Hi Benny,
A lot of creativity into your machine. Could you, please, explain me what are those wall aquariums? How they are built, and how is built the entirely assembly - wall/aquarium? I never seen such a thing in reality but can not imagine how you mount the aquarium in the house wall and still have access to feed the fishes, change water, etc. Could you, please, explain how the whole thing is built and used?
Thank you.
Zoltan
