The other day I noticed my ORP levels had jumped up 30 points, which is kind of unusual, so I began investigating. The only thing that I could find was that my Orange Guttatus Birdsnest Coral (Seriatopora guttatus) frag was turning white. My tank levels tested normal so I took the coral out of the tank. It’s a bummer to lose a coral but I would rather get it out before it caused further problems.
Some new pictures from this morning :
