Found my 125g leaking earlier. Drained the tank, netted the fish out. Managed to get it outside and get all the water off the floor. All the fish are in a 10 gallon. I’m planning to get another tank tomorrow. I thought this happened because this is a old, beat up tank I bought on CL, but I’m not 100% that’s the reason. It has a lot of scratches and chips but it held water for several months. Is there anything else that could have caused this that I need to know about before I setup another tank? I had 2 stacks of three cinder blocks on each end with two six foot 4 by 6s as the stand.
