UV on new pond

[ErikvR]

Hi all,

My new pond has been running for about 2.5 months and the water is starting to turn slightly green.

I was just wondering if it might be time to switch on my UV for the first time.
Or is it better to leave it off while the pond is finding its balance?

I don't have a uv because as I understand it kills beneficial things as well as algae. It takes a few years for the pond to balance out. Lots of plants will help filter the water. Good aeration and less feeding of any fish I only feed once a week. I have algae in my pond and I just ordered an Oase BioTec Filter to help my pond as I have about 50+ goldfish one koi and more fish coming.

UV only kills floating single celled organisms. And when you kill those off you're left with dead floating single celled organisms in your water. Which feeds more algae.

All you had to say was "new pond". Wait and see what happens.
