EXCLUSIVELY MADE FOR KOI PONDS - Our 1 inch thick Classic White Fine Koi Pond Filter Media provide excellent mechanical pond filtration for clean water while providing important oxygenation for your ornamental garden pond. Designed for ponds, but great for aquariums, too!

CRYSTAL CLEAR POND WATER - Place your koi pond filter pad in flowing water such as water being pumped through your pond skimmer box to trap to remove uneaten food, waste, decaying plants, detritus, and other large and fine floating particulates from the water. Changing filter pads regularly will increase water quality by removing solid organic compounds before they continue to break down and add additional nutrients to the water in your pond.

CUT TO FIT - Made in the USA! Our bulk Classic White Pond Filter Pads can easily be cut to any size needed and will save you even more money over purchasing ready-made, pre-cut filter media. This Pond Filtration Media is CONSTRUCTED OF DURABLE POLYESTER FIBERS bonded by our special resin to give it exceptional strength.

OUTSTANDING FILTRATION: Our biofilter balls are covered in spines to dramatically increase the surface area of each ball to nearly 2 square feet providing space for a massive number of beneficial bacteria to colonize. These good bacteria break down harmful organic waste. You will receive approximately 300 LARGE 1.5" bioballs in a 14"x20" mesh zippered bag.

TOUGH AND UNIQUE: Our large bio balls spherical shape and precise spine placement permits them to pack tightly into any shape or filter type without losing surface area. Molded from high density plastic, these bio media balls are lightweight but tough enough to keep their shape and will never degrade or wear out. This makes these heavy-duty bio balls perfect for pond filters for outdoor ponds or as a bio media for aquarium filter.

TRUSTED: Our bio filter balls are 100% polypropylene making them a safe reliable biological media for use as koi pond bio filter media, freshwater aquariums, and for saltwater fish tank bio media, aquaponics bio ball media, and much more. These biomedia balls can be used loose or in the mesh bag with plastic zipper.
