Hydor Replacement Sponge Prime 10

The filter sponge is cut to size for the external filter Hydor Prime 10 and is easy to replace.

Moving water is absolutely necessary for most aquarium fish, because this is the only way to ensure effective filtering and gas exchange. They are also familiar with a certain amount of current from their habitat and, not least, serve their well-being. The aquarium should also always be filtered to ensure consistently good water quality.
