Pentair sand filters

I am looking at a 27-30k gal free form pool. One PB states the TR-100 is the one the other states the TR-140 is.

Pentairs literature shows TR 100 capable of 98gpm flow and 24 hr turnover is 140,000 gal. This seems more than adequate? Doesn't it?

They will both work, but you will be happier with the larger filter. Larger filters are slightly more efficient and can go longer between backwashing/cleaning.

More important than the pool size, be sure to matchthe pump size to the filter. a Full Srvice 1hp pump would be a very good match for the TR100.

What about a 2 speed pump, would you still recommend 1 hp? Of course, the PBs are recommending 2 hp...

Thought i would give additional info to help with pump sizing. Pool size is roughly 50x22. Will have three 2in suction outlets (2 skimmers, 1 drain) and 5 or 6 returns. I would like two 2 in return loops. Longest run to pad would be 80-90 feet, pool and pad at same level. Only water features would be 2 bubblers on a tanning ledge. Will have booster pump for pressure cleaner or use robot.

If you're running all the inlets and outlets separately back to the pad a 1½ hp pump would be a good fit. I'd also go with the larger filter. Given the bubblers I'd consider running two pumps. One for the main system and one for the bubblers. Either that or go with a variable speed pump. The beauty of a VS pump is that you can adjust the flow to whatever you desire it to be and get the bubblers exactly like you want them.
