You cannot see the water moving from the circ pump. If you're in the tub and the heat is on you can feel the current from the gray vents in the footwell but that's about as strong as it needs to be.
I've had zero problems with filters running 4 hours per day. If your water isn't staying clear I'd bet it's a chemistry issue, not a filtering issue. Your circ program at 5 hours should be more than enough.
FWIW I have an A8 and I struggled with keeping the water crystal clear without mid-week maintenance until I switched to bromine with a floater. Now I can maintain the water on weekends, zero mid-week checks, without a single issue. I've been on bromine for about 9 months now and will never go back.
