A Sad Day

While I was home over Thanksgiving break I added four cups of salt directly to the sump because the refractometer wasn't calibrated. The salinity in the tank was at 1.022 but all the corals looked great. I raised the salinity to 1.027 over the course of four hours. After I returned to school I received a call from my Dad that the Skittles Granulosa was losing tissue. This was the second time this happened to the coral. The Granulosa was the only coral affected by the salt increase and ended up completely dying. I never realized how big the coral was until I saw how many frags were made out of it. Here are some pics of the frags that were made to save the coral.
