I doubt the Intex would help you. As you note, you are looking for an unicorn, and it's not one.

Like most AG pools, the Intex filter and circulation systems are too small. If you start with clean water, and NEVER let it get away from you, and Intex pool can work pretty well.

But, cleaning up a mess with an Intex pump and filter can take forever. It's not a matter of chemistry, necessarily, but effective filtration.

If you want easy:
+ drain
+ refill
+ start from scratch with your help
+ don't let it go -- ever.

We can tell you how to go on vacation with one, and we can tell you how to spend less than 10 minutes a day on one. But you can't skip 2 - 3 days routinely and get away with it. One of my moderators started off with an Intex and ran it very happily for 2 years I think. He's now got a giant AG pool with an elaborate deck and all sorts of add-ons. But he and his family enjoyed the Intex.

Best wishes,

Ben

PS. Not knocking the Intex SWCG -- I don't know how well it works. I just know that no SWCG is a magic pool wand.
