Replacement foam advice 

If a filter uses more than one foam component – never replace all foams at the same time.  Replace 25-30% of the foams then wait a couple of days and repeat, make sure you arrange the foams by order of grade from fine to coarse.  This reduces the risk of killing nitrifying bacteria that are essential to maintaining a functioning pond filter. 

Feeding should be stopped or considerably reduced until all the foams are replaced.
