GCTek WattMizer PLUS PRO Filter Systems
The GCTek WattMizer PLUS PRO Pond Filter System is GC Tek's lowest-maintenance koi pond system. Dual AquaSieve2 prefilters take the bottom drain and skimmer lines, a 3 port valve balances flow between them, and the water then runs through an Artesian2 pump, your choice of AquaBead, AlphaONE or AlphaNANO filter and a NishikigoiUV-HD160 Amalgam UV before returning to the pond. GC Tek says weekly care takes about 5 minutes: empty the AquaSieve2 baskets and backwash the filter.
• Six Sizes: WPP1.75 to WPP10.0, plus the WPPX210.0 with two pumps on one X2 filter.
• Dual AquaSieve2 Prefilters: One for the bottom drain(s), one for the skimmer(s).
• 3 Port Valve: Balance bottom drain and skimmer flow by turning one handle.
• NishikigoiUV-HD160 Amalgam UV: Standard on every PLUS PRO system (two on the WPPX210.0).
• Plumbed by GC Tek: Built and test-fit on 48″ × 72″ all-weather pads, connections marked, then boxed for shipping.
