I was wondering how long do people leave nori in their tank before removing it? Is there anything special that people do to their nori before placing it into the tank? The piece I placed into my qt for my chromis I cut into strips on one end and than put it into the clip. They checked it out a little bit but otherwise have left it alone. About ready to remove it since they are settling down for the night, but was wanting to know how long I could leave it in during the day without risking it fouling up the water?
