Re: [APD] UV Question

["Seweryn Bialasiewicz" <s_bialasiewicz at hotmail_com>]

I had a look at some UV sterilisers, as the idea of being able to clean up a 
bacterial or algal blooms, AND clean out the water of potential pathogens is 
quite appealing.

Is the wattage on the bulb relevant to only the velocity of water which is 
pumped through it? Or is there more significance to it, like a lower wattage 
not being able to kill certain kinds of bacteria, etc...

So far I have found a coupole of brands, and was wondering if people had any 
good/bad experiences with them, or suggestions on what brand to get, or what 
to look for when shopping for one.
So far:
Aqua Pro UV Stereliser series
or
Rainbow Lifeguard series
- any of these good?

Cheers,
