I recall the night perfectly. It was 3:00 AM. I was staring at a custom 120-gallon rimless tank Id just finished filling. Suddenly, I heard a sound. Not a crack, but a low, groaning "oomph" from the glass. I realized the tummy pane was bowing. Seriously, it looked as soon as a literal magnifying glass. I spent the adjacent four hours siphoning water into buckets, crying internally. Why did this happen? Because I followed a sketchy, antiquated aquarium glass thickness chart I found on a forum from 2004. before that traumatic night, Ive become obsessed following finding the truth. If you are building a DIY aquarium, you infatuation to know which tools actually guard your floors and which ones are just rolling the dice. This is My review Of The summit aquarium glass calculator Glass Calculators: Which Is Safest? and trust me, the answer isnt as easy as clicking a button.

Lets be real for a second. Most forgive tools online are frighteningly basic. They question for length, width, and height. Then, they spit out a number. But here is the kicker: they rarely accustom the safety factor they are using. In the glass world, a safety factor of 2.0 is the bare minimum. Its the "I hope my cat doesn't jump upon the tank" level of safety. For my peace of mind, I desire a 3.8 or even a 4.0.
