Yes for me to hide the holow space in the background.
i will also need to build a cabinet on top... ( out of light weight Gibson board with the top open. where i can put the lights and store the food , test kits, etc.
such a pity that you don't have craigslist over there. I just picked up a 5'x1.5'x1.8' (so reverse the height and width) for 50$ and a 29g trade.
what thickness are you thinking on the glass?
I noticed that my 100g with similar dimensions has 1/2" glass while my 125g which is longer and an inch taller has 3/8" glass. both are braced similarly and the 1/2" seems extreme over kill as I've never noticed anything with my 125. either when moving or when in use. So I'd recommend 3/8" with a center brace at the top like both my tanks have. it would be simply adding another 1'x1.8' (less the glass thickness) panel to the build and it would be plenty strong.
Ramzi, whilst i empathize with your desire to build your own tank from scratch, it's simply not worth it here. You can give your measurements to a fish shop get a quote and have them build and test it.
