WattMizer PLUS PRO Systems

The WattMizer PLUS PRO is GC Tek's top-tier koi pond filtration system for ponds up to 30,000 gallons. It pairs your choice of pressure filter with a Performance Pro pump, the NishikigoiUV-HD160 amalgam UV clarifier, and dual AquaSieve2 prefilters on a 3-port valve that balances flow between the bottom drain and skimmer circuits. GC Tek builds and glues the entire system at their facility and numbers every union, then disassembles it into labeled, pre-fitted sections and ships them in separate boxes so it travels safely by freight. Reassembly is simple: set the pieces on your pads, match the numbered unions (1 to 1, 2 to 2), hand-tighten, and connect to your pond. The hard plumbing is already done for you.

The WattMizer PLUS PRO Series by GC Tek is the top-of-the-line solution for koi keepers who want nothing but the best for their fish. This all-in-one system starts with dual prefiltration: two AquaSieve2 units handle both the bottom-drain and skimmer circuits, and a 3-port valve lets you balance flow between them. The system is powered by an energy-efficient Performance Pro pump backed by a 3 year warranty, with your choice of AquaBead, AlphaONE, or AlphaNANO media.

The final stage is the NishikigoiUV Amalgam UV Clarifier (the NishikigoiUV-HD160), our new standard for clear, healthy water. It replaces the older ZapPRO high-output UV used on earlier builds. The system is built to order, then labeled, disassembled, and packed for safe shipping, so it reassembles in just minutes at its final location.

The Models

What's Included

• Two AquaSieve2 prefilters (bottom-drain and skimmer circuits) with a 3-port balancing valve
• Your choice of AquaBead, AlphaONE, or AlphaNANO bead filter media
• NishikigoiUV-HD160 Amalgam UV Clarifier, the new standard UV

• Pre-plumbed on all-weather pads, built with two check valves

Why the NishikigoiUV Amalgam Clarifier

Amalgam lamp technology produces far more usable UV than a conventional clarifier lamp, so the same unit clears more water in less time. The lamp runs up to roughly 13,000 hours between changes, and the housing is marine-grade 316 stainless steel built to last in a pond environment.

How It Compares

The PLUS PRO is the flagship. It adds dual prefiltration and a second check valve over the standard WattMizer PLUS. For a simpler or more budget-friendly build, see the WattMizer PLUS or KoiKeeper systems.
