How to build a fish tank?

O ya. I forgot to add that water is 8lbs to the gallon. So 10g is 80lbs plus gravel and decor, you get to 90-100lbs.

I appreciate the concern, but this was one of the first things I checked out. I weigh about 180 lbs, and right after I removed the back panel (note: even less structural integrity!) I sat on top of it and jiggled around just to make sure and... nothin... not even a squeak! Moreover, the bottom tank will basically be supported by the ground anyway since it will be sitting on the bottom panel of the speaker.
 
Ok, now that we have taken care of that, I would go with fish safe epoxy (not the normal stuff) or fiberglass. Its not cheep thought. Look at your local hardware store.

Normal glass will do. 1/8" of an inch for a 10g will be plenty.

The base can be anything as long as its hard, and FLAT and supports the whole underside of the tank.
 
Throughout my research on diy tanks I have found that the minimum thickness for glass is 1/4" for up to 14 in high and if the tanks is taller then 14 it should be 1/2" also make sure that it is not tempered glass. My advice would be fiberglass the inside of the box a few time over and make sure it is as smooth ans even as possible then throw ona couple coats of fish safe 2 part epxy making sure that stays smoot. then silicon the sheet glass on the inside of the box wqhere the whole for the front would be. this would be alot easier, durable, safer adn cheaper then building a whole tak to fit inside the box. and for access you could cut a door on the top and hinge it on using the same wood you cut out.
 
There are definitely cases where one might want to build one's own aquarium.

One may desire a specific dimension of aquarium to accomodate a certain location in their home.

Also, my case is prime example. I wish to have an aquarium that feature intertidal creatures at the various "tidal zones." I want a bit of variety of different creatures which do not all live at the same water level. Some may always be submerged, but others may spend varying times exposed to air as well. To do so requires a fairly tall set-up to allow for the intended changing of the tides.
