A few good filter(s) and the addition of a wide flow power-head to direct the waste that accumulates on the bottom of the tank is (in my opinion) to the filter intake(s) is best.
Don't overthink it, or you'll spend way more money than you really need to, unless you just want to experiment (which can definitely be fun) and have a fair amount of disposable income to do so with. This hobby can get expensive, and that's not even talking about going saltwater Fowler or Reef.
What I have found is that experimenting is fine, as long as it doesn't come at the detriment of your fishes health.
