Hi all hope this is in the right section
I'm going to start my pond build and am wanting to install a viewing window how ever am unsure on the thickness I would need the pond is going to be 9ftx5ft and 6ft deep 3ft above ground and 3ft below window size I'm hoping to have is 5ftx2ft I have found some aycrlic at 30mm thick do you think this would hold the pressure
Many thanks
