I am designing a new pool. Size will be roughly 16.5-17k gallons. Two PBs have suggested different filter. One being the Pentair 320 and the other Pentair 200. I have received lots of helpful input on my New Pool Build thread suggesting to go even bigger like the 420 or 520 but thought would start a separate thread just on this topic.
Cost is not so much an issue. I just want to make sure I have a good setup that will run efficiently and smoothly for years to come. The 200 likely works but am leaning to go bigger to offer some buffer and put less strain on the filter.
Thoughts are welcome.
