Hi guy,
I may want to try diying a small sump tank of 40x28x34cm with the thickness of 4mm or 5mm acrylic sheet but was discouraged by the guy from
Ying Kwang Acrylic Trading. He adviced me to use 10mm instead as reason given was tank will forge after addition of water.
What do you guy think? Should I go ahead for 4mm or 10mm?
