The AquaPro 19" would be a great choice for use with a 21' Round Above Ground Swimming Pool. This AquaPro Sand Filter System includes a powerful 2-HP pump with energy-saving 2-speed functionality and the longest warranty - 2 years, as opposed to most other sand filters with 1-year warranties.
Expand the "Filter Systems" section on the pool customization page and select the AquaPro 19" Sand Filter System 2-HP 2-Speed Pump. All of the accessories, including the filter system, on the pool customization page are discounted. These discounted prices are only available when the accessories are purchased together with a swimming pool. If you choose to purchase any of these accessories separately (at a later date) they will not be discounted. Take advantage of these extra savings now!
We also have a great alternative to using pool filter sand. The Platinum Filtra Balls For Sand Filters are a lightweight filter media that replaces the sand inside of your sand filter system. These Filtra Balls offer better filtration than filter sand and are significantly lighter than filter sand (1 box of Filtra Balls weighs less than 2 lbs and is equivalent to 50 pounds of normal filter sand). The AquaPro 19" Sand Filter System with 2-HP Pump requires 3 boxes of Filtra Balls. Simply expand the "Accessories" section on the pool customization page to select the Filtra Balls - 3 Pack.
