We do not try to start cycles. The more dead stuff in uncured live rock the more toxins will build up killing more stuff.
The quicker you get the toxins out of the water the better. A protein skimmer will certainly help this process.
If there is no dead stuff, for instance rock is moved from one tank to another no cycling will take place. We do not need to cycle a tank if the rock is fully cured. a short bedding- in period will benefit the system however. Mini cycles and adjustments will take place to reach equilibrium in the tank. Also a period to allow criturs to build up a population is great before introducing predatory fish.
