Okay, so I have a 90 gallon reef and things seem to be doing well in this tank except for a couple of strange occurrences. I have in this tank what I thought to be a Xenia, however it does not have a "main stalk" all arms come up from an encrusting base on the rock that would be Anthellia correct? Anyway this coral was pumped up larger than life and doing wonderful until one day it started "dripping" to the rock below where new colonies seemed to attach and grow. Not a bad thing right? Since then the coral has not pumped back up, it lays sagging from its base "deflated" and obviously unhappy. I have a Xenia just 6 inches away on another rock that is growing rapidly and splitting into more colonies. On another strange happening in the tank recently (in the last 2 days) my large branching torch coral seems to be loosing one of its heads! The polyp won't open fully and seems deflated, all other 5 polyps are fully open and "pumped up". I did check my water and the results are as follows:
PH - 8.4 during the day
dkh - 12.5
Calcium - 450
Ammonia - 0
Nitrite - 0
Nitrate - <10
Phosphate - .6 (I put a phosphate sponge in over night to lower it)
Temperature stays between 75 - 77 degrees ferenheight
The lighting on the tank consists of two 250 watt 14k metal halides (hammilton) two 96 watt actinic power compacts (both on timers for dawn to dusk) and 4 watts of white lunar light.
All filtration is running perfect, and no animals to my knowlege are bothering these corals, the tank is running fallow with just inverts.
Any advice on this situation would be greatly appreciated.
Thank you!
