If you want to create a suitable environment for your fish, it is essential that your pond water is kept clean and crystal clear by regularly replacing your filter foams or media. Foams are graded by pore size, with coarser sponges catching the bulk of the debris and finer ones polishing what gets through, while biological media such as ceramic or plastic shapes provide the surface area bacteria need. Matching a replacement to the grade and the position it sits in keeps the filter working the way it was designed to.

Your foams are home to the bacteria quietly converting ammonia, so a little care keeps that colony thriving. Swap them in stages rather than all at once and the media left in place will seed the new material, and give anything you are keeping a rinse in a bucket of pond water, which preserves the bacteria that tap water would clear away. Keep coarse and fine grades in the order your filter was designed to use them, and replace like for like from the grades here.
