When using Interpet Sludgebuster or any other of these sludge clearing
bacteria agents is it necessary to turn off the UV ?

I'm wondering if the UV will kill off the useful bacteria.
==================================

The useful bacteria are mainly on all pond surfaces and in your filter. Not
many are in free in the water. It's better to turn off the lights when you
add bacteria and give it a chance to settle. Leave the UV lights off for a
least 24 hours. No use adding them and then killing many of them off as
they go through your UV light unit.
