I consider some kind of surface skimming device required equipment when injecting co2. I also aerate at night for a few hours. It makes a BIG difference. You can also inject co2 all you want without worry. I have some slight surface rippling with my Hydor too. This makes it somewhat harder to keep co2 in solution, but it's more than worth it.
