UV Sterilizer

[Habs33]

Hello everyone,

I find my water is starting to have a green colour. I research some last night and found using an UV sterilizer is an option.
Has anyone used one? What were your results? Can you use it with the fish in the tank or will it harm the fish?
Thanks for your time.

UV's work great for green water. Only need to run them for about a week and remove it when it's all cleared up. No harm to anything.
