The scratches are a night mare which is why it will take a lot for me to get another acrylic tank. Advantages of acrylic to me are
1. The ability to make what would be impossible in glass this includes both shape and size. At the LFS I worked at we sold a few 22 ft long acrylic tanks and it would have been impossible to do them in glass. Bow fronts and bent corners are also easier.
2. Better thermal insulation. This is a real benefit weather in the dessert like me or in a cold climate your heater or chiller will likely work less.
3. Longer lifespan. Glass tanks should be replaced after 15-20 years because the silicon can wear out. Most of us can’t think of having a tank longer than 5-10 years but if you are doing an in wall build and you want the tank to stay there for the next 50 years acrylic is a better bet, just factor in annual buffing.
4. Shatter resistance. Not a big deal for most of us but I helped with a series of installs for a day care center and they were all acrylic. We were just too worried about a kid throwing a baseball and shattering a 300 gallon tank.
thanks for the info! are the scratches difficult to buff out? does it get scratched bad on the inside? im just wanting a rectangle, but the reason I was looking at acrylic is because of the strength, less weight, clarity, and temperature control. would you recommend a glass instead?
