I bought 200# of playsand to set up my 150 gallon tank do I need to wash it or do anything to it before placing it in the tank of course I will be cycling the tank before adding anything my understanding is the best way for cycling is put the sand in add water and salt start the filter system up and place a couple of dead shrimp in the tank and let them decompose let the Amonia go up and then when it drops back to normal I can add some live rock and a couple of fish does this sound correct?
