lookin to cycle live sand for an established tank....

[jkcrumb]

I currently have a 125g w/ 150lbs of live rock and some live sand.......I am looking to build up my sand bed to about 4" so I need to add some more sand..........question: Can the new live sand be added directly to the tank (maybe in 5lb increments) or do I need to cycle it??? If I need to cycle it any ideas on how to do so???

If the sand is actually LS then there wont be a need to cycle it. Yes, I would add the sand in increments. You dont want to stir the sand bed up too much if you have livestock in it.
By the way, even if the sand was not LS all ready you wouldnt have to cycle it. It would become LS eventually. If adding sand that is not LS then you would want to go through an additional step of rinsing the sand out in saltwater. So just put the sand in a bucket, pour salterwater in. Then take out the extra floating particles.
If the sand is LS then you wouldnt want to take anything out of it.
