Ok, so Im looking at maybe getting this UV sterilizer, which I was recommended by daryl. I found one on this site:

http://www.marineandreef.com/shoppro/sterilizers_Turbo.html

now I was thinking of getting the turbo twist 3X, and the rio 400 pump, it says I need a hose, either 5/8" or 3/4", but which one will I need?And it says that u need at least 4 feet, but their sold as 1 foot, so do u buy 4 of those?

then on the first page at the bottom theres some weird connector thingies for the UV and the hose, do I need those too?
