So, I am getting ready to do my first water change. I am using RO/DI water (I have my own RO/DI unit). I am doing about a 10% change of my 90 gal tank. I added the correct amount of salt to the water (I am using Coraline Marine Salt Mix). I stirred it for a bit, then let it sit for a while for the mix to dissolve. Oh, I also have a heater in the water. I followed the instructions on how much of the mix to add, the same way I did it when I filled my tank. I tested the water for salinity and it is way low. The only thing I can think of is that I have nothing aerating the water. Does that sound right?
Thanks
