EasyPro PBF10000 Bead Filter – Pressurized Koi Pond Filter for Ponds up to 10,000 Gallons

The EasyPro PBF10000 Pressurized Bead Filter provides high-performance mechanical and biological filtration for ponds up to 10,000 gallons (or up to 5,000–6,000 gallons with heavy koi loads). It processes up to 5,400 GPH through 4.5 cubic feet of Ultimate Tube Media — EasyPro's proprietary high-surface-area biological filtration material that supports dense beneficial bacteria colonies while minimizing back pressure on your pump. The filter ships fully assembled with a 6-position control head, pressure gauge, 2" unions, and clear waste line for visual backwash monitoring. Backed by a 3-year limited warranty. 5,400 GPH Max Flow 10,000 Gallon Capacity 4.5 cu. ft.

Why Ultimate Tube Media Outperforms Conventional Bead Media EasyPro's Ultimate Tube Media is the biological filtration core of the PBF series — and it's meaningfully different from the spherical bead media used in older pressurized filter designs: Higher surface area per cubic foot. The tube geometry of Ultimate Tube Media creates more colonizable surface per unit volume than round beads of the same size — more surface means more beneficial bacteria, which means faster and more complete ammonia and nitrite conversion for any given pond load. Minimal back pressure. Round beads pack tightly when pressurized, creating significant flow resistance that forces pumps to work harder. Ultimate Tube Media's open cylindrical geometry allows water to flow through the media bed with dramatically less resistance — your pump maintains near-rated flow rate through the entire filter, not just at low-pressure. More effective backwash. When you reverse flow through the control head, Ultimate Tube Media separates and tumbles more readily than tightly packed beads. Solids release from the media surface faster and exit through the clear waste line in fewer backwash cycles, conserving water and reducing maintenance time. Adding the optional blower (included in the PBF10000BL) further improves this by agitating the media before water flow begins. Fish-safe formulation. Ultimate Tube Media is inert, non-leaching, and approved for use in ponds with fish at any stocking density. It does not introduce any plasticizers or chemicals into the water column. Sizing the PBF10000 for Your Koi Load The 10,000-gallon rating applies to ponds with a moderate decorative fish load — typically one koi per 250 gallons or less. For dedicated koi ponds or mixed koi-pond systems with heavy stocking, apply a conservative 50% reduction to the rated capacity. Key guidelines: Light fish load (decorative pond, occasional koi): PBF10000 appropriate for ponds up to 10,000 gallons at stock rates below 1 inch of fish per 20 gallons. Moderate koi load (show-quality koi, 1 fish per 250–500 gal): Size the PBF10000 for ponds up to 6,000–7,000 gallons for reliable water quality and ammonia control. Heavy koi load (densely stocked koi pond, premium stock): PBF10000 is appropriate for ponds of 4,000–5,000 gallons. Consider adding a UV clarifier and ensuring pump delivers the full 5,400 GPH rated flow through the filter. Never oversize your pump beyond 5,400 GPH. Higher flow rates force water through the media too fast for effective biological contact — bacteria colonies are disrupted and mechanical filtration is incomplete. Use a bypass valve if your pump exceeds rated filter flow. Frequently Asked Questions How does the EasyPro PBF10000 provide biological and mechanical filtration? The PBF10000 combines both filtration modes in a single pressurized housing. Mechanically, water is forced through the 4.5 cu. ft. Ultimate Tube Media bed under pressure — suspended solids are physically trapped in the media matrix and accumulate until removed by backwashing. Biologically, the high surface area of the Ultimate Tube Media tubes provides an ideal habitat for beneficial nitrifying bacteria. These bacteria convert fish-toxic ammonia to nitrite, then nitrite to relatively harmless nitrate, completing the nitrogen cycle. The pressurized environment keeps the media moist and oxygenated even during low-demand periods, maintaining the bacterial colony in good condition year-round. What is the maximum recommended flow rate for the PBF10000? The PBF10000 has a maximum recommended flow rate of 5,400 GPH (90 GPM). Higher flow rates are technically possible but reduce filter effectiveness because water passes through the media too quickly for complete biological contact and mechanical trapping. Size your pump to deliver approximately 5,000–5,400 GPH through the filter. If your pump is larger, install a valved bypass line that allows excess flow to return to the pond without passing through the filter, so you can tune the filter flow rate independently of your pump's full output. How often should I backwash the PBF10000? Backwash frequency depends on fish load, feeding rate, and seasonal debris. For most 10,000-gallon ponds with moderate koi, backwashing once every 7–14 days during peak season (late spring through early fall) is a reasonable starting point. The included pressure gauge is your best indicator: when filter inlet pressure rises 5–8 PSI above its clean baseline, it's time to backwash. The clear section of the waste line shows you when backwash is complete — continue until the water runs clear, then rotate the 6-position control head back to "Filter." Using a blower (included in PBF10000BL, optional here) before the water backwash significantly improves media cleaning and reduces water loss. Does the PBF10000 include a pump or UV clarifier? No — both the pump and UV clarifier are sold separately. A pump is required to operate the PBF10000; an external self-priming pump rated for 2" connections is recommended. For koi ponds, a UV clarifier is strongly recommended alongside this filter — UV eliminates free-floating algae and pathogens that the bead filter's mechanical stage alone cannot address. The EasyPro PCU110W 110-Watt UV Clarifier with 2" unions is a common pairing at this scale. Call us to confirm a compatible pump and UV configuration for your specific pond: (765) 508-4352. What is the difference between the PBF10000 and the PBF10000BL? The PBF10000 is the filter without a back-flush blower. The PBF10000BL is the identical filter with an integrated back-flush blower included. The blower agitates the Ultimate Tube Media prior to backwashing — breaking up media clumps, dislodging fine debris from the tube surfaces, and preparing the bed for more effective water backwash. Benefits of the blower include: faster backwash completion, less water loss per cycle, and a cleaner media pack after each maintenance session. For heavily stocked koi ponds where backwash quality directly affects water clarity, the BL variant is the recommended choice. Both models carry the same 3-year limited warranty. What are the physical dimensions of the PBF10000? The PBF10000 measures 31 inches in diameter by 51 inches tall. Note that the 31" diameter is the tank only — the 6-position control head adds additional width on one side. Height is measured from the floor to the top of the handle. Plan your equipment pad or vault to accommodate 33–34" diameter clearance with control valve access, and 52–54" vertical clearance for removal of the control head during maintenance.
