Tips for Usage and Maintenance:
Maintenance of Sponges:
The sponge will need to be rinsed every time it becomes dirty, about once every 1 to 4 weeks. 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. So it is also recommended to replace the sponge once 6 to 12 months or when the sponge gets worn out.
