FILTRATION PRINCIPLE: After power on, the built-in pump generates power to form a filtered water cycle. First, dirty water is sucked in from the bottom of the water inlet pipe, and a small amount of water with an oil film enters from the oil skimmer port. The dirty water flows to the filter box, passes through three filter media, completes the filtration cycle,then clean water flows out of the outlet pipe
EASY TO USE:The entire filter body is not placed in the tank and does not occupy the space of the aquarium,only one water inlet pipe in the tank. It is suitable for small space tanks, landscaping tanks with aquatic plants and stones, or with fish that are afraid of the sound of motors. It can hang on the aquarium tank, and the fixing clamp can be adjusted, suitable for glass thickness 0.7inch (18mm),can also be placed next to the fish tank without hanging
UPGRADE FILTER:The motor pump is on the cover, will not scare the fish, and with the fully enclosed filter box and vibration-absorbianga fixed buckle, overall low decibel work. The all-copper motor water pump has a longer life, anti-dry burning design, if the temperature is too high, it will auto off to prevent dry burning damage to the pump.The height of the inlet pipe can adjust, and pipe with sponge cover at the bottom to prevent small fish and shrimps from being sucked away during operation
MULTI-FUNCTION FILTER:3 types of water outlet effects can also add functional effects other than filtration. Rain Shower pipe outlet,the dispersed water flow hits the water surface and can also increase oxygen. Duckbill head water outlet,the water outlet direction of the duckbill head can be adjusted to directionally control the water flow.
