Hi there. I have a problem with my Pond UV, its a Oase Bitron 25W and although there is power at the tube the tube wont light up. Have tried 3 tubes so its not a tube problem. Has anyone any ideas on this please. Thanks in advance, Alan.
Thank you 2010 for your reply. The first three of your suggestions have all been checked and eliminated, however your 4th suggestion was one I had not even thought of. As the unit is now a few years old and the ballast unit is no longer made I have just ordered a new UV off Ebay. Thanks for your help. Alan.
