So whatever killed the frogspawn is slowly killing the hammer coral. Everything else seems fine, and fish are happy, but I will have to figure something else out before I add another euphylia. I just put in an intake chamber 1 basket, floss, then my small bag of bio media that came with the tank, and bag of carbon in the second shelf, and my bag full of bio tubes went into the third camber. I was toying with the idea of leaving the foam in the second chamber since it is now empty and there should be lots of good bacteria in it. Any suggestions?
