鱼缸 壁挂式 过滤盒子 Aquarium wall-mounted filter box

这个壁挂式的鱼缸过滤器 与 小型的鱼缸水泵配合使用，盒子里加入过滤海绵，起到过滤鱼缸水体杂质的作用，效果良好。以前都是几天换水，现在只加水，不换水。This wall-mounted aquarium filter works in conjunction with a small aquarium water pump. By adding filter sponges to the box, it effectively filters out impurities in the aquarium water, achieving good results. In the past, we had to change the water every few days, but now we only need to add water without having to change it.
