AquaForte Pond UV Clarifiers

Three useful outputs for garden ponds, koi systems and higher-flow installations

This category contains the AquaForte Power UV TL 30W, MIDI Power UVC 75W T5 and Power UV TL 110W. The 30W model suits modest pond systems, the 75W MIDI provides a strong middle option, and the 110W unit is aimed at larger volumes and heavier clarification duties.

A UVC works on water that actually passes through its chamber. It helps suspended green-water algae clump so the filter can capture it, but it does not vacuum debris, process ammonia or remove blanket weed from the pond wall.

Wattage is only half the decision

Contact time, chamber design and installed flow all affect results. A powerful lamp connected to a pump that sends water through too quickly can still disappoint. We compare pond volume, sunlight, fish load, filter flow and the manufacturer’s recommended exposure rate.

Plan the service parts before installation

Every pond UVC needs lamp and quartz-sleeve maintenance. Position the unit where it can be safely isolated, drained and opened without dismantling the plant room. Also identify the exact replacement lamp and seals for the model rather than assuming wattage alone guarantees compatibility.

Choosing an AquaForte UV Unit

Power UV TL 30W

The 30W model is the compact route for garden ponds and smaller koi systems with a realistic flow. It is often a better fit than installing an oversized unit with unnecessarily large connections.

MIDI Power UVC 75W T5

The 75W T5 model bridges the gap between small conventional clarifiers and the 110W unit. It suits customers looking for stronger UV output without moving straight to the largest AquaForte option on this page.

Power UV TL 110W

The 110W model is intended for larger systems and higher flows. At this level we pay particular attention to the filter, hydraulic layout and ongoing lamp cost rather than selecting from pond volume alone.

What we need to recommend one

Send the pond volume, fish stock, hours of direct sun, pump flow and existing filter. If the water is brown with suspended silt rather than green with algae, a UVC may not be the missing piece.

AquaForte Pond UV Clarifiers FAQs

Which AquaForte UVC models are listed here?

The Power UV TL 30W, MIDI Power UVC 75W T5 and Power UV TL 110W.

What is the difference between the 30W, 75W and 110W units?

They provide different lamp outputs and suit different flow and pond-size duties. The chamber and lamp format also differ between product families.

Is the 75W T5 lamp the same as a 75W amalgam lamp?

No. Lamp technology, size, ballast and connection must match the exact unit. Order spares by model, not wattage alone.

Will the 110W model clear water faster?

Only if it is correctly matched to the flow and problem. More wattage does not fix poor filtration or water bypassing the UVC.

Can these units be used on a gravity-fed system?

Suitability depends on the exact model, pressure, installation position and flow. Follow the product instructions.

How do I know whether the quartz sleeve is dirty?

Isolate and inspect it safely at the recommended service interval. Hard-water scale may be present even when the outside of the unit looks clean.

Can you match the replacement lamp?

Yes. Send the full model name and, ideally, a photograph of the rating label.

What does a pond UVC actually do?

It exposes passing water to ultraviolet light, helping suspended green-water algae clump so the filter can remove it. It is not a substitute for mechanical or biological filtration.

Will a UVC remove blanket weed?

No. Blanket weed is attached to surfaces and does not pass through the chamber in the same way as suspended green-water algae.

Why does flow rate matter through a UVC?

Contact time matters. Sending water through too quickly can reduce exposure even when the lamp wattage looks generous.

How often should I replace the lamp?

Use the manufacturer’s service interval. A lamp can still glow visibly after useful UVC output has fallen.

Why clean the quartz sleeve?

Limescale and dirt block UV transmission. A clean lamp behind a dirty quartz sleeve will still underperform.

Can I look at the lamp to see whether it works?

Never view an energised UVC lamp outside its closed housing. Use the safe indicator and isolation procedure specified for the unit.

Can the UVC be installed after the filter?

Some systems allow this and others specify a different order. Follow the hydraulic layout and maximum-pressure guidance for the exact equipment.

Can you match a UVC to my pond?

Yes. Pond volume, fish load, sunlight, required flow and the existing filter all help us recommend a sensible model.
