Triple filtration for clearer water
The filtration media combines two layers of high-density material to trap visible debris and fish waste as water passes through. An activated carbon layer speeds odor reduction and helps counter yellowing, contributing to a crisper-looking aquarium and a more inviting light transmission for your aquatic life. While results may vary with tank setup, many hobbyists notice a more consistent water appearance and a calmer glass surface after a routine change.
