One thing I hate in a tank is cloudy water. In short, I want crystal clear water without paying a fortune. I am about to purchase a 180-220 gallon tank setup. I want to run Emp 400s, a UV sterilizer, and possibly a water polisher like the one I mentioned in the heading (which isn't cheap). I have an issue with canister filters flooding my house, so I have found a HOB diatomaceous filter. Basically guys, is it worth it in the long run? I want to only do regular maintenance and not have to constantly fight with cloudy water. I want a proven combination that works like a charm. Is this it?
