AquaForte Submersible Amalgam UV
40W and 80W high-output lamps for compatible filter chambers and large pond systems
This category was previously labelled Air Aqua, but the products in it are AquaForte 40W and 80W amalgam submersible UV units. We have corrected the displayed category name so it now matches what we actually sell.
A submersible amalgam lamp is installed inside a suitable enclosed chamber rather than in a conventional inline plastic UV body. That gives a very direct treatment path and keeps external pipe resistance low, but it also makes installation discipline essential. The lamp must never be operated where people or animals can be exposed to UV-C.
Choose between 40W and 80W from the manufacturer’s dose and flow guidance for the real installation. Wattage alone does not describe treatment performance.

40W or 80W AquaForte?
The 40W AquaForte amalgam UV is the smaller option for compatible chambers and moderate flows. The 80W AquaForte amalgam UV provides the higher output for larger ponds or flow rates.
Check the lamp length, chamber clearance, ballast/controller, connector and intended immersion arrangement. A high-output lamp fitted in the wrong place is not an upgrade.
Safe Submersible Installation
Install only in a closed, UV-resistant filter chamber designed for the unit. Water must cover the active lamp as specified. Arrange an interlock or working method that prevents the lamp operating while the chamber is open.
Keep electrical connections dry and protected. Isolate the UV and pump before lifting the lamp or opening the chamber.
Lamp, Sleeve and Ballast Are One System
Amalgam UV performance depends on the correct lamp, quartz protection and control gear. Mineral deposits on the quartz reduce dose; the wrong ballast can damage the lamp or fail to drive it correctly.
Please check before ordering: send us the existing lamp label, connector, controller and chamber dimensions if this is a replacement installation.

Frequently Asked Questions
Are these Air Aqua UV units?
No. The current products are AquaForte amalgam submersible UV units; the old category label was inaccurate and has been corrected.
What wattages are available?
40W and 80W.
Can the lamp sit openly in a pond?
No. It must be installed in a compatible enclosed chamber that prevents exposure to UV-C.
Is a submersible UV fitted into the pipe run?
Not like a conventional inline UV. It normally sits within a suitable filter or treatment chamber.
Can I use any 40W or 80W replacement lamp?
No. Match the exact AquaForte unit, lamp, connector and ballast/controller.
Does the chamber need an interlock?
Use the manufacturer-approved safety arrangement so the UV cannot expose anyone when the chamber is open.
What details help you check compatibility?
Lamp label, connector, control box, chamber dimensions, pond volume and flow rate.
Will a UV clarifier remove blanket weed?
No. UV-C can help with single-celled algae carried through the unit, which is what causes green water. Attached algae and blanket weed need a different approach.
Does clearer water mean the pond filter is no longer needed?
No. UV treatment clumps suspended algae, but the mechanical filter still has to collect it and the biological filter still processes fish waste.
Can I choose a UV only by wattage?
Not reliably. Pond volume, flow rate, fish load, sunlight, chamber design and the manufacturer’s recommended dose all matter.
Why does the quartz sleeve need cleaning?
Limescale and biofilm reduce the UV reaching the water even when the lamp is working. A clean sleeve is essential to useful output.
Can I look at a lit UV-C lamp?
No. UV-C can injure eyes and skin. Isolate the electrical supply before opening the unit and follow the manufacturer’s safety instructions.
Should the UV run before or after the biological filter?
Follow the system and manufacturer layout. The important points are the permitted flow, correct orientation, full water coverage and safe access for servicing.
Can you check which model suits my pond?
Yes. Tell us the pond volume, fish stock, pump flow, pipe size, filter model and whether the pond is in full sun.
When should I replace the lamp?
Use the interval stated for the exact lamp and unit. UV-C output falls with age even when the lamp still produces visible light.
