Corals

[Redandluvenit]

I have some corals for some reason they are closing up and disappearing... Any idea why? I've lost my war coral and my green hammer

Any pictures? What are your parameters?

Unfortunately there can be countless causes. Best way to possibly get some help is list all your water parameters, age of tank, how long you have had the coral, and basically as much relevant info as you can

Salinity is 1.026. calcium is 460. Don't know the alkalinity. Everything else is good

The tank is a year old. I've had the corals about 6 months. Oh and the phosphate is about .10

The alkalinity may very well be where the issue is, you really should be testing for it if you are keeping stony corals. Aside from alkalinity, what are the rest of your parameters? Saying that ‘they’re good’ doesn’t really tell us anything, and even if you don’t see any issues with your parameters, another pair of eyes may see something you didn’t. It’s also helpful if you can tell us your parameters over the last couple months, as a lot of the time you can have parameters that are within range but if they are inconsistent or unstable you can have problems, so knowing what your parameters have been over time would be helpful (if you don’t keep a log of all test results, maintenance, dosing, basically anything you do or any changes to the tank, you really should start, whether a notebook or a spreadsheet, having that information is very helpful). Also, the size, age, and inhabitants (including CuC) of your tank and whether you started it with live rock or dry rock. Are you using RODI water and are you making your own saltwater? To help you troubleshoot we need as much specific information as possible

Also, if you’re keeping corals, you need to be testing Alkalinity, Calcium, Magnesium, phosphates, nitrates, and PH, they are all essential. It’s impossible to troubleshoot without knowing the quality of your water.
