Okay all you fanatics lets see if you can shed some light on this for me. I have a 24g Nano that has been going for about 18 months. It is stuffed full of Zoas and Palys and has always been beautiful. Over the past few weeks I have some clusters that are not opening. Everything is the same but they seem irritated. I asked around at LFS and they have me testing Calc and Iodine with Salifert, no real clues there.
Any idea what is going on???
