I'm kind of in a hurry to get out the door, so I'll have to fill in some details later. I've had this bubble coral about 3 months. Here's what he looked like about a week after I got him:
Here is is tonight:
Lights are 150W metal halide (unsure of color temperature) + 28W Actinic VHO
. He's about halfway up the tank (approximately 12" from lights)
pH = 8.0
Ammonia = 0
Nitrite = 0
Nitrate = 5
Phosphate = 0
Calcium = 460
Temp = 80
I think the problem started with too much flow on him, and I redid a lot of rockwork last weekend to deflect that.
Fish include the fire clown, royal gramma, Carpenter's wrasse, Kaudern's cardinal. The only mobile invertebrate is a coral banded shrimp. No other corals are close to him.
Any ideas or thoughts to help him out are appreciated.
