Hi everyone, i got 1 torch coral with two(2) heads almost one month.But today, only one head is expand and another one not so much. I just made my waterchange last week on sunday. Unfortunately i got no any test kit yet, only the refractometer. My salinity was 1.025. By the way, some of my other coral such as hammer, bubble, mushroom, birdnest and gsp are doing great.Hope you guys can help me up. Thank you
