swater,
FWIW, I have a 150 gal acrylic, and would hesitate to ever have one again. Glass can easily be scraped clean, and is not as easily scratched. Knowing what I know now, I might have less problems with acrylic, but since I can't see through the bottom 3" of my tank, it is hard to give in to acrylic again. With this all said, it does have advantages in being less prone to crack, more easily moved, and clearer. hope this helps. Adam

When did this become a habit instead of a hobby???
