How long do you guys wait to turn on your skimmer after you dose stront, iodine, calc and trace? 24 hours? Also,I bought a button polyp colony last weekend and it looks like its starting to open but its definately not as nice looking as it was at the LFS. I tested my water and my KH is at 13. how do I lower it? I have a lime green trumpet thats doing excellent, but I also have a hammerhead thats not as big as it was in the store either. Kinda getting frustrated.
