so ive decided to buy regular sand instead of livesand, and clean it good.
then im going to remove half of my origanal live sand and put in the new sand.. i was told to do this and to let my old rocks colonize my new ones... so how long should i let the half of old sand "colonize" my new ones before i remove the last of the old sand and put in the rest of the new sand?


thanks,jesse
