My Dad has one. But its in his sump. Do i have to have a sump for a tank to use a UV sterilizer. I just want to leave it on to g et rid of some Questionable cloudy water. What do i do? I dont have the instruction for it and my dad probably wont let me use it if i ask him.

The only kind i have ever seen has an inlet on one side and an outlet on the other. You hook up your pump to it and run it for a while, but you have to make sure you dont move the water through it too fast, otherwise it wont get a chance to work.
