People should not think of an aquarium as something which will inevitable have a foul odour, and which requires special tricks to make it possible to stomach having it in the home. It is not a trick to maintain a healthy clean aquarium, or to avoid overfeeding.
News flash: there is no reason to expect an aquarium to stink. Do some (or most...) fishfoods smell? Yep, absolutely. The aroma is an inevitable result of the ingredients used, and serves to make the stuff more attractive and palatable to the fish. The idea is for the food to be eaten...immediately. The old saw about feeding no more than your fish can eat in 2 minutes, 5 minutes or whatever is correct. My own tanks may be fed only once daily if I am away from home and the feeding duties have fallen upon my wife. When I'm home I will feed several times daily. In neither case will there be food left over after more than a couple of minutes.
Exceptions might include herbivorous fish whose food is grazed upon for several hours after being offered. Vegetable foods of that type tend to be low in odour and slow to decompose, and even then a few hours is the max before I remove the remainders.
A healthy tank should have, at most, a faint natural "earthy-garden" type of aroma; if someone finds that offensive then perhaps keeping fish is not the ideal hobby to pursue...
No, keeping your tank from ever producing a foul odour is the skill to learn, and it is not a difficult task.
