This is how I fold the nori. 1/2 sheet folded to 16 layers. Fold the loose end inward. I suspended the clip just under the surface of the water using a fishing line. Pull it out and reload daily. When the slip as some algae growing on it, I just let it dry out for 1 day, then it will be as good as new. These clips are so inexpensive (Ocean Nutrition) I got spares to trade out when the clip get dirty. Feeding nori this way is easy to load, hand does not touch the water and the Nori never get ripped off and float around the tank. Fish just always got bite size off the clip every time. Suspension prevent invert from crawling on to the clip and eat the nori.
