We are putting in a 700 sq ft inground concrete pool and would appreciate your expertise on a few questions:
1) Our pool building is offering us a Jandy 1.5 hp filter. We can choose between "mineral" or "salt"; this is a cartridge system. The pool salesman says he uses the mineral cartridge in his own personal pool and they love it, but that this system is "easily convertible" to salt if we change our minds. So I'm confused! Is a mineral cartridge filter a good thing, or not? I believe it would be an upcharge to get the salt system.
2) Do we want a dual speed pump, or a variable speed pump? I've tried to google for the answer and yikes, I can't figure it out!
Thanks so much!
