Hi I recently got a powder blue tang and it went straight into my display. Within the first 4 days I noticed ich / velvet on it. I’ve moved it to a qt treated with copper power. My question is could I feed nori in the qt tank? Could I leave the nori on the magnetic clip all day? Would it impact the ammonia levels in the qt causing it to spike? It’s a 20G QT with a small powder blue and a small hippo tang
