Is it necessary to have the return valves churn the surface, or can effective circulation be achieved with having the water directed more below the surface.
I ask for two reasons.
1. Aesthetics.
2. Acid use, I have a waterfall, occasional use, and a spa spillover, so I am introducing air nearly everywhere and adding about a pint of acid a day, new pool too so I know new plaster uses more acid. Just thinking I don't need this extra water churn if not critical for circulation.
