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?
Plenty of light, 3x150 hqi medium to high in the tank. Lots of flow, too much more likely than not enough. They like quite a bit right?
I've found that they like lower flow and lots of light. I've also had new frags just melt away on me for seemingly no reason
Well... I just installed a ca reactor myself... and my alk has been 11ish (still tweaking, *sigh*) ... and my pompom xenia is having a tougher time too now. I'm thinking either it didn't like the swing, or it prefers low alk. :-/
It was poopy when alk was 7... Have also tried less flow
Xenia can die for no reason IME, grows like gangbusters then dies.
IIRC, in its natural environment large masses die when there's a temperature spike, in most cases I've experienced that has not been the case though.
Temp was an issue a couple months back. Chiller installed since. They really haven't recovered though...
low nutrients?
So low nutrients is a problem for them? Huh, that could
be it...what they like some of? Nitrates or phosphates? Should I be trying to fees them somehow? Didn't think they really ate...
Have you looked into dosing iodine in the tank? I started dosing iodine in my nano that had xenia and the stuff TOOK off.
Are they getting enough light?
