I have chance to get a couple of large tanks (125G) but I am little gun shy to get them. You see I had a 300G tank I bought from a pet about a year ago and it bust on me. I am sure someone knows the rest of the story water all over the place, and a lot of costly repairs. I was just wondering if someone could give me some advice on testing the tanks or something that cold lower the chance of this happening to me again.
