Savio UVinex 'High Output' System (For Savio Standard & Compact SkimmerFilters)

Green water hits fast once the weather warms up. One week the pond is clear enough to count scales, and the next it looks like pea soup. The Savio UVinex HO system is built to fix that, and to keep it from coming back.

What the UVinex HO System Actually Does

This is Savio's high output UV clarifier, designed to run inline with a Savio Standard or Compact SkimmerFilter. Water passes through the unit and past the UV lamp, which disrupts free floating algae so it clumps together and gets pulled out by the filter instead of staying suspended and turning the water green.

The HO lamp puts out more UV light than Savio's standard bulb, which matters if algae blooms have been a repeat problem or if the pond sits in full sun for most of the day. When it's sized correctly and run consistently, it also helps knock down parasites and bacteria in the water column, on top of the algae control.

None of this involves chemicals. That's worth mentioning if there are koi, goldfish, small kids, or pets that spend time around the pond, since there's nothing being dosed into the water. Algaecides can knock down a bloom for a week or two, but they don't stop the next one from showing up, and dosing has to be repeated. A correctly sized UV clarifier runs in the background continuously and doesn't need to be reapplied.

Built to Match Your SkimmerFilter

Stainless Steel Junction and Transformer

The housing uses a stainless steel junction, and the transformer is built for continuous outdoor duty rather than occasional use. UV units live outside year round, so the parts that see moisture and temperature swings need to hold up without being babied.

This is the part of a UV system that tends to fail first on cheaper units. A junction that corrodes or a transformer that can't handle running 24/7 through a full pond season usually shows up as a dead lamp or a tripped GFCI within a year or two. Building those parts out of stainless and rating the transformer for continuous use is what lets the unit sit outside through summer heat and winter freeze without needing to be pulled indoors.

Three Wattage Options

The UVinex HO comes in three configurations depending on which skimmerfilter is being used:

• 28 Watt HO, for Savio Compact SkimmerFilter
• 35 Watt HO, for Savio Standard SkimmerFilter
• 55 Watt HO, for Savio Standard SkimmerFilter

Pick the wattage based on the skimmerfilter model already installed, then check it against pond size and flow rate below before ordering.

Sizing the UVinex HO to Your Pond

UV clarifiers get undersized more often than any other piece of pond equipment. Bigger isn't always better either. The unit has to match both the pump's flow rate and the pond's total volume, or it won't have enough contact time with the water to actually work.

Two of the same wattage can be plumbed in a series for larger ponds, or for setups where a single unit is right on the edge of its rated flow. That's reflected in the pairs listed below. If you're not sure which column to trust, flow rate is the one that actually determines whether the algae gets exposed to UV long enough to matter.

Standard SkimmerFilter

• One 35 Watt UVinex HO: up to 2,500 GPH, ponds up to 2,400 gallons
• Two 35 Watt UVinex HO: up to 5,000 GPH, ponds up to 4,800 gallons
• One 55 Watt UVinex HO: up to 4,750 GPH, ponds up to 4,500 gallons
• Two 55 Watt UVinex HO: up to 9,500 GPH, ponds up to 9,000 gallons

Compact SkimmerFilter

• One 28 Watt UVinex HO: up to 2,400 GPH, ponds up to 2,500 gallons

If the pump is pushing more GPH than the UV is rated for, water moves past the lamp too fast to get treated. Check the pump's actual output, not just its maximum rating, since head height and plumbing length both cut into flow.

Installing in an Older SkimmerFilter

SkimmerFilters built before 2007 need a retrofit bracket to mount the UVinex unit, since the housing changed after that. This bracket is not automatically included, so it needs to be added separately if the skimmer predates 2007.

For Standard SkimmerFilters, the bracket is handed for either the right or left side. To figure out which one is needed, stand behind the skimmer facing the pond and note which side makes sense for the plumbing run.

A full installation walkthrough and wiring diagram are in the printed manual, and there's also a video that covers the physical setup step by step.
