The problem is that it's the same tank and not a new one that is being moved. To try to take down, move and re-set up a tank and all the livestock is very tricky and stressful. If you can get your livestock out before and in a safe place while doing this it will make is much easier.NateHanson said:Is the problem perhaps that these tanks are moved too quickly, in an attempt to minimize the stress on fish and corals? I wonder if a week-long approach, where animals are moved gradually into a well-cycled new tank a handful per day, would be safer. I have a keen interest in figuring this out soon.
