The system that maintains itself

Take a WattMizer PLUS PRO — dual AquaSieve2 prefilters on a 3-port balance valve, an Artesian2 pump, your choice of AlphaONE, AquaBead or AlphaNANO filter and a NishikigoiUV-HD160 amalgam UV, all plumbed on all-weather pads — and have GC Tek fit TheLiberator automatic backwash valve at the factory. Now the filter cleans itself on a schedule: pump off, agitator on, backwash, rinse, back to filter, pump on. Smartphone controllable. Your entire weekly job becomes emptying two prefilter baskets.

Bundled system — call us before you buy. GC Tek prices these as a custom build, and the figure shown here is simply the sum of the individual 2026 components. In our experience the factory's bundle price comes in under that. Call the shop with your pond details and we'll quote it direct from GC Tek, confirm the exact configuration, and tell you the freight before anything is built.

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.
