building a new tank

[trevor]

i am thinking of building myself a new tank. just wondering what thickness of glass should be used and if the bottom piece of glass should be suspened or not. the tank will be around the 100 gallon mark. also is this project to much for a first time tank builder. the dimensions i am thinking of are as follows:

dimensions= 48x24x24=120gallon or 48x18x24=90gallon

does anybody know the name of the tank manufacturer out of calgary and if so the phone#
