[APD] CO2 bubble rates in sump vs non sump tanks?

[Dgrim62 at cs_com]

Hi everyone, 

If anyone on the list has gone from a C02 injected non sump filter setup to a 
sump type setup on the same tank, how did the switch affect the amount of CO2 
you injected?

I just set up a 240 gallon with a sump and I am using more CO2 than I did 
with a cannister type setup (on a 125 gallon). I have minimized turbulence 
wherever possible to reduce off gassing as much as I can. The tank also has metal 
halide lighting instead of the power compact I was using before.

Thanks!

Regards,
Dave
