I understand fully now. Thanks for the help. Looks like ill be rising my sand out to make it nice and clean.Sorry, no.
If your removing the rock, water, to move the tank, just scoop out the sand. Rinse, use some tank water for final rinse.
The majority of the rinsing is out on the lawn with a hose and tap water. You can clean the tank if you want.
Your doing all the work anyway. The sand is the dirtiest part and doesn't make sense NOT to rinse it if your cleaning all the rest.
