Here is a photo taken today, from my coworkers tank below. My coworker bought this sun coral from one of our LFS a few weeks ago, they had discounted it because it looked on its way out. There is only one polyp left now. His parameters aren't 100% (although I read that shouldn't matter that much for NPS). Even so, I have been trying to help him out with his parameters (since I already have calc, mag, sodium bicarbonate, etc) because his corals in general weren’t really growing in general, so I’ve been helping him dose various chemicals. Anyhow, in the meantime he has already given up on this coral. Beyond that he doesn’t have time/isn’t at work everyday to feed it every day. Since my parameters at my home tank are finally perfect, I thought about giving it a try to see if I could resuscitate it for him. I have the time (and the lack of life) to feed it every night too, if I were to try. It always had some hair algae but this week in his tank it developed a bunch of bubble algae all over it. My question is: *Is it worth introducing the bad algae to try and save it?* My tank at home doesn’t have any kind of problem algae (bubble or hair) and I actually have a little fuge with dragon tongue and tons of chaeto that does such a good job, I worried about not having enough food for my emerald crab (I constantly feed him the good algae). But is it worth contaminating my tank to try to bring this coral back to life? (Even though my emerald might consider it an awesome snack). What do you guys think?
