Hello, I just got a 90 gallon aquarium and I am going to add water in the morning. The guy is filling the tank at 9am but I work super late and don't think I can wake up to add the sand and rock prior to his arrival. Can I add the sand and rock to an empty tank and leave it over night? Or will the bacteria die that quickly in the sand?
