[davosmarine]

Hi new here I have a war coral and it seems to getting lighter at the bottom and am worried that it's starting to die .my temps are 24.5 salinity 34.4 but mu pen battery was dieing and gave me wrong reading now as sorted that and got it bk to the right area not sure on the rest as a don't chase numbers

Temp and salinity are fine. I would recommend testing for alkalinity in any tank with stony corals in it.

The coral mostly looks okay. How long have you had it?
Tank looks pretty new?
What is your specific lighting?

These corals are very forgiving, and I suspect a slight change with salinity may have been the culprit. Assure there is no significant change with alk and CA

The tank is 6 months old now a just had a test done today a know my cal and mag are low and my nitrate and phosphate are high can this be the issue thanks

Calcium of 531 ppm is actually high, but shouldn't be a problem at that level.
Mg isn't low. It's fine at 1263 ppm.
Nitrate at 37 is high bot not lethal. Just make sure you are doing water changes.
Phosphate at 0.6 is pretty darn high. Likely from the new rock. I would slowly work on that.

Alkalinity at 103 ppm might be your problem, if there is a problem. That's about 5.77 dKH, which is really low. I would get a liquid test kit for alk, and start monitoring and dosing for that manually. Shoot for 7-10 dKH or so, or 125+ppm.
