Does copper kill coraline?

[olinf]

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?

Do not use copper.

Copper can stay with the rocks.

Why not use the rock in the tank and get rid of the aiptasia as necessary?

I agree with above. The copper could stay in the rocks and then leach out into the new tank with the sea horses. not sure, but I would think that copper would be deadly to sea horses

Thanks all, back to the drawing board. I had my doubts myself, I know my LFS keeps their LR in copper, but thats a LFS so I thought I would check it out before I tried it. The aiptasia is of minimal concern, it can be dealt with. Mainly I want to prevent the small hydroid colonies that can explode in dwarf seahorse tanks and harm the young. I know the hydroids are sensitive to FW dips so maybe I will just give the rocks destined for the dwarf tanks a dip before adding them. Unless I can come up with another brilliant idea.

Thanks again, Olin

Your LFS keeps their live rock in copper? My my, that must be some beautiful rock...

Yep, just one of many reasons I am growing my own!
