Good luck with the cyano. I used some red slime remover, but I understand that if the tank is less than a year old it can kill everything.
I'm currently dosing the AP Algae Fix Marine for my hair algae problem. From what I've read, it usually starts to kick in around the fifth dose. I recently did a two-day blackout, which helped with the algae somewhat. I'm hoping it weakened it enough for the Algae Fix to work. My corals and fish were all fine without light for two days.
Sometimes, odd things show up in your tank. It's possible a hermit pulled the shell out from within the rock, or something.
