Is there any problem with bonding black acrylic to clear? If I go with acrylic I would like the bottom and sides to be black with a clear front. Adhesion qualtities, strength etc., the same? I like the look and it seems it would save money as well. Also I wasn't clear--did you use acrylic glue, or the two part polymer process that welds the pieces together. I just read the thread about the 450 gallon tank that blew apart and I want to avoid similar problems. Thanks!
