Hydra-Nets are built to last! The Silt Net features an ultra fine mesh with strong, easy-dry rubber coated silicone, which is kind to your fishes’ delicate scales and fins. The net is 18.5 in. by 15.75 in. with deep net pockets up to 17.75 in. making it easier to maneuver fish into the net. The rubber coated silicone rim is safe to gently clean the bottom of your pond. All Hydra-Nets are fully compatible with both Hydra-Poles (sold separately).
