Now for the tank...
IMO there are three major steps to building the tank. I am still on the first one.
1. Assemble the tank
The plans at dudeiknow.com call for 3/4" exterior grade plywood. I went with 3/4" plyform which is what is used in setting up concrete walls. The plys seemes a lot tighter in the plyform that the exterior grade plywood. You could go a step higher and get marine 3/4" plywood which is almost $70 a sheet at my local lowe's. I think the exterior would work fine, just more of a personal choice. 3 sheets of plyform cost me about $150.00. And like i said earlier, i used the leftover to help box in my stand and make it more heavy duty. You will also need a good waterproof wood glue and a box of 2" drywall screws. The assembly is pretty obvious if you follow the plans on garf. They have step by step illustrations to guide you so i will save myself the time.
2. Paint the tank.
This is a very very very important step. This is what will make your plywood tank waterproof. You will need to find a NSF-61 rated epoxy paint approved for potable water storage. IT is very important that this paint is marine safe. Otherwise you will just kill of of the tank's inhabitant's. They make tons of different epoxies. Some for concrete, some for wood, etc. Be sure you get the right one. After searching this website for a cheap supplier of this paint i finally found an answer.

This place has a wide selection of colors and they are all $48 for a 1 gallon kit. I think the shipping is an additional $20 for a HAZMAT fee but well worth it IMO.
3. Install the glass
This is the most expensive part of the project. My roommate is good friends with the owner of a local glass store so i kind of lucked out. Originally my lowest qoute for a 1/2" x 72" x 29" piece of glass was $230. He got it for me for $99.
I am not going into great detail at this with steps 2 and 3. But will as time goes on and i approach each step.
