How to set up your CO2 Controller and why they are so good! - Equipment

Enclosed is my recently published paper on CO2 controllers. Unfortunately it requires 3 separate Word documents and is rather technical; however, I did want you to understand how valuable these devices are.

If you only want to know how to set up your controller just open part 3 and go to the section titled: How to set up your controller?

These documents are copyright and unauthorized distribution of them is prohibited; however, you may quote any part as long as point to this site and give credit to ray-the-pilot.

I suggest sending any controversial comment to me as a PM.

That is a very nice post.

PH Monitor right?

A PH controller monitors PH and turns on / off the co2 based on your set points and is how you usually control the co2 automatically.
Just wondering if your paper is on how to set up a pH monitor / controller (like the Milwaukee SMS 122) to control the co2 because I have never heard of a co2 controller.
I guess if I were to read your paper, I would get my answer.

A pH monitor just gives a single point reading of pH.

pH controllers adjust CO2 to keep the pH at a certain point.

Yep, I realize my mistake of saying monitor when I meant controller.

After reading some of the papers, is this thing actually a Co2 controller measuring Co2 and not PH.
He was adding PPM's of Co2 levels to the water but still seems to be measuring PH, not Co2.

But this might be a more accurate way to calibrate the PH probes instead of using PH solutions.
IDK, is it? good idea though.

I got out of it that he was using a pH monitor and measuing pH after he had added so much CO2 to the tank. But who knows? Its published though... I don't know where....Aquatic Plant Central?

No its not! Try explaining this one to the scientific community....LOL. pH solutions are known standards. No one could mix up a little CO2 into water and come nearly as accurate as pH calibration standards. Remember CO2 is a gas and when dissolved in water it will very quickly gas off.

OK, I buy that, sounded technical in his paper though.

I guess I meant that since he knows the co2 levels exactly (I guess he wouldn't, but the way he set up his control sounded sound) then you can set your probes to that known level and you would be measuring the co2 more then the PH it is calculated out at.
IDK it sounds interesting, but I am really tired at this point, so IDK much anymore. LOL
