Old UV bulbs
 

Well I just guess you do what works for you and if it means moving the
thing from pond to pond and you are happy to do this then that is fine
for you.....personally having read up on UV in research for my new
pond...and having a husband that kind of has specialised knowledge in
this stuff - I guess I will go with him and the concensus of others
posting on this thread.....

What works for you may not work for others.....therefore these advisory
life spans are put for a purpose.....it is not possible to make the
statement that these bulbs last for 6 years in all applications.....

Continued use of a functional bulb makes sense to me.

Would there be any device that would allow us to assess how good or bad
our
bulbs are? I would hate to throw one out with 75% efficiency. For that
matter 20% if it still handled the load in my pond, why change it? Maybe
that is the best answer. If it works, don´t change it. Tho somewhere the
cost of running and inefficient bulb must come to the price of replacing
it .

Does anyone have an idea how to assess the efficiency and cost factors?

Well...... in my non-UV-using opinion, I'd say when your pond starts to
turn green would be a good indicator. ;-) ~ jan

That may also indicate the bulb's sleeve needs cleaning, or you hooked it to
a faster pump pushing water through it too quickly.
