Hey guys, I'm having issues with my Vertex Omega Skimmer. I recently transferred a blue hippo tang from my wife's tank into mine. During the process the tang must have rubbed pretty hard on a rock because we noticed a scratch on its skin. My wife dosed API Stress Coat to help it heal and she also dosed some garlic to help with stress. Anyways, my skimmer started going crazy so I had to turn it off. I had it off for a couple days, so I went to turn it back on last night and it's still going crazy. How can I fix it and how do I prevent this from happening again? Will my skimmer do this once I start dosing Alk, Ca, and Mg?
TIA
