What about doing the same concept in the pool. Build a viewing area into a corner of the pool and have the rest be the "tank" with a nice greenhouse over the top to help eliminate your heating in the winter. And it's something you could still swim in
I would even see how much a viewing tube would cost.
I always wanted to do soemthing like this but as a saltwater "tank" with something to make a wave for the sound in the greenhouse and create a tropical greenhouse with a seating area and a viewing area down below. just a thought.
