GC Tek WattMizer KoiKeeper · complete system · 2.5K / 5K / 10K

The simple, no-options koi system

Filter, low-RPM Artesian2 pump and a 316 stainless NishikigoiUV-H80 pre-plumbed on a 36" × 48" all-weather pad. The KoiKeeper is deliberately kept simple — three sizes, no options — so a good system stays affordable. If you live where electricity is tiered, the low-RPM pump is the point: 320–630 watts to run the whole pond. Need a prefilter, a different pump or a bigger UV? Step up to the WattMizer PLUS.

Pre-plumbed at the factory

GC Tek physically assembles every system, marks every union, then breaks it down into boxes. You set the pads, hand-tighten the numbered unions and connect pond in/out.

Artesian2 pumps

Performance Pro external pumps custom-specced for GC Tek — quiet, energy-efficient, 3-year warranty, plenty of power for a proper backwash.

316 stainless NishikigoiUV

Marine-grade 316 (not 304) stainless amalgam UV with individual ballasts, lamp indicators and an hour meter. 13,000-hour lamps.

Ordering & delivery

How long until it ships?

Most GC Tek filters and systems are assembled to order in Chandler, Oklahoma. Typical lead time is about 3 weeks from order to ship, then transit time. Parts and media we stock ship from Upland, CA within a day or two.

Why no freight at checkout?

Freight for a pressure filter or pre-plumbed system depends on your address, liftgate needs and residential vs. commercial delivery. Charging a flat guess would overcharge some customers and undercharge others, so we quote it to the dollar and confirm with you before shipping.

Can I pick it up instead?

Yes — pick up free at Mystic Koi & Water Gardens in Upland, CA. Choose local pickup at checkout or tell us in the order notes and we'll skip freight entirely.

Who handles the warranty?

We do. As an authorized GC Tek dealer we process warranty and parts through the factory for you — no shipping the tank back across the country.
