So I am still torn between an 18 foot and 21 foot pool (54") and am waiting on my HOA to see if they will allow the 21 foot. My question is would the Pentair 342001 VS Pump and the Pentair 160354 Clean & Clear RP Cartridge Filter be a good setup for either size pool? I plan on running 120 volt to the pump and use 1.5 plumbing. I know this might be a little overkill but like the saying goes "Go big or Go Home" Lol
