What’s Included and How It Helps 4-pack bio sponge pads with distinct densities to capture large and small debris: 1x Coarse (Black), 2x Medium (Green), 1x Fine (Black)

12-pack white floss pads for finer filtration, helping to reduce fine particles and improve clarity

Vacuum-sealed packaging keeps pads compact during storage; use immediately or let them regain thickness after unpacking

Multilayer filtration: coarse capture for big debris, medium pads for mid-sized particles, and fine pads for tiny particulates

Flexible installation: you can combine pads for stronger filtration or run lighter setups for smaller tanks

Usage Tips and Maintenance Restore to normal thickness by unpacking and letting sit 24–48 hours, or soak 5–10 minutes for immediate use

Replace or rinse sponge pads every 6–12 months for optimal performance; replace the white polishing pad every 2–6 weeks

Rinse bio sponge pads with tank water rather than tap water to help preserve beneficial bacteria

Why It Works for Your Tank These pads work together to help purify water quality and support clean, healthy habitats for aquariums, turtle tanks, and fish tanks

While results can vary based on tank size and bio-load, many hobbyists notice clearer water and improved turbidity control when using a well-muited multi-density filtration set
