You can always buy it directly from Taylortechnologies.com, but at MSRP.

Not sure how you attach the sand filter to the Intex pump. Their web site isn't showing the sand filter.

Here's the big question: Do you have a level surface? If you don't you'll spend more time and effort on that than you will on the setting the pool up. It's the one thing Intex doesn't tell you. But don't blame them: Nobody else does.

I was probably the first person on PoolForum with an Intex Donut, 15x3, and we used it from 2000 to 2002. It was GREAT! and I learned so much that when I put in a nearly 20,000 gallon FantaSea, I knew pretty much exactly what to do.

Good luck!
