So i accidentally cracked my tank

I hate to see this and I’m sorry that this happened with your tank. This is a healthy reminder to always check for tempered glass before drilling - the polarized sunglasses approach is easy, cheap, and effective.

It's OK. I swear I checked and the glasses turned black when I turned them 90deg. (thats the test right?) It was a spare 29G I had (used) was going to use it for remote refugium. probably for the better. It was a little long. The 20 high I picked up will probably work better.

What's the polarized glasses trick? I assume the glass looks different through the glasses if it's tempered?
