CO2 regulator

[pappasmurf]

Having a problem regulating my calc reactor.
Using a milwaukee Ph meter and milwaukee co2 regulator.
PH meter has been adjusted to 4 and 7, but jumps all over the place, which sets off the co2 regulators solenoid constently.
I was wondering which CO2 regulator most of you use, and if anyone has had a problem like this, and if so, whats the cure? Tim

Tim:

How old is the Ph probe. They say to replace them about every 8-12 months. I don't replace them that ofter either but maybe you should try a new one.

Tim Try to calibrate using 7 and 10 solutions if your meter allows it. Since our Ph is closer to that range it will/should give more accurate readings. i also let my readings settle for a while during calibration before going to the next solution. then going back and forth between the solutions to tweak the fine tuning. When I am done I will try reading my test solutions to make sure the calibration is correct. Also be sure to rinse the probe with RO water before switching between cal solutions. If it won't stay stable sounds like a bad probe. Sounds simplistic but I hope it helps. JJ

Probe is less than 2 months old. I recalibrated it with 4 and 7 solution 2 days ago and it calibrated fine. I'll try 4 and 10 solution and let you know how it turns out.
Which co2 regulator do you guys use?



Thanks for all your help, Tim

I have and like the reef fanatic regulator. It has a preset low pressure output. It helps prevent accidental reactor explosions.

Tim it may calibrate ok but possibly not holding the calibration. I've had that happen to me before. Easy way to check is to put it into a known solution and see if it reads properly. What brand is the probe? I tried an el cheapo ebay probe before and found out the savings on the probe are not really savings in the long run.

I had issues for the past year dialing in my Milwaukee regulator. I would adjust it and it run perfect, next thing you know, its dumping. One or the other. Just changed out the needle valve for a new RF needle valve and 10 minutes later, I have not touched it since.

Best $20 I have spent in a long time.

I believe it's a pin point probe. Calibrated it with 4 and 10 solutions, it checked out ok.
Not sure if the problem is the probe, the regulator or the ph meter, so I quess I'll have to breakdown and replace all 3 before I blowup another calk reactor.
Thanks for all the help, Tim

Had the same issues with two controllers, but it was the regulator for sure.

Start with the cheapest fix and go from there.

By chance do you know if you'd ever had water back up into the regulator? That would mess up the needle valve if not the regulator as well.

Thanks guys. Phishy has a regulator and probe, so I'll make the trip. Thanks Tim

Make sure the new regulator has a needle wheel adjustment or add one like jh2pizza said or you could be bacj in the same boat. I have mine set up at about 2 drops of effluent for every CO2 bubble.
