Due to my own neglect, my frog spawn coral is doing poorly. It use to be so beautifful. It was not till the other day that I noticed there was little air flow. The filter was clogged. I don't know how long it had been that way. Everything else in the tank is quite healthy. I guess the frog spawn was more sensitive than the others. It is not completely dead. Is there a way I can bring it back to its former glory ?
