Based on my experience, that's not true. If your set-up
shedding CO2 at a realtively high rate before installing a
sump system, then the sump system won't make a really big
diff. IF the set-up was very CO2 efficient to start wtih,
then switching to a sump can as much as double CO2 use. I
can't think of where all the extra is all going except up
up and awayyyyyy.

Been there, read that. Imagine my surprise when I installed
the sump ;-)
