When it helps most

The rock is most useful as a safety net at times when ammonia is likely to spike: in a newly set-up tank whose filter bacteria are still building up, after a medication has disturbed the biological filter, or when the tank is temporarily overstocked. It does not replace partial water changes or a mature biological filter, so keep up your usual maintenance alongside it. Test ammonia and nitrite regularly while it is in use, so you can see when it is no longer keeping levels down. Keep any unused rock sealed and dry until needed.

Good to know

Rinse before use and place it in a filter bag in the filter. Replace it when ammonia begins to rise.
