Hi Folks,
It would appear that JBL have decided on a new optimum CO2 level in users' tanks. Instead of the 30 mg/l figure, which has been 'the norm' for a good many years, JBL seem to be rolling out their latest drop checker (DC) test sets with a new optimum of 20 mg/l. See below:

Note also that the figure below the optimum is 12 mg/l and the figure above is 50 mg/l. I haven't yet fathomed out what combination of KH and reagent (e.g. bromothymol blue) JBL are using.
