Ohh...tks for the clarification...
I went there on a weekday afternoon...the staff was very friendly i just told the guy on the first floor that i wanted to buy acrylic and he directed me up to the 2nd floor where the sales ladies are.
U just need to give them ur dimension and they will cut for u the acrylic...they got different type of colors to choose from and have sample so those who dunno what they want can choose from it.
But 1 thing different is that extra work such as rounding of edges requires extra money...i rounded my edge for additional $5 if i remember correctly.
As for the acrylic i put in my tank for 2-3 months and so far no warping and fishes are still swimming happily.
The acrylic will get sticked to the tank base as mentioned by other bros and i recently just lifted it up using some suction cups and thread to clean and am quite surprised to find little to no dirt stuck underneath despite having not cleaned it for 2 months.
Above just sums up my exp...
