Dupla tests

Gee, George, I like the Dupla CO2 a lot.  It SEEMS highly accurate, being a
titration method.  And the numbers I get seem reasonable.

On another subject, has anyone noticed the # numbers of the recent aquatic
plants distributions?   They seem to have started back at one.  Is that on
purpose or is it a bug?    Dave
