Protect your wondering anemones from your EcoTech MP10, MP40, and MP60 power heads with this high quality anemone guard. Simply remove your wet-side assembly, remove existing screen, and install this guard back onto your pump as before! This guard not only protects your pump from anemones, but other small creatures like starfish, fish, urchins and snails from getting into your pumps and breaking them. This replaces the existing ecotech guard and does not slide over. This allows for greater water flow through the pump. With the special extra-wide design, more water can flow through the pump and less suction is created on the intake, making it safer for even your small aquarium inhabitants. Made from high quality black PETG plastic, making it 100% aquarium safe.
