as some of your know im looking at all my options for building my new 1000 gallon tank (13x4x2.5T) i am now considering going with acrylic for the viewing window... i know it doesnt seal as easily with silicone but if i use it i will most likley be using the "gasket" method and bolting the acrylic in place every 4 to 6 inches.. first off can i go 36inches tall with 3/4 cell cast? if not ill be fine with only 30 inches tall. and what is a estimated cost on how much im looking to pay for a 12x2.5 or 3 sheet of acrylic at 3/4 thick? i have just spent alot of time on google and i think about $500 to $700 is what im guessing.
