My Long Polyp Leather Toadstool seems to be “balding”, any ideas why? The front seems to be fine but the back has a lot of closed polyps. There is not extra flow towards the back or more light. I’m thinking it has to do something with Ammonia which I just added to the tank. Parameters: 8.0pH...

I had gotten 2 Zoas frags semi-recently. In the past 2 months (one a bit more recently). 5 Smallish polyps of Gold Dust Zoas (just basic gold and brownish). And some Mandarin Orange (about 7-8 polyps). I dipped them. They opened up quickly and looked good. My Red/Orange Oxides (not sure what...

Hey R2R! I purchased an awesome rainbow monti on 6/8 from my LFS, and have a question about how to get the best PE. The coral overall seems to be fine, and has great PE at night and doesn't seem to be bleaching/receding. It's still on the sand bed since I'm letting it acclimate. However, the...
