It’s helpful to reserve the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water. After 6 to 12 months’ usage, the micro holes of sponge is gradually clogged by the tiny debris, the beneficial bacteria won’t have as much living space as before. That’s when the sponge filter starts to lose its efficiency. So it is also recommended to replace the sponge once 6 to 12 months or when the sponge gets worn out.

### ⭐⭐⭐⭐⭐ Great Price & Value for your Dollars!
*by A***S on January 4, 2021*

These seemed to be slightly thicker than the original ones that came with the canister. They fit tight without gaps along the tray. Big fan of having extra filters around for my fish.

### ⭐⭐⭐⭐ Perfect
*by C***N on November 9, 2019*

Perfect for filtering and good quality.
