Sometimes if we use a good amount of live rock and sand we defintalely can decrease out cycle time. We always experience a cylce of some scale. Bacteria, algae, etc. need time to build up on new equipment, glass etc. and this takes time even if live rock, live sand, and water is used from a well established previous system.
I have had pretty good luck with good live rock and sand in setting up entirely new systems. Most of the time I just have minor ph swings with littel other instability with the excetion of some amonia, nitrite, and then nitrate. Most of the time it is just a noticable increase in diatoms.
