• Soak to Expand,Ready in Minutes - The pond filter media pads are vacuum-sealed for easy shipping, so they may appear thinner upon unpacking. Simply soak them in water for 5–10 minutes, and they will return to their original size without affecting performance.Warm water speeds up the expansion process.
• Maintenance Tips: To maintain optimal filtration, replace the sponge pads every 6 to 12 months—or sooner depending on your pond’s size and fish load.
• Uninterrupted Water Flow: High-porosity sponge design ensures effective filtration without clogging or slowing down water circulation.
