Its not AGGI its algae and buoyancy is not the same thing as bouncy   


I would do something like this : http://www.instructables.com/id/Fish-tank-cleaner/

Then on the outside I would have a car with a magnet driving the cleaner around form the outside ( with the cleaner on the inside)


How can it use it s own buoyancy ? Meaning you  want to change the buoyancy ( submarine) to clean the tank?  Thats a bit difficult!

use a robot arm on outside and magnet on it...then magnet on cloth or somthing...anyway good luck
