I posted this on RC  but nobody has answered.  Want to get started on this ASAP, so the quicker the help the better. 
 
Thanks in advance guys?

 Metric makes this alot easier, so first lets convert..
24 in = 61 cm
24 in = 61 cm
18 in = 46 cm
61 x 61 x 46 = 171166 cm*3 (centimeter cubed)
171166 cm*3  = 171166 ml
171166 ml = 171 litres
171 litres of pure water = 171 kg
171 litres of water (salinity 1.024) = 175 kg
So each tank weighs 175 kg or 385 lbs when full, acrylic is neglible.
I would say no, 1 x 2 wood is not able to support this weight, go 2 x 4.
