This filter effectively removes algae and sludge from my freshwater tank. The 3D fiber structure catches small particles well. I’ve washed the filter balls twice and they still perform strongly. Great for maintaining water clarity.
Dylan Mitchell –
Works well in a 120-liter marine tank. The filter maintains good flow and keeps water clean. After washing, it still holds its shape and performance is stable.
