Ok, I set up my tank with live sand and cured live rock. Put some shrimp in there. After a week there was no ammonia spike. I added a few hermit crabs and a couple snails. Still nothing. I'm only at week 3 but all my levels look good. Is it possible that it didn't really show a cycle because the sand and cured rock? I would love to pus a fish in there but I allways thought it would take longer to cycle. oh yeah, 29 gallon tank, 20lbs sand, 27 lbs of rock, 500gph circ pump, HOB filter till I can afford a skimmer.
