Welcome to AquariumAdvice.com!!!
First off...there is really no good "all-in-one" system. Your (and your tank) are better served by reserching and buying seperate components.
I am looking for suggestions on a quality, low maintenance filtration system which incorporates everything.
, go with 1.5-2lbs/gal
substrate and aggressive skimming. This will give you great all natural filtration. Some people do throw in a canister or HOB
filter as a means of mechanical and chemical filtration. These do need to be cleaned often to keep water parameters in check. Another option is going with a sump or fuge under the tank.
