Acrylic or Glass

[plutoniumJoe]

I know that this probably has been debated before but I am thinking of starting a 180Gal reef. There is a local shop that will build an acrylic tank for me for slightly less than a 180 reef ready glass tank. I like the clarity of acrylic and the ability to drill it easily is a big plus as I might add a closed loop. Some people I have talked to at lfss have been dead set against acrylic. Is there any one in the community who has had an acrylic tank and would caution against it?

I probably wont decide until June but I am trying to gather info.

Thanks for any input.
