I am just getting back into the hobby after about ten years without any tanks. However, for the previous 15 yrs, we had as many as 40 tanks going at the same time, acrylic and glass. Glass is great on price and being scratch free, but the leaks happen sooner or later as does the unexpected crack/breakage. (especially with grandkids) Acrylic is more expensive, but with what I feel is a better appearance, lightweight, easy to move, and when you look at it wrong it scratches. When cleaning on the inside, I use pre-washed chami cloths or regular washcloth for those scratches that grew algae.
