Are any of these close to or touching the brain?
Chemistry is about 20 ppm nitrates, 450/460 Ca, 14 kH, 8.3/8.4 pH, SG was a bit high at 1.029. Lowered now to 1.026
The nitrates are a bit of a concern. You need to get those down below 10 ppm
on a consitant basis. The chemistry is kinda high as well. You really should let that fall to a more NSW
level. Elevating the chem above NSW
serves no purpose and can actually do more harm than good. If you are using a swing arm hydrometer to measure your SG
, I'd also let that fall towards 1.024. The hydrometer will most likely be reding innacruartely overall. Ph is good though..
I did notice that my 6-line pecked at it a bit but I though that was after it died. Dunno. Nitrates were at 15 and have floated up to 20+. Not sure why
The sixline could be picking at parasitic hitchikers. You might want to gentley pick up the coral (wear gloves) and inspect it underwater. If recesion or necsrosis have set in, you really need to get those nitrates down. They will only make matters worse. Water changes will be needed on a more frequent basis in the meantime.
You did not mention the water flow the coral is in nor the placement within the tank. More often than not these kinds of issues are caused from direct/sustained flow on the coral, an irritant or coral warfare. Feeding will help it recover once the source of the problem is found and eliminated but it will not alleviate the problem.
