For lack of more information we have decided to use the Pentair 60 sq ft DE filter instead of the original proposed 48 sq ft filter in our 20,000 gallon salt water pool.
My thinking is bigger is better? The 60 sq ft is listed as 57,600 gallon in 8 hr. Maybe I can get by with running it several times per day for less time. I will be using the Pentair 3hp variable speed pump. Does anyone see a reason not to use the Pentair 60 sq ft DE filter? Is 5 hour filter run time out of the question? (Also installing Pentair IC60 SWCG)
