GC Tek AlphaONE MegaSystem3 · everything is 3" · up to 30,000 gal

Move a lot of water, and use almost nothing to do it

This is the system you build when the pond is big and the electric bill matters. Every component is 3": the 10.3 filter (10 cu ft of AlphaONE, AquaBead or AlphaNANO media behind GC Tek's Super Hi-Flow 3" multiport), a 3" ArtesianPro pump, and a 3" NishikigoiUV in marine-grade 316 stainless. Friction loss drops off a cliff at 3", so the pump turns 30,000 gallons at low RPM for a fraction of the amperage a 2" system would need. Preplumbed on two all-weather pads measuring 48" x 72".

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.

Also available around the 6.3 filter (6 cu ft) for a smaller all-3" build, and with a variable-speed pump or a PoliGlassBead polishing filter plumbed in at the factory. Tell us the pond and we'll spec it.

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.
