Cool.. Thanks for the input.
As when I put mine in, the tank was only more than a month old. But it's doing fine now. At first, a large part of it was died off (shown only the white skeleton bare bone) but now, I can see it started "violation" to the base rock that it was glued on. Fast but faster still my worry.
As you mentioned, it like the dirty water, which meant, my water is prety much ... not very "good" to other things but him.
Do you want to trade some pic of yours and mine? see how different? - I found not many people having this kinda coral in their tank
But since we have, we will follow it 'til the end.
Thanks,
