The 42" X 21" Replacement Pond Filter Foam Set is the ideal solution for keeping your pond filter efficient and your fish healthy. This set comes with three different foam grades: fine, medium, and coarse, specifically designed for gravity-fed, flow-through filters. Each foam type plays a crucial role in maintaining water quality by filtering out various sizes of debris and providing a habitat for beneficial bacteria.

Foams should be checked regularly and replaced when they no longer spring back into shape after being squeezed. This helps ensure the filtration system continues to operate effectively and maintains balanced levels of filter bacteria, which is essential for a healthy pond environment.

The foam set is versatile and can be easily trimmed to fit most filter sizes. Simply cut the necessary holes to suit your specific filter model.

• Contains three different foams: fine, medium, and coarse
• Compatible with most gravity-fed, flow-through filters
• Easily cut to size for a perfect fit
• Helps maintain healthy bacterial levels in your pond
• Foams spring back into shape when functional, indicating the need for replacement
