I was just about done filling a new 285 gal (52" x 36" x 36"). 3" from the top, the side exploded out. The force was strong enough to move the 240lb steel plate next to it.
Please, someone tell me again how this is a relaxing hobby.
It's 1/2" acrylic and I was standing right where half the water decided to go. Glad I was filling with warm water. But, it still got a little nipply running back to the house. I kept fronts in it at my last house. It must have sustained some damage during the move.
