Understand also that as wonderful as this rock is to work with, as well as to look at, it comes in LOADED with bound up phosphates. Curing is not the same thing as cycling and this rock should really be cured before introducing it into your display tank. Unfortunately, this can take quite some time. Failure to do so however, could result in an algae spike so fierce that you'll be battling it whole lot longer. As an alternative, you might try Marco Rock. I don't have any first hand knowledge here but I've heard it comes in with far less PO4 and can usually be placed directly into the DT, particularly in smaller amounts.
