Filter parts

[kevinwbd84]

Hi I moved in to a property with an existing pond the uv filter doesn't seem to work so I was going to replace some parts I have already tried a new bulb and doesn't work. So was going to replace the fitting and renew the glass gaming and couple other bits problem is it is an older system I feel as if it says a jebao gf-30 but that doesn't seem to exist so does that mean it has to be the cf-30 or is it just a discontinued product
Thank u very much for any help u can give
Kind regards

Why do you feel the uv isn't working? What filtration do you have?

9 out of 10 uv units have a pin hole viewing window that allows you to see if the light is on or not.
