I have toyed with the idea of putting in a smaller impeller, but there is one nice thing about having an oversized pump. I can run an auto pool vac and a solar heater at the same time with the throttle valve wide open. This combination of suction and return restriction keeps the flow down where I like it so that even though the valve is fully open, I am not blowing fine particles through my filter(ish). I am sure its not so good on the pump, nor the electric bill, but I justify it because our electricity is so cheap here, lots of hydroelectric dams.

I will check on the IP address thing. Thanks.
