Aquatic Experts 1.5-Inch Large Bio Balls for Ponds – Treats Up to 1,000 Gallons (300 Count) + Mesh Bag

Product overview

Aquatic Experts 1.5-inch Large Bio Balls are purpose-built for ponds, waterfalls, and high-flow outdoor filtration. Each oversized sphere provides nearly 2 square feet of surface area, creating ample space for beneficial bacteria to flourish as water moves through your filter system.

Designed for rugged outdoor use, these bio balls are made from 100% polypropylene, a durable material that resists degradation across pond environments. They are well suited for koi ponds, freshwater ponds, aquaponics setups, and large aquarium sumps. Use them loose for flexible filtration or place them inside the included mesh bag for tidy, easy placement.

Key benefits

• Large 1.5" spheres offer substantial surface area to support beneficial bacteria and clearer water.
• A 300-count pack treats up to 1,000 gallons of pond water; plan roughly 30 bio balls per 100 gallons.
• Open spine design promotes high flow and reduces the likelihood of debris clogging, keeping filtration efficient with less maintenance.
• Durable, long-lasting polypropylene construction resists breakdown and suits koi ponds, freshwater ponds, aquaponics, and large sumps.
• Solid, sponge-free core helps keep water moving and avoids centers that can trap debris, supporting cleaner filtration.

What’s included and how to use

• 300 bio balls
• 14" x 20" mesh bag for easy placement in filters or waterfalls

Usage tips: place the bio balls in your filter media chamber or inside the mesh bag near return outlets. They are designed for high flow outdoor features and work well in koi ponds, freshwater ponds, and aquaponics systems. Proudly made in the USA, they offer durable filtration media you can trust over time.

Care and longevity

Thanks to a sponge-free core and a robust polypropylene build, these bio balls maintain flow with less frequent cleaning compared to some media options. Inspect periodically and rinse only if you notice reduced flow or visible buildup.
