I have a nice Duncan piece that has 8 adult heads and about 12 baby heads. This coral is always expanded and has been growing like a weed ever since I've got my water dialed in. The adult heads are about 1.5" in diameter not counting the tentacles so I noticed right away when they all were closed up. The adults are about 85% closed and the babies are about 95% closed. They been closed up for about 2 days and now I'm getting a bit concerned. I noticed a little bit of that slime stuff today that corals give off when they're really pissed.
I've tested the water:
7 ( I know thats a bit low but that's where my alk
always is and it's been fine along with evrything else.
The only thing that I did change that I'm thinking could have cause this is I changed out both units of my chemi-pure elite a couple days ago. Looking back, I guess I should have changed 1, waited 2 weeks and then changed the other, but I didnt.
Questions are: do you think it's the chemi pure? If so, u think the Duncan will pull thru?
I'm going to do a water change tomorrow and hopefully that will help him.
Thanks in advance.
