Re: Large tank filtration

I have a wet/dry filter on my 200 gallon planted tank.  CO2 consumption is
a little high, a 20 pound tank lasts roughly 3 months which works out to $4
per month.  This seems like a reasonable cost to me in view of the size of
the tank.

This is a reef ready tank with two internal overflow boxes and it appears
that most of the CO2 is lost in the turbulence of the overflow boxes rather
than the wet/dry filter.  I measured the pH in the overflow boxes and the
sump to see how much CO2 was driven off in each but I can't remember the
exact numbers.  If anyone is interested I'll repeat the measurement.
