Why we love it
  • Keeps water clean efficiently.
  • Promotes beneficial elements growth.
  • Versatile for various filters.
Main Highlights
  • Mechanical Filtration: The filter media pads can effectively trap debris, food residue, wastes or other impurities in water. Prevent them from entering the aquarium to keep water clean.
  • Fine Sponge Filtration: The egg crate design of the filter media sponges provides much larger contact area with water. Helpful for the accumulation of beneficial elements. Provide biological filtration to fully remove excess damaging substances.
  • Versatile Use: Size: 45 cm L x 28 cm W. The filter floss can be cut to fit all aquarium filters, such as wet/dry filters, canister filters, power filters, etc. Also work great for sumps, ponds or hydroponic systems.
  • Reliable Material: Contain 1 fine pad (black), 1 medium pad (green) and 1 coarse pad (blue). They are made of soft and foldable foam with high elasticity and fine air and water permeability. And they won’t block the normal water flow due to the fluffy inner structure.
  • Easy to Use: Before use, rinse the sponge with cool water to remove the outside dust, then cut it to the proper size and fully put it into the filter chamber. Replace it every 2 to 4 weeks to maintain a healthy water environment. Please unpack and let the pads sit for 24-48 hours before use for best results. Soak them in water will help.
