Ideal Water Circulator used for internally filtering the aquarium water. The air pipe attached with the internal filter provides oxygenation\/aeration to the aquarium water. Absorbs dirt, keeps water clear, suitable for any aquarium and all kinds of filtration. Completely submersible motor, safe & quiet operation. Suitable for fresh and sea\/marine water. Removes physical particles by suction, assists in biological filtration in the filter media. The filter media\/sponge filters the dirt and traps it in its pores. It is important to clean the sponge regularly. While cleaning the sponge\/filter media, it is recommended to use the aquarium water and not Tap water. Performing regular maintenance can prolong the lifespan of the pump. During Installation, ensure the power plug is inserted into the power socket outlet at the higher point. This is to ensure that water will not backflow via the wire to the socket outlet or via the air pipe. Do not run dry the pump. In case your aquarium is sufficiently aerated\/oxygenated you could block the air intake in the filter.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
