Does anybody have any experience with a canister filter that also has a UV sterilizer? I am thinking about adding one to my 75g. I have heard of some benefits of having one but would like to hear some people that have experience with them. So the end question would be is it worth it? why or why not. This link is the one im thinking about for my 75. I already have one sunsun, the one without the UV sterilizer.http://www.amazon.com/SunSun-HW-402...ilizer/dp/B00C8SK62O/ref=cm_cr_pr_product_top
