Ok, I have been recently reading some articals and books on setting up a reef tank. I broke mine down last year due to poor water quality in my area. Since I moved, I got the bug again. But there are 2 fields of thought. But before I jump into them, is this for an established tank or a new one.
1. is to place the rock into the tank if it is a new tank and let the rock cure that way. Run the lights and constantly keep an eye on your skimmer. This is to help promote any alage growth in the tank and let the struggling organisms thrive. The reason I was told to let the lights run is to help what is surviving live. I did this method when I first started my tank many years ago, it thrived for many years and my rock was incredible looking.
2. The other is to let it cure in a darken bucket, with a skimmer and power head and wait a few weeks.
So if you have an established tank, i would probably place it in another spare tank with lights or a lg plastic storage container again with lights, a skimmer and power head until the rock is cured.
