Alright i am planning on moving in a couple of weeks. Now i have two tanks both about 30 gallons. One tank has about 50 lbs of sand and the other has about 20. The 60 lbs has a horshoe crab and a conch sand is very clean looking and always being mixed up. The other tank only has snails sand is dirty looking. Should i completly change out the sand for new sand or can i rinse it out good? Next question. Water should i reuse as much of the water as possible or all new water?
