If the plexiglass is mounted in slabs over two Buckminster Fuller
structural domes it can cover as much as 1000 square meters.
In this case the liquid can be more dense than water and with
greater refractive index .

Would you care to calculate the pressure on the plexiglass and estimate how
thick it would need to be.

Precisely. The steel structure will support the weight of water. The
curved
slabs are small say, four square meters .
Supposing a maximum gap between domes of 2.5 meters, I think its
thickness
maybe of half an inch.
Polycarbonate is stronger and translucent than plexiglass.
