if you can report the situation in your thread including:
salinity
age of tank
size of tank
livestock
alkalinity
temperature..
l......if we have these things for starters we can be more help faster. If you don't have tests, today is a good day to get: a refractometer (salinity) and a numerically based alkalinity test (Salifert is such a test). Your salinity should ride between 1.024 and 1.026 unless you have a fish-only, which can be a shade (1.019) lower. And your alkalinity should be between 7.9 and 9. I prefer 8.3.
Tell us what your fish/corals have been through, eg acclimation, quarantine, dips (by brand name).
Tell us whether you're using ro/di.
Tell us anything you've added to your tank that isn't salt.
