This is my second year with my pool, and last year after the pool was finished I had full flow on the waterfall and never needed the pump at %100. I think I had the pump at %70/%80 when the waterfall was on. This year since opening the pool I have struggle to get the same flow. Below is what the waterfall looks like running at %100. I was wondering if the valve in the picture below can be adjusted to send more flow to the waterfall and less to the return? Maybe the PB had this adjusted last year and that's the reason for the different flow? I have cleaned my filter with water only. Picture below of what my filters look like. I have also cleaned the waterfall with a credit card, but nothing has changed the flow.
