The UVC should be cleaned every 6 months and the bulb changed every 12 months so they are probably much better these days and kill any ‘nasties’ which are floating in the water column. Apparently after 12 months the bulb has lost 70% of its original power and hence the reason to change it.Shaun,
That's a great update and thanks for sharing.
I have not ran a UV unit since the mid 1990's. Back then you replaced the UV bulb about every 90 days ;Oldman
How often are you supposed to change out a UV bulb now?
I’ve run one pretty much since I started out as I just think anything that can help prevent potential diseases with the inhabitants must be a good thing and it also helps with the clarity of water.
I haven’t had any issues with temperature increasing or anything at all with it. Well as far as I know! Lol
