These kits make filtration simpler and smarter whether you maintain a small backyard pond or a large koi setup. At Aquabead, we understand the need for clean, healthy water without overhauling your entire system. That’s why we offer high quality media and retro kits manufactured by GC TEK that is engineered for performance, durability and efficiency.
Media retro kits are designed to restore or upgrade old filter systems with new, high performance media. Over time, biological and mechanical pond filter media degrade, reducing their ability to trap waste and support beneficial bacteria. Thus, by using a media retro kit, you improve water flow and filtration efficiency. These kits help reduce ammonia, nitrites and organic debris, keeping your pond water crystal clear and your fish healthy. This approach ensures your pond runs better without replacing the entire system.
We only offer premium media and retro kits, including:
Each type plays a vital role in achieving balanced, healthy water quality. The mix of media types ensures both mechanical and biological filtration work efficiently in harmony.

One of the key advantages of media and retro kits is their compatibility with existing filters. There's no need to invest in a new filtration system when a simple upgrade can achieve outstanding results. Additionally, these kits are compatible with pressurized bead filters, gravity-fed filters, and other setups. Retrofitting is easy; you simply replace or add new media using the kit. It’s that straightforward.
