pond window

[john4evr]

is there a formula for finding thickness for acrylic window? Approximately 400 gal. behind window that is 42"w X 20"h
Will be siliconed to cement wall on three sides with top exposed just above water level.
Anything below I believe does not matter.

the real trick is making sure the window is adequately supported around the perimeter. the edges ans seals are more likely to fail than the panel itself

a supporting rim on the outside is MUCH better than trying to seal it on the inside surface
