About This
- Large 1.5" Bio Balls for Ponds & Waterfalls: Oversized 1.5" balls designed for pond filters, waterfalls, and high flow outdoor systems. Each ball provides nearly 2 sq. ft. of surface area for beneficial bacteria to break down waste.
- Treats Up to 3,000 Gallons: A 900 count pack treats up to 3,000 gallons of pond water. Use 30 bio balls per 100 gallons (or 300 per 1,000 gallons) so you can buy the correct amount for your pond size.
- High Flow, Low Maintenance Design: Open spine structure lets debris pass through instead of clogging. Unlike lava rock, these bio balls maintain performance and rarely need cleaning.
- Durable, Long Lasting, and Safe: Made from 100% polypropylene that won’t degrade. Ideal for koi ponds, freshwater ponds, aquaponics, and large aquarium sumps. Packaged loose in a sturdy box and includes three 14" x 20" mesh bags for easy handling and placement.
- Sponge Free Core for Cleaner Water: No sponge center to trap gunk. Solid core design keeps water flowing freely for cleaner, healthier ponds. Proudly Made in the USA.
