I am about to move my 75 gallon freshwater tank and I have a few concerns. First off where the tank is going to be is on a second story, I am worried about the weight. There is the tank, a 20 gallon sump, and a 5 gallon bucket for the ATO reservoir. I did a rough estimate and it all weighs around 1100 pounds. Second, I am worried about keeping all my BB alive. I plan on bringing a minimum of 40 gallons of water (8 buckets). Is that enough water from the previous location to keep the BB from dying off with all the new water? I don't plan on getting all of that water the same time that I take the tank down, I'm going to bring the buckets in separate trips. Does it matter how long those buckets sit before I put them in my tank with my fish?
