As for the little pods that may or may not be killing your button polyps. I would try to siphon them out if possible. You may want to consider some kind of treatment for the coral too like a dip, but I am not sure what would be appropriate. There are many kinds of pods in this world and while most are harmless some aren't. I would try to eliminate the ones found on the button polyps. If they are harmful then they need to go. If it turns out that they are harmless, then you will have plenty more in your tank so no biggie on killing a few.
