The water flows from the bottom up through your filtration system. To optimize efficiency:

  • Place the soft, more open side of the FilterFirst pad down against the sponge.

  • Follow with the polishing pads, ensuring their soft side is also facing down.

This layering method is designed to improve both water clarity and quality.

Pro Tip for Goldfish Owners: Since goldfish tend to produce more waste than tropical fish, you may need to rinse or replace the pads more frequently to maintain optimal performance.
