I've got 50 lbs of base rock in my tank. It has been in for about a month and a half now and the coraline is starting to take hold. Kinda funny actually, my live rock is growing a small amount of hair and the base rock has none. I too found the base rock to be just as porus as live rock. I had one piece that was fairly solid except for a couple of 1 inch holes through it. It is a favorite of the percs to swim through. I made rock prior to this. I cured it for a bout a month, and the PH was still above my test kit. I also read some posts, that there may be other elements that leech from the conrete. I think it was on reefcentral, but can't remember. Knowing what I know now, I would just buy the base rock unless I was trying to fill a particluar area and need a specific shape. Hope this helps.
