You are correct...you should cut the power when removing the filters and the circ pump does pull through the micro clean filter. I do not reset every time I cut the power. No need to. Just leave it to reset at program start time.
I do not rinse my filters weekly unless they are very dirty. Generally, I just clean with filter cleaner once per month. IMO, pulling filters is a chore and the Optima is simple to do compared to others.
