Evolution Aqua Evo UV 75 Watt

Maximum UV Clarification for Extra Large Garden and Koi Ponds

The Evolution Aqua Evo UV 75 Watt is the highest output model in the Evo UV range, designed to eliminate green water in ponds up to 75000 litres. It targets free floating algae directly and, as a result, restores clarity quickly even in large or heavily stocked systems.

This upgraded model features a powerful 75 watt T8 UV lamp combined with a re engineered internal flow chamber. Because water passes evenly around the quartz sleeve, the unit maximises ultraviolet exposure and increases algae neutralisation efficiency. Consequently, it provides strong and reliable clarification in extra large garden ponds and koi ponds.

With a recommended maximum flow rate of 25000 litres per hour, the Evo UV 75W suits large filtration systems and high turnover setups. When you integrate it into a balanced mechanical and biological filtration system, it delivers consistent performance and supports long term water quality.

The unit includes an energy efficient electronic ballast and a protective quartz sleeve to ensure optimal UV transmission. In addition, you can replace the UV lamp, quartz sleeve or ballast quickly, which reduces servicing time and keeps downtime to a minimum.

Installation remains flexible. You can mount the Evo UV 75 Watt horizontally, vertically or at an angle using the supplied brackets. It connects via 1.5 inch inlet and outlet ports and includes threaded hosetails for flexible hose compatibility. Alternatively, you can hard plumb it into rigid pipework systems.

When paired with Evolution Aqua filtration systems such as the Nexus, EazyPod or Tempest, the Evo UV 75W becomes a powerful component within a complete pond filtration setup.

Choosing the right pump setup

When choosing a pond pump, the number on the box is only the starting point. Real flow is affected by head height, pipe length, bends, hose diameter, valves, UV units and the filter it is feeding. A pump that looks powerful on paper can lose a lot of performance if it is pushed through undersized hose or a restrictive run of fittings.

For best results, plan the pump, filter, UV and return pipework together. Use larger bore hose or pressure pipe where possible, keep bends sensible and leave enough access to remove the pump for cleaning. This gives the equipment a better chance of delivering the flow the pond actually needs.

Before you order

Check the product size, connection details, access requirements and the equipment it will be used with. On ponds, the surrounding system often decides how well the product performs. Suitable pump flow, clean filters, correctly sized hose or pipework, good access for servicing and realistic maintenance all help the product work as intended.

Maintenance and compatibility checks

It is worth checking the supporting parts at the same time as the main product. Hose size, pressure pipe, valves, unions, UV units, filter inlets, air manifolds, spares and cleaning access can all affect how well the final system works. A correctly matched installation usually performs better and is easier to maintain than one built from parts chosen separately.

Product choice checklist

Before buying, double check the product against the way the pond is actually set up. Look at the water volume, fish load, flow rate, pipework, filter position, service access and the parts already installed. A product that is correctly matched to the system will usually be quieter, easier to maintain and more reliable than one chosen only because it has a higher rating.

This is especially important on koi ponds and larger garden ponds, where pumps, filters, UVs, air systems, food, treatments and fittings all affect one another. Taking a little time to check compatibility before ordering helps avoid restricted flow, awkward maintenance and unnecessary returns later.

Best results in the pond

Evolution Aqua evoUV 75w should be used as part of a sensible water quality routine. Treatments work best when the pond is correctly filtered, well aerated and tested regularly. Before adding any pond treatment, check the pond volume, read the dosage instructions and consider recent changes such as heavy rain, filter cleaning, medication, water changes or new fish.

• Measure the pond volume as accurately as possible before dosing.
• Use water tests to understand the problem before treating.
• Keep filters and aeration running unless the product instructions say otherwise.
• Allow time for the pond to respond before repeatedly adding more product.

Good pond care is usually a combination of filtration, testing, sensible feeding and the correct treatment at the right time. That approach gives more reliable results than treating symptoms without checking the cause.
