I've been pretty busy with work and not posted in a while. Aside from breaking my ankle pretty bad I suffered some setbacks in my reef. I suspect that had a lot to do with the addition of the kalk reactor though I cannot put my finger on the exact cause (possibly a combination of factors). In any case the tank is on the rebound now and survivors that took a hit are recovering.
It started with all my monti's including caps. digi, setosa etc. with a varied speed of demise STN-RTN. A lot of that I had gotten for free and was getting ready to give away so no huge loss. The only pieces I had paid for and was planning on keeping were forest fire digi, peach digi, setosa and a sunset monti. All gone and the only piece replaced has been a orange digi frag to test the waters. It wasn't isolated to the colonies either. I had frags of a lot of that stuff and they perished also.
Interesting enough it only affected a few frags (mostly frags of my existing stuff). The stuff I had gotten from Battlecorals was unaffected although the PC Rainbow didn't make it probably for other reasons. The painful part was the loss of some larger growouts I had. I lost a pink birdnest, bird of paradise, a high end blue/pink/green stylo, red dragon and a few older nondescript frags. My softball sized UC wild orchid had the top stn off. I clipped the bush off but all the heavy encrusting survived un-phased and has colored up and is growing rapidly. Unlike some others a frag of that I had also survived.
Of course none of the Ricordia, zoanthids or other softies were affected. My first sps in this tank was a red planet and its still cruising along with some others like strawberry shortcake. For the most part purple nana, plum crazy, garf bonsai valida, ice fire echinata, bali shortcake, pocillipora, blue tip stag and one millipora were unaffected. I only have one LPS brain these days and its also fine.
The best I can say is live and learn or like they say **** happens. Tank thriving for about 1.5 years and then smack.
