I am planning to build a glass aquarium( for freshwater). i have made some calculations from aquatools.com, this is the link
Calculate Aquarium Glass Thickness | Aquarium Tools
the size of the aquarium will be L:120cms, W:40cms, H:50cms, capacity:240 liters. glass thickness coming to 9mm.
can anyone advice me about the size of the tank. are the dimensions okay or do I have to vary the dimensions. do I have to keep the safety factor to 3.8 or can i vary it. do i have a side brace in the tank also.
any advice on the silicon to be used. is it required to be of some particular strength and is it a food grade silicon.
Can i have the edges of the glass polished, if so will the silicon hold it.
