Avoiding a sandbed crash when moving tanks

[Madreefer]

I too have done this several times. Just rinse ur old sand and keep rinsing. I use RO water but I have a huge reservoir. Keep 2-3 cups of your old sand and don't rinse that and just mix it in with the rinsed sand. Don't know about the others but I do the same with brand new sand anyways. But if one can afford to run a SW tank than sand really isnt that expensive
