LOL... didn't realize we have kids doing reefs these days
Didn't even realiz dam- is considered a cuss word...Why is America so censored and uptight, unlike Europe? It has always puzzled me... but that's another thread.. dont wanna jack this one
So to put it back on course... glass for tanks up to 180, and then I'd strongly start lookin into acrylic. That's just my opinion, I suppose glass tanks in the 200s are also ok.. I just know what a pain my 180 was to move around, and eventhough you only move it once or twice in your life, for larger tanks I'd have to say acrylic is much safer.
Just remember if you get
starphire glass, it will scratch, and will scratch pretty easily at that. I already have a little nick on my new 180, and I dont even remember putting a rock anywhere near it.
