Re: NFC: Aquariums

   I have 2 300 gallon plex tanks 96"long x 24" wide x 30" high.They are
made out of 1/2" plex except for the top which is 1" thick which is the key
to keeping the bowing of the sides to a minimum.The top is made out of many
pieces of 1/2" plex all laminated together.The back and ends have a 6" band
of plex and the front is 4". The three cross braces are 6" leaving three
14"x24" holes in the top.Hope this helps.
