On the plus side of things for the 180, I got the nitrates under control and the cyanobacteria has disappeared and it appears that my sand bed has come back to life. I've had no deaths of any Coral or fish other than my Fairy Wrasse that jumped out of the 45. I also discovered a bird's nest growing that I thought I lost and some pocillopora beginning to grow on a rock. To me that is a good sign yet the tank is suffering at the same time. I've got either hair algae or bryopsis. And I'm going to treat that was some fluconazole when I get back. I had hoped to be able to dose it before I left and then do the clean up and water changes when I got back but it's not going to arrive in time. With any luck I might get my daughter to treat it when it arrives. I'm very torn about what to do about the aptasia though. If I put peppermint shrimp in there I would have to put quite a lot and I think my rasses would kill them off pretty quickly. My other thought is if I purchase a couple hundred dollars worth of berghia nudibranches I might be in the same boat as the peppermint shrimp. I wish I could catch those two Devil's in my tank! It would make my life a bit easier LOL
