I'm Moving and need to move my tank

[LeeR]

lots of waste from fish and what not settles into the sand bed and if you mix it up it releases into your water.

so if you can drain pretty much all the water except for a few mm over the send bed and then put the water back in without mixing the send bed up then you will be fine.

p.s. i would keep the rock in water for the move as too ensure you do not have any die off and do not have to re-cycle.
