UV sterilizers worth it?

[biboybaka]

are uv sterilizers good for freshwater? do they really work like miracle? im thinking of getting one for my new 300 gal. could it lessen water changes?

 

[Alexandrian]

A good question

No, it won't lessen waterchanges. All it will do is help prevent parasites, and kill green water.

Won't lessen water changes, but very good to have and will prevent many potential problems with the fish.

It will make your water clearer if you have cloudy water.

yes they work great a claering the water but the won't prevent or lesson water changes.

There's a pretty good explanation of how UV sterilizers work here - http://www.peteducation.com/article.cfm?c=16+2148&aid=2855

I will never be without a UV for my aquariums, ever. The difference they make in water clarity and algae control, not to mention parasite control, you wont be sorry in getting one. Set up properly, they are cheap insurance.
For a 300g I would go with a 36W@3-400gph.

Totally agree with boldtogether. They do what they do well and are a great addition to any setup
