thanks guys your a wealth of info! Sorry it took so long I had to do some cemistry!
The hitchhiker is probably an "Aptasia"...get rid of it...However, that is not the problem that you are having.
How long has the tank been up and running BEFORE you added any animals?
When did you get it?
How did you acclimate it?
If you've had your water tested and the coral has not been in there very long. It may be in shock. With the very little lighting that you have I would suggest that you put it near the top of the tank close to the lights. I'm running 3 Metal Halides at 400w each plus 4 T5's at 54w each.
Do you have good water movement? If not, go buy a surplus pump to put in the tank to get the water moving.
What are your water parameters??? I know you said they were good but, what are they? When did you have the water tested? If it's been awhile and you have not checked the water in awhile the parameters may be drastically off! Also, I do 10% water changes EVERY WEEK. Nothing is off in my tank because it doesn't go very long before being re supplemented.
What are you supplementing your water with in terms of Alkalinity and Calcium? These are the two most important chemicals. You must have some sort of Calcium Carbonate and some sort of Sodium Carbonate to keep the Calcium at about 425-450 and the dKH should be about 8-12. You may have to monitor these daily for awhile.
The tank was running about 5 weeks before any animals.
The coral was just dropped in with I guess some bad advice?
Got the coral about 2 months ago.
Great lighting set up you have there!
Reefaholic you live in Buda as well as I do maybe one day you can stop buy and give me some tips??!?!?! I'm sure ill be embarresed for the lack of knowledge but I promise I'll catch on fast!
The coral has been in there for about 2 months just noticed this about 2 days ago. The water movement comes from a single number 3 coraline propellor.
I have not used any supplements at all but here are the readings:
Calcium = 460
PH = 8.4
Alkalinity=300
KH= 19dkh
Phoshate=1.5
Nitrate=20
So what would you experts suggest? A water change? Aslo, the aptasia what the easiest safest way to get rid of them...I have a bunch! Anyone want any...hahaha lol
