I think your sump may be the problem.
See you are loosing a ton of co2 with the water Cascading over the
bioballs. I would suggest trying it wiht no sump and a different
filter or rigging your filter so it does not cascade and release the
co2 you are adding

that's what I thought at first too. But it turns out that it's not nearly
as bad as you would think with a trickle filter. here is an article on the
subject http://users.frii.com/gbooth/Aquatic...index.htm#loss
