It is true that with heavily planted tanks or sensitive plants you want to minimise the loss of CO2 but you don't want stagnant water either. I tend to stick with the hardier plants, some of which even do better in current (like long leaf pond weed or black moss). If you have enough fish producing CO2 or use a CO2 supplement it balances out.
