Adding liverock

[orthoboy]

I currently have a 100g fish only tank with a purple tang, nasotang, hippo tang, and 3 damsils. The tank also has a protein skimmer. I am about to add live rock to the tank, but I was told I would need to add it slowly. Any advice of how much to add as well as how to add it? Any help would be apprecitated

I am not sure exactly how much to add at a time, but i know to add it slowly and test the water as you go along. adding to much at a time will probably kill the fish you have in the tank.

I have been contemplating add more live rock to my tank to and this is what I came up with.
Since I have a 29 gallon tank as my q-t tank as a spare tank, I was planning on buying about 50lbs of live rock and placing it in there to re-cure for a few weeks. Once it is cured, I believe I can add as much as I want to my 80 gallon tank without my harm. The key here is that the rock is not out of the water for more than a few seconds. Cured rock, IMO, is safe to add (assuming you cured it at home).
On the other side, if you buy cured rock from a lfs, you need to take it slowly as there might be some die off from taking it out of the lfs tanks and transporting it home. I have done this before, and I experienced a small mini-cycle in my tank. I didn't have much live rock to begin with so that my have affected my tank. Now that I have 60+lbs of live rock, I think I could add 5-10lbs of rock and it should be ok. Just go slow if you go this way and make sure you test.
Hope this helps!
