For anyone to be able to help you we will need more information.

Size of tank, what set up are you running, sump or sumpless, protein skimmer, what other equipment are you using, how long has the tank been set up. Are the corals and fish the only recent additions, what other corals you have especially in the vacinity of the one that died. Has anything else died in the tank recently.

Do you add any supplements

Need the exact figures for the tests you mentioned.

What sg are you running at and is this measured with hydrometer or refractor. What salt do you use.

What is the name of the coral that died, latin preferably.

hi

many thanks for the reply

I'll carry the tests out again ... I did take a water sample to our local aquatic shop where I buy all my bits for him to test the water .. and he said the water was spot on ..

its a aqua one 900 with marisys 240 ..

the only coral close is a leather ...

the tank set up was started in january 2009 .. I use Nutrafin / reef carbonate .. I use sera premium sea salt ..
I use both a refractometer and a comfort - hydrometer

refractometer shows 1.024

hydrometer shows 1.023

trying to find the name of the coral ..

I'll get back to you asap

cheers

Sorry you are having trouble. Yes, Tina is right---the more information the better... what size is the tank?

It's difficult to say with authority why your coral expired. The best we can usually expect is an educated guess.
When I see a tank where most corals are doing well, but a few are not, my first thought is possible aggression issues or chemical wars. This is often a major issue and many hobbyists have no idea how aggressive these animals can be. Leather corals are known to send out sweeper tentacles and also release noxious terpinoid chemicals into the water, (similar to turpentine) which must be regularly removed/reduced with carbon and water changes. Hammers, Elegance, and Bubbles can all be very aggressive. Galaxea Corals are known to have stinging sweeper tentacles that are almost 12 inches long! (it's a jungle in there) More details here:
