I want to grow coraline on a bunch of dry reef rocks in tubs before using them to start a new tank. Because some of the rocks will be used with dwarf seahorses, I would like to prevent the growth of aiptasia and microhydroids. The coraline rocks that I am planning on using to seed the new rock occasionaly have an aiptasia and always have plenty of hydroids. So I was considering dosing the growout tanks with copper to wipe out any inverts when I first add the seed rock but I wanted to make sure it would be OK with the coraline. After a week or so I would remove the copper and allow the rock to grow until it was ready to add. Anyone have any experience with this or better ideas?
