• Built-in filter sponges and biochemical materials, and integrate functions of filtration, oxygenation, and wave making.
• The angle of the water outlet can be adjusted in four directions (about 120° horizontally, about 30° up and down).
• The outlet flow can be adjusted by the adjustable valve.
• Energy saving, low operation sound, full submersible.
• Scientific structure, assembly, and disassembly without tool.
• Bottom suction type, with enough suction. It can directly suck from the bottom to the top and then filter from the top to the bottom. The dirt can be firmly locked in the filter sponge.
