The second and arguably more destructive problem of washing filter sponges in tap water is down to the reactive chemicals added to it. These can include chlorine, chloromide and trihalomethanes, and are used to prevent our drinking water for being contaminated by harmful bacteria. Unfortunately they are not able to differentiate those from those bacteria found in your pond filter.
The best way to clean your filters safely is to rinse it in water that has been taken from your pond. When rinsing the waste out of the sponge, try not to remove the entire residue as this will act as nourishment for the next generation of aerobic bacteria. If you are unsure as to when you should clean, it will differ depending on which type of filter you are using. Pressurised filter systems will have an indicator which shows when a high level of waste begins to over pressurise the system.
If you have gravity fed system then the cleaning process should be undertaken just before the filter sponges become blocked. If left this would cause a redirection in the water flow. Warning; never turn off your pond pump as without the constant supply of oxygenated water to the filter, waste will break down anaerobicly within the pond adding even more toxic by products to your water.
