That certainly looks effective if not beautiful. And, if you only want to verify that your bubble rate is giving you the amount of CO2 you desire, this should work perfectly. Hey, maybe we could get Home Depot to buy a few of the ADA ones for their tool rental department?

For those who don't read many other aquatic plant forums, Tom Barr did some experimenting with this device and came up with the idea that you could get rid of the air gap entirely, and speed up the response rate considerably, just by using a gas permeable membrane to hold the reference KH solution. Then, if that membrane is in the form of a stocking over the business end of a pH probe, you have a CO2 probe - with fast reaction and great accuracy. He has done a prototype, of sorts, and it works. And, he is working towards getting this available for all of us.
