Thank you all very much for all the help.
I'm not able to reach Sean.
I just came from Fishtown, and they have a 100 g acrylic tank in the form of the divider which is 20 X 48 inches. It has a round/curved front. It is $1,200 (including tax) + $80 delivery, but it is beautiful. We have a friend who is a plumber, and he promised to set-up the plumbing.
I am not sure if the tank will look good in my apartment, but I like it.
Now, about repairing my old tank: It is about 90-95 g, and about 11 years old, I don't know exactly (it is a long story). I know that it was custom made. However it came to me with a LOT of scratches, and now it has even more scratches all over. I don't know how much it would cost me to repair it, and I don't know if it is worth it, since it is old and I am afraid that it may develop more problems. But it is beautiful, an octagon shape = 8 walls, and I love it.
What do you think?
