It also works as a biological filter starter for ponds by helping create the perfect biological balance in your filter. Simply dilute a tablet in a bucket of pond water for 2 hours, switch off the pump for 1-2 hours and add the contents of the bucket to your filter to allow them to colonise the filter media without being washed through, then turn your pump back on.
