Description
The WattMizer KoiKeeper is a value-focused, complete koi pond filtration system for ponds up to 10,000 gallons, pairing a pressure filter with an energy-efficient Artesian2 pump and the 80-watt NishikigoiUV-H80 amalgam UV clarifier. GC Tek builds and glues the 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 pad, match the numbered unions (1 to 1, 2 to 2), hand-tighten, and connect to your pond. The plumbing work is already done for you.
Every KoiKeeper now comes standard with the NishikigoiUV-H80 Amalgam UV Clarifier, replacing the ZapTek2 units used on earlier builds.

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.

Frequently Asked Questions
Which UV clarifier is included?
The NishikigoiUV-H80 Amalgam clarifier, the new standard that replaces the older ZapTek2 units. Amalgam lamp technology gives higher UV output and up to roughly 13,000 hours of lamp life.
What makes the KoiKeeper a budget system?
It pairs the same quality bead filter and amalgam UV with the energy-sipping Artesian2 Low RPM pump, so it costs less to buy and less to run while still keeping water clear.
