There's going to be absorption (from the rocks/sand), so you'll need to use the Hanna High Range Copper Colorimeter (HI702) and test daily. Redose copper as you see the level dropping. Personally, I'd go with Copper Power because it has a wider therapeutic range (1.5-2.0) than Cupramine (0.4-0.5). So, easier to stay within therapeutic despite the absorption. Like I said, daily testing is the key.

No matter what copper you use though, you are looking at months of running Cuprisorb/Poly filter to pull all the copper out of the tank to make it reef safe again.
