Hi all, just a quick question. I'm looking to add another UV light to my system to give it some help with Algae control. My skimmer pump runs at 3500L/ph and I'm thinking of adding the light externally and feeding the water back into the pond.

Am I better with a light that runs at a higher throughput rate? Is it still effective if you push 3000L/ph through a 4500L/ph light?

Are you fighting green water or growing algae? UV does nothing for growing algae.

I have never used one, plants keep my pond clear and mostly algae free.

A uv light won't fight algae. The nutrients in the pond need to be eaten up by something else, like lots of plants. And if you have fish and are feeding them stop, or slow down.

I have a UV light, but rarely use it anymore. I originally bought it to work on suspended algae particles, it doesn't work on string algae. Honestly lots of plants will help more. I originally couldn't have any plants, as my pond sides are a straight drop and I have koi who munch on everything ! We put it a small bog last Fall , so I'm happily planting now :)
