UV Bulb

[paulh]

Hi,


I have your AAP/SunSun CUP-613 UV ump and just purchased from you a new bulb. Just wondering how I can tell if the bulb is working
(other than waiting for water to clear) since my last one died although I couldn't tell other than my water did not clear as it did in the past.


Any help would be appreciated.


Thanks,


Paul

Paul,

You should be able to see the ring around the unit be UV blue in color. Checking in the dark sometimes helps.

Here's a picture example.
