This is tissue recession and due to stress. Hammers require stable tank conditions and is intolerant to major swings in water quality, and is sensitive to almost any level of copper in the water.Seems like my frogspawn coral Started to have an issue recently. A part of the skeleton exposed when the lights go off. My torch has retracted since few weeks. Even after dipping in coral Rx, no pests were found. My cleaner shrimp is nipping at the exposed area too.
My parameters are pretty much stable and as follows
kH - 7.4
Mg - 1500
Ca - 430
Po4- 0.1
No3- 2.5
PH- 8
Salinity- 1.025
Temp - 26
I didn’t dip the frogspawn as yet. Don’t know whether this is a pest issue or cos of water chemistry. I do a 20% water change once or twice a month. And feed corals 2-3 times a week with AB+ and reefroids. Can someone tell me what to check or do to overcome this? Thanks.
Calcium and alkalinity are two very important water parameters that will affect the growth of this coral which will start to die off if the calcium levels are too low. A calcium level of about 400 ppm is just right.
Euphyllia isn’t terribly picky when it comes to the proper placement in your tank and best is to avoid the extremes which are extremely bright locations and areas of very high current, as well as avoiding areas that are too dark or with currents that are too low. High currents risk damaging the soft, fleshy polyps (and getting an infection) and bright lights will cause bleaching. Insufficient lighting will cause the coral to wither away and starve to death.
Hammer corals require just a moderate amount of light for photosynthesis and will grow well in the middle regions of your tank. Just about any reef LED lighting should work for these guys. Placing them on the sand bed often will allow sand to irritate it.
The polyps should sway in the current, but not under so much flow that they are constantly bent over their skeleton. Too much flow will tear the polyps (worst case) and cause the polyps to not extend so, don’t give them too much flow.
