kirsten that is a beautiful coral. I have seen this in my tank on a tenuis once a time ago and it was right when it first started showing growth as a new addition. this was way before I thought about any of the products we are discussing here. I did not have high nor low nutrients as we are now trying to achieve . my tank was average I think but no detectable nitrates or phosphates. it never hurt the coral it grew a funky lumpy tip on a couple only and then started growing normal. it almost appears as if the tissue is growing faster than it can make a skeleton. how high is your calcium? if it's below 450 maybe raising it slowly will help? I know they say calcium above 420 doesn't seem to speed up growth but it appears to myself and some others that it does in fact seem to speed up growth. maybe it doesn't but it sure seems that way. just a thought.
A cautious BINGO!!!
I have had trouble maintaining calcium and have had several drops below 400 in the past 2 months.
I have read on the SPS forum of similar tissue appearance when millies are in a growth spurt and some of mine look like what I saw over there.
I had never read about skeleton not being able to keep up but it certainly makes sense with my lower calcium levels. This would also explain the balloon effect of the polyp as it is emerging from fleasy tissue with not much skeleton to hold on to, or something like that.
ZEO boards recommend calcium to not drop below 410.
Other Acros in my tank, not growing, are not showing these signs.
If ya read my time line these symptoms appeared before I think a probiotic method could make a difference (but ya never know) I noticed before 4/17 as I posted a thread in the SPS forum asking for pics of tissue thinning thinking that may be what I was seeing and I mull things over quite a bit before posting for info.
I am going to drop my dosing to half, to be cautious, keep my calcium at 430-440 and move onward.
Ceretta..........Please note I never said I felt what I was seeing was a "bad thing" just something I have never seen or read about before.
As always...........time will tell.
However, as far as my LPS and Zoas, the addtional stripping of the nutrients in my tank, making my 400W lights extremely intense for them, I believe has caused their problems.
THANKS ROBERT!
