Sunsun AUV-08A Submersible UV-C Sterilizer Lamp (8W) – Algae Control for Aquariums & Ponds
The Sunsun AUV-08A is an 8W submersible UV-C steriliser lamp for aquariums and ponds, used to clear green water, control free-floating algae, and reduce waterborne bacteria and parasites for clearer, healthier water. It is not a display or plant-growth light — UV-C is a germicidal wavelength that works as water passes the lamp, killing the algae and pathogens that cloud a tank. A practical fix for persistent green water that lighting changes alone will not solve.
Why choose the Sunsun AUV-08A?
- UV-C sterilisation that clears green water and free-floating algae.
- Reduces waterborne pathogens — bacteria and parasites — for healthier fish.
- 8W submersible design for aquariums and ponds.
- Clearer water without dosing chemicals.

What it does (and does not) do
A UV-C steriliser is a water-clarity and health tool, not a grow light or display light. It will not grow plants or light up your tank for viewing — for that you need a display or planted light such as the Sobo AL-480. The UV-C lamp tackles the green-water and pathogen problems that a display light cannot. Learn more in UV light for aquariums explained and how it fits algae control in aquarium light settings to prevent algae.
How to use it
Run the steriliser submerged with water flowing past the lamp, typically alongside your filter. Use it to clear a green-water bloom or as ongoing clarification; many keepers run it periodically rather than continuously. Always connect with the power off, keep the adaptor above water, and use a drip loop. Replace the UV bulb periodically, as germicidal output fades over time even while it still glows.
Frequently asked questions
What does a UV-C steriliser do?
It kills free-floating algae (green water) and reduces waterborne bacteria and parasites as water passes the lamp, giving clearer, healthier water.
Will it grow my plants or light my tank?
No. UV-C is a germicidal tool, not a display or grow light. Use a separate full-spectrum light for plants and viewing.
Does it remove algae on glass and decor?
It targets free-floating algae (green water), not attached algae on surfaces. Pair it with good light discipline and maintenance.
Can I use it in a pond?
Yes. The 8W submersible lamp suits both aquariums and ponds for water clarification.
How often should I replace the bulb?
Periodically, as UV-C output declines over time even while the lamp still lights. Follow the maker's guidance.
