Aqua Ultraviolet – Ultima II 6,000 Filter with 2" Multi-Port Valve

Overview

Robust, pressurized bead/bio filter for ponds and water features up to 6,000 gallons. The Ultima II 6,000 combines non-clogging media with a powerful cyclonic backwash to keep water crystal clear with minimal routine maintenance—ideal for koi ponds and heavily stocked water gardens.

Key Features

• Bead + biological filtration using high–surface-area Bio-Tubes media

• Cyclonic backwash lifts and purges debris fast—no messy media cleaning

• 2" multi-port valve with simple handle positions (Filter, Backwash, Rinse, Waste, Recirculate, Closed)

• Low head-loss design supports long plumbing runs and external pumps

• UV- and weather-resistant, corrosion-proof vessel for outdoor pads (non-submersible)
