The "way to go" for having clean aquariums?

Since this is posted in a community called "Aquariums and Fish Keeping", that would be my first guess.

No no, you don't understand we just need to put all the cities in aquariums make it like a bikini bottom type situation and then we can clean pollutants

For personal aquariums. A lot of these systems are fractals, big or small. Grasses should help keep aquariums cleaner, too.
