Really? That is kind of a bummer, that was the second biggest cost to my tank at $30 for 40lbs(1st was a Ranco Temp controller). I only used probably 20lbs of it. I have had sand before in my Saltwater Tanks and hated it. Others I know use CC and I know the risk of letting it sit without giving it a vac every once and a while. Well thanks again everyone for the help. Tonight I am going to get some gravel from my friends 55g undergravel filter to get the cycle really cycled. He said he hasn't cleaned it in about 2 years, lol...
