Adabuing Replacement Sponge Filter Media Pad – Dual-Density, Compatible with VIVOHOME/VEVOR/VIVOGROW & SUNSUN CPF Filters

Overview

Meet the Adabuing Replacement Sponge Filter Media Pad, a dual-density sponge kit designed for reliable pond filtration. The combination pairs blue, coarse foam with yellow, fine foam to target a range of debris while keeping water flow steady for koi and other pond occupants.

This media pad is built to support both mechanical and biological filtration. By trapping visible debris and food scraps, it helps maintain clearer water while creating a hospitable environment for beneficial bacteria. The design emphasizes a balance between filtration efficiency and water circulation, so you’re less likely to experience flow restrictions during routine cleaning.

How dual-density filtration works

• Blue coarse sponges capture larger particles and debris without clogging the system, aiding mechanical filtration.
• Yellow fine sponges target smaller particles and odors, supporting a deeper level of filtration while preserving water movement.

• Together, the two-density system supports both mechanical filtration and biological activity, contributing to overall water quality.
• These pads help reduce impurities such as food waste and visible debris, helping keep the water cleaner for longer.

Durability and maintenance

The pads are made from soft, collapsible foam that remains elastic and permeable, reducing the risk of impeding flow or harming fish during operation. They are washable and reusable after cleaning, which can extend the life of your pond filtration setup.

Maintenance guidance emphasizes keeping a healthy balance: replace the pads every 2 to 4 weeks in typical setups to maintain water quality. Note that vacuum packaging may make the pads look thinner initially; soaking in water for 5–10 minutes (or warming slightly) helps them regain dimension quickly.

Compatibility and use cases

These sponge pads are designed to fit popular systems, including VIVOHOME, VEVOR, and VIVOGROW units rated at 1580/1840 GPH, as well as SUNSUN CPF-2500/3500 pressure pond filters. They are suitable for koi ponds and other ornamental setups where reliable biological filtration and debris control are important.

What you get

• 2 blue sponges (coarser density) for larger particulates
• 2 yellow sponges (finer density) for small particles and odor control

With a washable, reusable design and straightforward replacement cycle, these pads offer a practical way to maintain pond clarity and overall system health without frequent complete filter changes.
