ok this is a biggie,,, make sure you add saltwater to the live sand,, i screwed up and added freshwater (hey the ***** guy said add water, didnt say what kind) freshwater shocks and pretty much kills the sand...big ass no no!!!!! its expensive, and i wasted $80.oo on 2 bags and then killed it,, i emptied my tank,left in the sand , i added saltwater, but it was too late now my water is toxic!! and i have fish in it,,,not good.....death has begun... <img src="graemlins//yell.gif" border="0" alt="[yell]" />
