Okay if you want to get into semantics, "hit" is a better word. But this whole thread is based on "what if". Manufacturers put tempered glass on the bottom of tanks because it wont be HIT there. Its really just a case of if the tank does get whacked hard enough to break, do you want time to come up with a plan or do you just want the tank to give out. Ideally, you wont ever hit it but in the end tempered glass does give a darker green hue.one little tap? to break tempered glass?? I guess you've never actually tried that. to each their own i guess because if you hit untempered glass as hard as you did to break the tempered glass you'd have lots of big razor sharp shards coming at you. most if not all your tanks bottoms are tempered and they don't spontaneously break.
I very much agree with this though, ultimately acrylic is the safest bet. It's 10x stronger than glass and is pretty much shatter proof. Not to mention it gives the best possible clarity. It does get scratched easily but you can buy scratch resistant acrylic for your front panel AND theres something to be said for a material you can buff out and clean up to make look brand new even if it is scratched up. I bought a used beat up 325G tank that was all kinds of foggy, a couple hours of buffing and the front panel now looks like I just set the tank up and filled with water almost looks invisible. AND its so much easier to move, my 325G weighs about 175lbs. a 325G glass tank would weigh 4 or 5 times that much.maybe we should stop the use of glass and just go with acrylic?
There's a reason Aqueon tempers the bottom of their freshwater tanks.
PS. Unless you are heating your aquarium to 400 degrees, I wouldn't worry about the oven glass shattering thing.
If you want to keep the weight down, the no-brainer is use acrylic.
At the end of the day Acrylic is stronger, lighter, and more translucent. You trade off the fact that it scratches easier but it also buffs out easy. If youre not worried about price, go with acrylic.
The scratchiness of acrylic doesnt sound like a big problem at first, but gets very annoying over time.
Agreed, and unless I have missed a chapter over the years, the tank needs to be drained down to the level of the inside scratches, in order to be buffed out. Am I wrong here? Because that is most definitely a major PITA, when big tanks, and big fish are involved. I have a friend in town that has built some large acrylic tanks (300+ gallons) and the only large tanks currently in his fishroom are glass.
An errant piece of sand caught in my mag-float is my most recent headache on my acrylic. Scratches all over the inside of my tank. I realize it sounds like a stupid mistake to make, but trust me--incredibly easy to do!
