Bio Comb Fluidized Media
Biological filtration that is excellent for gravity filters, pressurized pond filters, aquafarming, and hydroponics. Fluidized media provides protected surface area for beneficial bacteria to colonize and grow. Low-maintenance and self-cleaning, biological filtration improves water oxygen levels and overall water quality.
Back in the day, lava rock was an effective media to cultivate beneficial bacteria in koi ponds and water gardens. Problem is, lava rock 'slimes over' in a matter of weeks and loses its effectiveness. Bio Balls, with their unique geometric design, have a very large surface area to dramatically increase beneficial bacteria growth. Lightweight, durable, and easy-to-use, bio balls allow you to come safely maintain higher fish load with the same pump and filter.
