AquaMode 600 Filter Service Kit

Fit a new Aqua One 1c and the Aqua One 1s when you receive the kit. Once per month after this replace the Aqua One 1c and gently rinse the Aqua One 1s in a little aquarium water (it doesnt have to be pristine) to preserve the helpful filtration bacteria that grow in the sponge pores. The Bionoodles can also be rinsed in the same way. Though these only need to be replaced every year or so. A few at a time is best.
