In situations like this you need to go back to the basics and work from there. You had told us that everything checked out fine, but can you post all your parameters? Your most recent one. You said that 1.028 is your salinity reading. Though it is high, how did you get your readings? Hydrometer? Refractometer? Or a salinity monitor? Also, are you dosing? How long has the tank been setup? What kind of lights and filtration are you running? Maybe it isn't fully established yet. Please give us full details and we'll be able to determine from there.
