So, my rubbermaid storage container I had been using for the last few years decided to pop a seam while I was in the process of hauling water upstairs for a water change. Several towels and a very upset wife later the mess was all clenaed up. Thankfully it happened while I was around and able to prevent all 20 gallons from spilling into the living room. Obviously I dont want to have this problem again. I'm thinking about getting one of the Rubbermaid 'Brute' Garbage cans. For those of you with large tanks (and large water changes) what do you use for mixing saltwater?
