Hi I'm Jessica and I am new to this site as well as a new SW tank owner!! We got a jump start on this because we were gifted a tank that has already been invested in, with time and $$. We have a 75 gallon tank with rock, coral, flowers, sea anemone, starfish, clown fish, tangs, shrimp and a couple other things too. I need to figure out how to lower my salinity it's at 1.038 and also my blue starfish is sadly dying I believe. I need help!!!
