The more fish you have the more frequently a pad should be replaced. Maintenance of Sponges: The sponge will need to be rinsed every time it becomes dirty about once every 1 to 4 weeks. After 6 to 12 months’ usage the micro holes of sponge is gradually clogged by the tiny debris. 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. And carbon ammonia and phosphate pads will become chemically exhausted over time so they are suggested to be replaced at least once per month.
