Filter Sponges and Media for Aquarium Fish Tank 19.6x19.6x1.57(35PPI*1Pc)

The pore size of sponge filters plays a crucial role in their performance. The 25PPI (pores per inch) pore size enhances the water passing rate and effectively filters out debris and fish waste. The 35PPI pore size offers good water permeability, filtration efficiency, and flexibility. For better filtration of fine fish waste and impurities, the 50PPI pore size is recommended to cultivate nitrifying bacteria effectively.

Large-sized filter pads measuring 19.6"x19.6"x1.57" are available, allowing users to cut them to fit their specific aquarium or pond filter needs. To compare the size of these filter pads with other brands, the volume calculation formula can be used: 19.68(L)x19.68(W)*1.57(H)=608. The larger the parameter values, the bigger the sponge, ensuring the best value for money.

Sponge filters provide both mechanical and biological filtration, trapping substantial amounts of waste while resisting clogging easily. The pore size, measured in PPI, determines the number of pores in the sponge unit area. The higher the PPI, the more pores the sponge contains, and the better the filtration performance.

For optimal results, it is recommended to use a combination of sponge filters with different pore sizes. This approach ensures comprehensive filtration, catering to the specific needs of your aquarium or pond.

These filter pads are dye-free and safe for aquatic pets. They are commonly used as pre-filters for wet/dry filters, catch basins, and tank filters. Regular cleaning is required, and the pads are reusable and durable after cleaning.

The filter pads are vacuum-sealed and compressed for space-saving storage and easy transportation. They are suitable for all types of aquariums. Before use, the pads should be unpacked and restored to their original size according to the instruction steps provided.

Overall, these high-quality sponge filters offer excellent mechanical and biological filtration, ensuring a healthy and thriving aquatic environment for your aquarium or pond inhabitants. The variety of pore sizes caters to different filtration needs, allowing you to achieve the best possible water quality for your aquatic pets.
