this point, even with the tank full open you should have no bubbles coming through the bubble counter.
Very slowly, turn the big knob on your regulator in until you start seeing some bubbles come out of your regulator bubble counter. Do not pay any attention to the right side gauge. All we are interested in is the bubble counter.
You must proceed very slowly when trying to adjust the CO2 regulator. Go slow, slow, slow; take your time, we want to slowly work the bubble count up.
Turn the knob one eight to one quarter turn and wait about 30 to 45 seconds or longer before making any further adjustments. Continue with this process until you get a bubble count that is equal to or a little greater than what you're looking for. At a bubble count of 60 bubbles per minute, you might want to take it up to 80 bubbles per minute and then use the needle valve to crank it back down
The right side gauge is not relevant to adjusting your gas flow. Indeed, we have been trying for several months to get them to take the right side gauge off of the regulator because the bubble counter is your true an accurate gauge. Therefore, any reference to the right side gauge serves no purpose.
This procedure, when followed, works about 90% of the time in getting regulators consistent in their flow. The primary problem for poor flow consistency is that too much gas is backed up behind the needle valve causing the diaphragm in the regulator not to function properly.
If you're using a pH controller plug your solenoid back into the pH controller box at this time.

Thank you for that information, mine actually came with instructions...
I was looking more for a way to convert bubbles per minute to something usable for this application. Another user posted about using it to fill a gallon bag and doing the proper calculations
from there so I think that's what I'm going to do.

*yea.. i suck at math.. so im guessing you should be using "volume" as measurement for your bubble thing.. not sure.. im high.. enjoy your weekendThank you for that information, mine actually came with instructions...
