I have a large basement sump that has approx 75 gallon fuge. I also have another 40 gal breeder that is plumbed into the system that I was going to use as a frag tank later that is now empty with sump water running through it. I was planning on adding more Live rock to the existing 60 pounds or so in the fuge and a bunch to the 40 breeder. I am probably going to get the rock from someone on CR that is breaking down their tank. I have a tub set up to put it in and examine for unwanted pests, but what else should I be worried about?, and can I add a bunch of rock to a system without a major problem with the tank chemistry? Any ideas would be appreciated, thanks.
