Just a quick update... That deal turned out to be to good to be true... I get an email from Amazon stating 4-6 weeks delay in delivery due to backorder. I canceled the B/O and went with the 2650 which I figured could be used for when I get a bigger pool. Perhaps way, way overkill for what I need (which could be good, I can run the filter less hours?). Total cost was ~197 with free shipping. Now with this size filter / pump setup how many hours a day should I run it?
