I am currently in the process of filling a new 220 with RO water. My plan is to mix salt water in the new tank. There is some old sand and base rock in the 220 now. I am trying to figure out the best way to move everything over from the 120 to the 220. My big dilemma is how to move the sand form the 120 to the 220.
