[quote="Someone said something about being able to totally start a cycle and a new tank using all dry rock but it just takes longer said:
You'll have to add appropriate bacteria and a source of food for anything to "cycle". The smaller the food/bacteria input the smaller the cycle will be and the more likely you'll go through a secondary cycle when you start stocking your tank which makes the whole process just take longer. I really don't see an advantage to artificial cycles. Use a hardy fish and feed it. Maybe I'm just old school. [smilie=lol.gif]
Live rock cycles are really the best, IME. They get you there faster and the result seems to be better in regard to aspects of water quality that we don't really understand much less measure--aka, the mature tank phenomenon. As far as pests--yeah, I can relate, but I think it's generally well worth the risk. Sort of like driving a car in our society. Whichever way you go, a totally clean tank isn't going to happen. It's incredibly easy to infect your tank with any addition you make no mater how careful you are. It's just the nature of the beast.
"live sand" as you see on bag labels in an LFS means "probably has some bacteria on it"--maybe even a species that will survive in saltwater. Maybe not. I wouldn't count on it to do anything biologically significant, but it might."]

This is generally the best advice and I am a follower of this belief however I'm not truely "old school". The best approach in my opinion is to get some great dry rock(such as marcorock's etc) and seed it with actual live rock along with Dr. Tim's nitrifying bacteria with a deli shrimp also thrown in there. Using a true nitrifying bacteria product is not about trying to speed up nature, it's about creating the best possible foundation for your new tank. Totally understand about not bringing pest into the tank and that is admirable but..... unless you QT, dip or pretreat every single fish, coral, frag and grain of sand that will ever go into your tank, then it's a big unnecessary waste of time. I dip every single thing with 2 or more product's before it get's into my tank and I have still brought pest in, it's just the nature of the beast. Here's a good read by Dr. Tim, althought he does sell a product, every word he say's is pretty much dead on. http://www.drtimsaquatics.com/nitrifying-bacteria-mixtures-work-provided
