Currently on my 20 Long tank, I'm using that little Hagen co2 system. The problem is, based on the pH/kh table, even with this i'm at around 2ppm of co2. As i'm still living at home, i'm forbidden to go pressurized. If i use a larger bottle, say a gallon milk jug for a co2 bottle, would that create enough co2 to help?
I also dose with flourish excel.

PS. sorry if this doesn't make sense, it's late and i'm tired ;)

Where would I be attaching the lexan to? If i keep the tank topped off to the correct point, there's actually not much surface agitation.

I had been considerding adding an Aquaclear powerhead with quickfilter attachment to the tank as well, in the back right corner. As it's a 20 long tank and the penguin is in the back left corner, there's not much water movement at the opposite side of the tank.

With the filter you're using you probably have a significant amount of surface agitation. You can use a sheet of lexan attached to the outflow on your Penguin filter to cut down on the CO2 loss. Give that a shot and let us know how your CO2 levels are.

Cheers,
Anthony
