The AQUA ULTRAVIOLET A50019 is the Ultima II 2000-gallon bead filter, a biological and mechanical filtration unit designed for pond and water feature systems. It ships with filter media included, ready for installation. The 1.5-inch port connection suits standard pond plumbing configurations. This filter is installed by pond service professionals and experienced water feature contractors who require reliable, high-capacity biological filtration for large ornamental pond systems holding up to 2000 gallons.
The A50019 is suited for large residential and light commercial pond installations where sustained biological filtration is critical to water quality. The bead-filter design supports consistent nitrification and mechanical debris capture in a single unit. The included filter media eliminates a separate purchasing step and ensures the system is ready to cycle from initial startup. It is typically plumbed inline on the return line from the pond pump.
Designed as an OEM-style Ultima II replacement or new-installation bead filter for pond and water feature systems requiring up to 2000-gallon filtration capacity with 1.5-inch plumbing connections.
Installation is performed by pond system technicians or qualified water feature contractors. Shut down all pumps and depressurize the plumbing circuit before connecting or servicing this filter. Standard PVC solvent-weld or threaded fittings are used at the 1.5-inch ports. Follow the manufacturer instructions for initial media rinse and biological cycle startup before placing the system into full service.
