The Sunsun JY Series Surface Skimmer effectively removes unsightly oil slicks, debris, and floating residue from your aquarium's water surface. Oil film reduces light penetration and gas exchange, and this skimmer solves that problem immediately. Available in two models, JY-02 ($3\text{W}$) and JY-03 ($5\text{W}$), both deliver a consistent 300L/H flow rate. They feature a unique floating intake that automatically adjusts to the changing water level (up to 4cm), ensuring continuous and effective skimming. The flow rate and air suction are adjustable. Contains a filter sponge to trap fine particles. Essential for planted tanks and high-tech setups.
