Description
The AlphaONE 10.3 PLUS MegaSystem3 is a complete, all-3" koi pond filtration system for ponds up to 30,000 gallons. Built entirely in 3", it moves far more water with very low flow loss, pairing an AlphaONE 10.3 bead filter and a high-flow PerformancePro pump with the NishikigoiUV amalgam clarifier.
The AlphaONE 10.3 PLUS MegaSystem3 uses the same proven AlphaONE technology as our standard systems, built entirely in 3". Water moves through the huge passageways in the 3" multiport valve with very little loss of flow, so you can move a lot of water on very little energy. It is a complete system for ponds up to 30,000 gallons.
This system now comes standard with the NishikigoiUV Amalgam UV Clarifier, sized to your build, replacing the Zapp Pure units used on earlier systems.

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 3" MegaSystem3 moves much more water than our standard 2" WattMizer PLUS systems, ideal for large, heavily stocked ponds. For smaller ponds, the 2" AlphaONE WattMizer PLUS systems are the better fit.
Frequently Asked Questions
Which UV clarifier is included?
A NishikigoiUV Amalgam UV Clarifier sized to your build, the new standard that replaces the older Zapp Pure units. Because MegaSystem3 is a custom build, contact us to confirm the exact model.
What makes MegaSystem3 different?
It is built entirely in 3", so the multiport valve and plumbing move much more water with very low flow loss. Use it when you want high turnover on minimal energy.
How does it ship?
Built to order and ships by freight. The carrier calls to schedule an appointment, and someone needs to be present to receive it.
