Ok I have had live sand in for almost two weeks and live rock in for a week. I have twenty pounds of sand and 11 pounds of rock. I have been checking levels everyother day all is well or it has not even started yet. I was looking for my ammonia to rise but nothing. Got home Sunday an something has made these little tunnels in my sand bed. The lines are the size of a pencil line on paper have not seen anything moving in the tank. Do you think a should wait longer to introduce a clown or do I need to introduce the clown to help the process. Please let me know what I need to do in these situation. I am not in a hurry I just feel nothing is happening in my tank. I also have been adding seachem sability foe the past 7 days.
