empowered us with this mighty blow against
the Patriarchy:

I suppose as an experiment I could turn off the Eclipse filtration for
a few hours and see what happens, since it's causing a fair amount of
turbulence, but even if it demonstrates that the turbulence is the
problem, I'm not sure what I might do with that information - I'm not
about to stop filtration on the tank, after all!

An Eclipse 2 generates quite a bit of flow ... I had an Eclipse 1 on a 20
gallon (extra high) and I can't imagine being able to successfully get an
adequate amount of CO2 into the water. Way too much surface turbulence.
But there may be a way to decrease the flowrate ... seems to me I've read
posts in which people have described doing this.
