Description
Fit a new Aqua One 69c and the Aqua One 69s when you receive the kit. Once per month after this replace the two Aqua One 69c and gently rinse the Aqua One 69s in a little aquarium water (it doesnt have to be pristine) to preserve the helpful filtration bacteria that grow on the sponge pores. The Aqua One Bionoodles can also be rinsed in the same manner.
