polyps not out on 2 monti frags?

[kitenski]

I added 2 monti frags yesterday to my tank, last night they looked great, all polyps out. Today it looks like the polyps are all shrunk back inside the skeleton on both of them.

Should I worry, or are they just settling in?

Tank params are:

temp 25-26
ph 7.9 to 8.2
dkh 9.9
ammonia: 0
nitrite: 0
nitrate: 2.5
calcium: 400
Mag: 1410

Tank is a new setup, but using 18 month old rock and some water from my previous tank.

cheers,

Greg

Probably adjusting to the lighting difference.

Yeah, see how they go... if no difference in a couple of days, you may be a victim of the montipora munching nudibranchs. I had this problem, not very cool. They wiped out all the monti's in my friends 500litre system.

give it time wait for another few days and i am sure they will adjust ok. Your params look good , calc could do with being a bit higher to balance with alk but not out enough to cause much of a prob.
