I will add that Acrylic does not distort light as much as glass. Looks more natural. But, with that said, I have always used glass because of the scratching issue. Weight is also a factor. Glass is heavy. I have a 240 glass and it nust weigh 400lbs emptyIt took three adults and two boys to move it onto my stand. There are some good resources on the web for drilling goles in glass aquariums.
