Anemone Guard for Hygger 1600GPH (14w) Wave Maker Aquarium Pump. This anemone guard slides over the powerhead and protects wondering anemones from being sucked up and killed in your powerheads. Also great for preventing snails, shrimp, ad other small creatures from being harmed in your wave makers. Special tapered design allows for increased water flow even when partially clogged with debris!! To install the guard, insert guard over your pump and make sure that you line the power cord cutout with the pre-made slot. Then simply push the guard firmly over your pump and you are good to go! Made from fish safe plastic. NOTE: This is quite a snug fit so be sure to apply a fair bit of pressure when installing this guard.
