Just curious, would it be possible to make a big enough tank so you dobt have to do maintenance.

I always thought if I was a gazillionair I would build a house on the beach that had a below water level room with a giant window into the ocean. You could even aquascape the rocks and place corals like a tank, just in the ocean!

You would have to clean the glass. i.e. no to the original question.

On the contrary, if I had that much money I would have servants to clean the glass. Ergo, no maintenance.

with enough $$$$, many things are possible.
