I know but how do I get it down? I asked here about it a while back and
the consensus seemed to be that it wouldn't hurt anything.

Hi all,

I bought a leather coral on the 6th December and it keeps opening and
closing a lot. Sometimes it is open for days and then closed for days and
at other times it is open during the day and closed at night. It has shed
a mucous type stuff a few times which sort of looks like when you peel
from sunburn. The corals that came on the live rock are all fine, in fact
they are spreading/growing well. Is this normal behaviour for a leather
coral?

I increased the water movement around it after it's 2nd week here which
made no difference and increased the metal hallide lighting by an hour a
day. It looks great when it opens.

My Calcium level is still at 600 and my tank is only a few months old. All
other tests are normal, Ammonia, Nitrites and nitrates 0, Phosphates 0, SG
1.023 and pH is 8.4. Temps here in Oz have been hotter than normal but
until a couple of days ago the tank never got over 29°c and then it just
touched on 30 for one day. The first few weeks I had it the temps were
around 26/27C. I really don't want to spend $1000 on a chiller.

I only have a young pair of ocellaris clowns, a pair of pyjama cardinals
and a coral beauty in a 700 litre tank along with a coral banded shrimp
and an unidentified crab.

Is there something I should be doing or is this normal behaviour (or
normal behaviour for a newly moved coral)?

Thanks for any advice.
