Coral reefer
Past President
In a mixed reef everything is doing well except for the xenia. Any ideas? I think ph is really important for them, they are shrunken and definitely not pulsing anymore. Temp is constant 77-79, ca is 440, all used to be low, like 7, now it is up to 11-12 over a few weeks. Po4 is really low, running gfo. Haven't tested mg but all else is good and I'm up on water changes with seachem reef crystals. Ph looks to be 8.2-8.3... Any ideas?
