I am putting in an L-shaped pool. 16x32 with 8x12 L section. 3-1/2' shallow end 6' deep end. Can anyone recommend a great pool pump that will turn the water quickly and efficient (2speed?). Also, any suggestions on sand filter vs cartridge? Any suggestions appreciated.
Thanks.

Do you already know the total volume? If not post more details of where the shallow is and where the deep end is in the L shape.

What size plumbing are you planning?

Any water features, solar panels, etc.?

Those are conflicting requirements. The faster the pump turns over the pool, the less efficient it will be. Slower flow rate equals better efficiency and better filtering.

Any specific reason for requiring a fast turnover?

Pool size is 16x21 deep end (down to 7' deep)...11x24 shallow end (3-1/2' deep). Just looking for the best bang for buck...efficient, etc. Tigerflex underground...2" PVC above ground plumbing.

If you don't plan on having any water features or a spa, then the Whisperflo WFDS-3 or 24 would be a cost effective pump. Since you close for the winter, a VS may or may not pay for itself but it depends on what you pay for electricity and how long the pump will last. But since you are building a new pool, the cost difference is not really that much compared to the cost of everything else so I will usually recommend a VS for new builds. The Intelliflo 011018 is a pretty good deal right now and would give you a lot of flexibility down the road should you add solar or other features.

As for filters, again since you close for the winter, a sand filter may be easier to deal with when opening. A cartridge can also work but you need to build in a filter bypass so you can recirculate while killing the algae. Otherwise the cartridges can clog up very quickly and you get into a never ending cleaning cycle. However, the cartridge filter will be a little more energy efficient than the sand. It kind of depends on what is more important to you.
