When picking a uv sterilizer you want one that the bulb housing is no more than 3mm from the housing itself. In other words you don't want the water passing around it to be more than 3mm thick. Also the longer I r is the better and you also don't want the water to rush past the bulb too fast. I'll find the article I read all that on and link it into this post in an edit.

Here it is.
