After reading and following your posts on the drop checker did you test all of the levels simultaneously in seperate tanks or were adjustments made to the same tank over time? How did you compare colors or was it a judgement call, or did you take pictures?
I am very interested in tracking/mointoring CO2 content but I have doubts about most of the methods out there. Can one just decide if there is enough CO2 in the tank by the appearance of it's inhabitants(fish /plants/algae)?

The drop checker I purchased is similar to this one on ebay:
eBay: Co2 Drop Checker-monitoring proper dosage of CO2 (item 250082840577 end time Feb-16-07 08:24:41 PST) There is another style also sold on ebay:
eBay: NEW!! Co2 Drop Checker-Highest quality handmade glass (item 250082505885 end time Feb-15-07 08:21:05 PST) And the Red Sea unit is some times sold on ebay, but doesn't seem to be offered now.
I started looking at using the drop checker about 6 months ago, as I recall without checking back. During that time I have done many different tests ranging from in-tank comparisons to counter top testing in a measuring cup while blowing into the water to get CO2 in it. I've tested many DIY versions of the device. And, it is obvious that this is such a simple device that any version will work, and most work very well, whether DIY or purchased. I took a lot of photos during that period. One place I posted a lot is on APC, at:

You can do all fertilizing or CO2 injecting by just watching the plants and fish, but that takes experience in order to understand what you are seeing. Most of us don't have that experience.
