Could you tell me why my Oase Bitron 25 bulb is not working but there is power going to it (I have tried a different bulb)?

Dear Stephen Thank you for your question. The ballast unit may of developed a fault. Bear in mind that if you are trying to test the bulb outside of the main unit it will not light up due to a safety device and the unit needs to be fully assembled to test.

If a new UV tube in a Bitron 25 unit lights does it mean that it is emitting UV light? or could a new tube be faulty?

Dear Tom Thank you for your question. A new bulb should be emitting UV light if it lights up and will last around 6-9 months. It is very rare a UV is faulty.

How do I change the glass tube on a Bitron 25? Is there a manual available?

Dear Thomas Thank you for your question. The screws shown in the exploded diagram need taking out and this will give you access to remove the quartz, Unfortunately, as these have been discontinued, we do not have the manual.

I have just installed a new tube in a Oase filter + a Bitron 15 UV, but this being my first pond, I don't know how to tell whether it is working. As the Oase website does not offer a comprehensive range of downloadable PDF manuals, can you advise?

Dear Gary Thank you for your question. Once the unit is put back together there is a viewing window on the back of the unit that should glow blue at night if it is working. As this product has been discontinued for over 10 years manuals are no longer available from the Oase website.

Do I need to change a filter on a Bitron 15 pond filter system or carry out any regular maintenance? I use the system at least 3-4 times each week for a few hours each time and it seems to work OK in my pond. The fish don't seem to be complaining anyway although I do get a build up of green slime and surface algae from time to time which needs to be cleared.

Dear Neville Thank you for your question. For a UV to be effective it needs to be running 24/7 during most of the year and then can be switched off during the winter months.

Why does the blue light flash on my Briton Oase?

Dear Yvonne Thank you for your question. The bulb may need changing or the ballast unit might be on the way out. I would try the bulb first.

I have purchased and fitted a new UV tube but it appears not to be working as the water in my pond is still green after more than a week. How can I check whether the new UV is working?

Dear Anthony Thank you for your question. If a UV system has a backlog of algae to eradicate it can take a good couple of weeks to clear. However, if you wait until dark the hose tails on the unit should glow blue if the bulb is on. Should you wish to contact us further or to place an order, please call us on 0121 355 7701.
