I've read in several places to turn your UV light off for (so many hours) after adding any type of bacterial product. It's so easy to do - why not?

Yeah, better to be safe than sorry. There's no point cooking bacteria that you've just added to the pond.

You're probably right but not everyone has water going through their UV filter at a high rate of speed. I don't know if that would matter or not. I know ours runs through the UV unit at around 250gph in the smaller 800g pond and you can see a difference in 24 hours. In less than a week it's clear of visible algae.

I was jumping around between different ideas. I don't doubt that UV lights help remove algae. The water speed is probably not an issue in that respect because it's just altering some sugars (I think) in the cell wall that cause adhesion. That has nothing to do with killing bacteria as claimed by the UV sterilisers though. I was questioning whether they are able to effectively kill all bugs in flowing liquid.

On the subject of killing _all_ bugs, do people use hydrogen peroxide producing powders for killing bacteria and parasites. They are supposed to replicate the pumped H2O2 solutions used in fish farms. I spoke to a guy trying to sell some at a UK Koi show, I need more convincing though.
