Do not clean the Bioballs once they are cycled, or you will risk killing off all the beneficial bacteria that you need to filter your water. Another use for Bioballs: fill your tank's overflow box. They will keep your snails and other animals from going down the overflow as well as quiet the overflow greatly.
