The mild ripple at the surface is just right. Any less and you start getting scum at the surface, and poorer oxygen below.
Yes, it blows off some CO2, but not very much, and is a good compromise between too much and too little.
I also use that filter and similar sized filters for tanks that are about 45-60 gallons. It is not enough for larger tanks. I would use 2 on my 72 gallon and larger tanks.
