It's helpful to reserve the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water. <br> After 6 to 12 months' usage, the micro holes of sponge is gradually clogged by the tiny debris. So it is also recommended to replace the sponge once 6 to 12 months or when the sponge gets worn out. <br>
