These nets are so strong you can use them to scoop and lift wet gravel, plants, rocks and coral. The soft, seamless 1/16″ mesh is gentle to fish and molded into a rugged, 1/4″-thick ABS plastic frame that won’t bend or scratch the tank. 1/8″ stainless steel shaft is 3″ long. Nets can be boiled or bleached for sterilisation. The smallest one has a 2″ deep bag; the others are 3″ deep.
