Sending this again as it didn't make it to the list the first time around:

I'm just beginning to experiment with CO2 injection (via DIY yeast method), and I'm having a hard time figuring out just what the CO2 level in my water really is.

I'm testing with a Red Sea Deluxe fresh water kit.

I'm using local tap water, which is both very hard (around 17 GH and 25 KH by my test) and alkaline (pH is 8.0). When I test with the CO2 test kit I get essentially no result - this is one of the tests where you count the # of drops needed to change the color of the sample. I stopped counting at 30, but I'm pretty sure I don't have CO2 levels that are really that high (30+ ppm) - my fish seem to be doing fine.

The test kit literature implies that I should try to lower the hardness and pH for optimum plant growth, but I'd like to see how things go without messing with it too much first. I figure I'm safer working with what I have than trying to mess with mother nature. ;-)

Any other methods I can use to test? Can somebody explain why this test isn't working?
