Replacement sponge filter for CPF-250/CPF-180 foam filter

Replacement sponge compatible with Sunsun/Polar Aurora CPF-250/CPF-180, VIVOGROW/VIVOHOME 2380 GPH/2630 GPH, and Goplus 10000 L/H pond filters. Blue pond filter media size: 25.4 cm (L) x 25.4 cm (W) x 3.5 cm (H) x 3 pieces. Yellow media size: 20 cm (L) x 20 cm (W) x 2.9 cm (H) x 3 pieces. Note: Due to vacuum packaging, the pond filter pads may appear thinner, but this does not affect filter efficiency. You can soak them in water for 10 minutes to restore their original size. These pond filters for outdoor ponds are designed to withstand multiple rinses and be reused without breaking or deteriorating. To optimize sponge performance, we recommend replacing the sponges every 6 to 12 months, or sooner depending on the pond's biological surface area.
