High-Capacity Filtration for Medium-to-Large Ponds

All AquaBead filters utilize the Omnifuser design technology that eliminates slotted PVC pipes in the filter. The Omnifusers allow the heavier solids to be easily purged from the bottom of the filter during backwash since they are sitting at the lowest point in the filter.
The 4.25 cu. ft. AquaBead 4.25 is the perfect filter for ponds up to 10000 gal. and fish loads up to 225 lbs. Flow rated at up to 90 gpm for bio-mechanical filtration. 24.5" X 35.5" allows you to hide this unit anywhere. Every option is standard equipment. It is the perfect filter for the majority of ponds.
AquaBead filters also feature the AquaBead Life Support System, known as "ALISS", which keeps beneficial bacteria alive indefinitely during medical shutdowns, pump failures, etc. The 2" Clear Union Spring Check Valve located right under the 2 HP blower provides maximum flow and has built-in unions.

Been running this filter for 6 months now—zero issues and outstanding water quality. Set it and forget it.

My fish are healthier, and the algae is finally under control. Maintenance is quick and painless.

One of the best upgrades I've made to my pond system. If you’re on the fence—just get it.

Heavy, durable, and efficient. It runs quiet and keeps my pond balanced even in the summer heat.

Great investment for larger ponds. I paired it with a 1/2 HP pump and it’s a perfect match.
