Sorry to be such a pest but I want to do things right as I am replacing the filter and pump. I've posted a few questions concerning filter size but the response I got was based on the pump which I've decided to also replace so I want to make sure the pump is the right size. Originally, the pump was a 2hp. I replaced the motor 2 yrs ago with a 1.5 hp but I'm wondering if that is still too big. What is the best sized pump for these measurements?
Size: IG pool with spa (about 21000 gallons), size is kind of a figure 8 shape of a rough estimate guess of 20-25' wide x 35-40' long
Input: 1 skimmer, 1 spa drain and 1 main drain, 2" plumbing
Output: 3 pool returns, 4 spa returns, 1 pressure side cleaner outlet, 1.5" plumbing
