Sand Substrate

[Antwan]

So with your method Lightning, could you put the sand in the tank with the fish or do I have to leave it empty till the sand settles?

are you going back with all new water or with your allready established water?,, if new,, ya know ya have to let that stuff cycle, i saved 30 gallons of my old water and left my fileter media in there when i changed mine out, i put my fish back in there within about 3 hours of origianly taking them out, i had the gravel allready washed and everything ready to go,
