For all of you that want my GSP's, I've tried to say that I can NOT get them off my rock. And that what I have left, is on big rocks that have other corals firmly attached. So, I cannot remove that rock from the tank, even to Lugols dip it, because it has the other corals and anemones attached. (Sounds like that would have been a good idea if there had been nothing else to worry about!) I would be happy to sell them if I could remove them, but I can't. (Otherwise they would have already been taken to the LFS along with the ones I did get off, which was about 5% of what I've got!!) So, all I can do is try and find a way to stop their growth. Can I ask someone to please explain how you apply the kalk paste, and won't that affect any other corals, etc?? Also won't it make the calcium content too high in the water also? I have a calcium reactor so my calcium levels are where they should be now. The area I would be covering with the paste would be feet long, so that would be a LOT of paste. Please someone tell me how this is done and if it is SAFE. Thanks so much!
