About This Product

Upgrade your above-ground pool filtration system with FlowXtreme Cotton Tails Filter Media. Tightly woven from polyethylene strands, this innovative sand-alternative filters water down to three microns for crystal clear pool water. The filtration rate is ten times greater than sand and traps small particulates that are not easily removed by sedimentation. With greater filtration capacity, the FlowXtreme CottonTails won’t clog your filter and require less backwashing. Plus, one 1.5-lb box or bag equals 50-lbs of sand. Eliminate the hassle of heavy, hard-to-manage bags of sand and enjoy a lighter, more efficient replacement. 90-day warranty.


  • FILTERS TO 3 MICRONS - Tightly woven polyethylene strands filter out even the smallest particulates. Cotton Tails provide excellent water clarity, purity, and quality for a more enjoyable experience in your swimming pool.
  • SAVES TIME & MONEY - Unlike sand, Cotton Tails Filter Media won’t clog your filter and will require less backwashing for maintenance purposes. You'll only need to backwash when your tank's PSI reaches 25, saving you time and money.
  • A LIGHTWEIGHT ALTERNATIVE - A 1.5-lbs bag or box is equivalent to 50-lbs of heavy, hard-to-manage sand. Stop struggling with large, heavy bags of sand and switch to a lighter, simpler filtering solution.
  • WASHABLE AND REUSABLE - Easy to maintain and clean, Cotton Tails will last for several pool seasons. Simply place the filter balls in your washing machine whenever it’s needed, or at the end of each season, and enjoy years of hassle-free filtration.
  • 90-DAY WARRANTY - The manufacturer warrants this filter media to be free from defects in workmanship and materials, under normal residential use and conditions, for a period of 90 days.

Very good substitution of sand. I chose to go this direction to avoid sand from getting into the pool as this sometimes has happened in the past. So far it is working great and keeping my pool clean and clear.

So much easier and convenient than sand. Read directions because you can't use liquid clarify with this product! Great product and I love the results!

Jury is still out
Still in the process of opening the pool/getting it ready for swimming so I can't definitively rate the materials filtering qualities, but the cotton "balls" ejecting out during backwashing the filter is odd to say the least.
