As for diffusing the DIY CO2, you have several options. As mentioned, you can use limewood diffusers. Some people have had success with using ceramic disk diffusers, but I could never get them working with DIY CO2 (it might be because they don't generate enough pressure consistently). Alternatively, you could always just feed your CO2 tubing into the intake of your filter and let the impeller smash up the bubbles.
