My advice is to RUN and not walk away from a system 3 filter! Look into a Pentair clean and clean or clean and clean plus instead. Depending on just how 'dirty' your pool gets the single cart 150 sq ft clean and clear might be enough. If you need larger filtering capacity, the clean and clear plus are 4 filter systems. How many sq ft is your current Jacuzzi and how often do you need to clean it? I have a 150 sq ft clean and clear on a pool/spa about half your size and really only need to clean it once a year or less if I wait for a 10 PSI pressure increase BUT I do clean it 2-4 times a year because my pool is open year round!
