Therefore, if there is a sharp part, move the fan blade upwards or press it. Look for the correct position and try again. The fan will be a bit slow at first, but it will get faster as the bubble rises. 2Q: This product is not well packaged, the filter beads inside are leaking out?A: This product may leak out of the filter beads because of the problem of reversing the placement in the logistics. When you find out that the filter beads inside are leaking out, please isolate the cover of the net and align it with the bottom net buckle to reinstall it. 3Q: The air pump of this product is too small to move at all, and the air pump is too noisy.A: It must use a pump of more than 5W. The problem with the large sound of the air pump is that the depth of the water in the aquarium is related. The water in the fish tank is too shallow to suck with noises. So the depth of the water is not too shallow.
