[Three-in-one oxygen-enriched filtration waveform] Rapid oxygen enrichment angle and flow rate can be adjusted. Soil adsorption matches the filtration box to more completely filter impurities in the water and simulate the real wave generation environment of fish. for fresh water and l SeawaterThe filter design should be fully immersed in fresh water and salt water. The removable filter cartridge matches the filter material freely. It is more convenient and faster to change the filter material at any time as needed. Built-in adjustable flow rate The maximum flow rate of a powerful filter can reach 500 l Sq. The product has a built-in adjustable outlet nozzle, the outlet direction can be adjusted from left to right, up and down. energy saving, quiet, stable stable filter, magnetic core permanent stainless steel, long service life. Very quiet, the ultra-quiet sealing colloids operate with less than 35 DB of noise. Very energy efficient, the 8 W power and very low energy consumption are ideal for aquariums of 40 - 120 liters.
