GCTek AquaBead Filters
The GC Tek AquaBead is a pressurized bead filter that handles mechanical and biological filtration in one tank. It uses small BioGems beads for fine mechanical filtration and a large surface area for beneficial bacteria. Omnifuser™ internals bring water in at the lowest point and out at the highest, so the whole media bed does the work and heavy solids are pulled from the bottom of the tank and flushed out on backwash.
• Five Versions: Standard, Low Head, X2, X2 Low Head and 3-Inch.
• Sizes for Ponds up to 25,000 Gallons: 1.75 to 10.0 cu ft of media.
• 2 HP Media Agitator: Blows air through the media on backwash so it never clumps.
• ALISS Life Support: Hook an air pump to the multiport valve to keep bacteria alive during a bypass or pump failure.
• Built to Last: Double-layer fiberglass tank rated to 58 psi with a Limited Lifetime Warranty.
Which AquaBead Premium Pond Bead Filter By GCTek Do I Need?
GCTek AquaBead Premium Pond Filter (Standard)
Side-mount multiport valve. The original AquaBead, in 1.75, 2.50, 4.25, 6.0 and 10.0 cu ft.
AquaBead Premium Low Head Pond Bead Filters By GCTEK
Water bypasses the multiport valve in filter mode and only runs through it to backwash. Lowest restriction, so a smaller, lower-amp pump can do the same job. 1.75 to 10.0 cu ft.
AquaBead X2 and X2 Low Head
Everything doubled inside and out so two energy-efficient pumps can run on one filter, filtering a 20,000–25,000 gal pond on about 5 amps. 6.0 cu ft (30″ tank) or 10.0 cu ft (36″ tank), with Classic (two multiport valves) and LH2 (two Low Head valves) options.
AquaBead 3-Inch
The 6.0 and 10.0 cu ft filters with 3″ unions for big flows and lower friction loss (models 6.3 and 10.3).

Before You Order a GCTek AquaBead Low Head Pond Bead Filter or Standard
- Size the filter to your pond volume and fish load, not just gallons. Heavily stocked koi ponds should size up.
- Low Head models let a smaller, lower-amp pump do the same job.
- Want open-cell media instead of beads? See the GC Tek AlphaONE, the same tank and prices with AlphaBioONE media.
- Not sure which version fits your plumbing? Contact us with your pond size, pump and pipe size and we will help you choose.
