Ho right, I’m asuming alot people run them all year round them from the responses! I didnt see the need myself as for the low light and no algae... this is my first winter though so still learning . That said only now have I just noticed a green colour and plants in garden are cuming alive so good indication

My pond has polycarbon roof permanently with uv diffuser in the roof so I probably don't need one but it gives me a little peice of mind, also my mindset is the less you turn things on and off the less chance of wear and tear or failure, the uv I have on it has been on constantly for about 9 years now and only goes off for bulb changes

Yep just leave mine on and change the bulb around May time annually so it’s at full power for summer. Really just personal choice, I think my pond would remain clear without on during winter...but I always change the bulb each year, and happy to ‘run it out’ over the winter months..

I run everything 24 / 7. UV air pump the lot.
Even in winter. With covers on.

charco123,
Your UV does more than just stop green water, it helps to eradicate many of the nasties that you cannot see. Leave it on all year. I have got two, one in my RDF and one before the water goes back into the pond from a sump. My water never goes green.

Green water uv
Just been reading that even though UVs are sterilising units doesn’t mean that it would take any effect on irradiating nasties or parasites .... and then I read another site that says it does kill parasites... seems a gray area ? Il run all year from now on I rekon but don’t think it hurts to turn off in winter either.

Running heater at low temp?
Covering the pond with polycarb should be enough to stop water temps dipping below 6C for the most...
