Help with UV sterilizer

Okay ive been looking aorund at the UV sterilizers, i was told it would help with the slight cloud my tank gets every so often
I have no clue how to use one without its own pump
I was looking at this Internal UV Sterilizer w/Power Head & Lamp Replacements - Sale - Fish - PetSmart
Has anyone used this?
And i this will not help me is there a uv sterilizer out there with a pump attached?

 

i have mine plumbed into my effluent of my canister filter

 

I don't know how to do all of that. And I have an aquaclear..well three of them. I guess this one at petsmart won't work for me?

 

It looks like this one is designed to be placed in the tank or in your sump as opposed to being on a closed loop.

Thread moved to proper forum. The ASAP forum is for time-dependant emergencies only

 

Being placed in the tank is fine. But will this one work for the milky cloud in the saltwater tank. (I only have a slight clodyness every so often)

 

that model is an insump or intank model. you don't have to worry about plumbing or tapping into your system. just drop it in tank (fully submersible) and plug in and you're set.

 

I would get one with a wiper if possible to keep the quarts sleeve clean for best performance.
