Media Reactors

Find media reactors, filter socks and media bags for aquarium filtration at EasternMarine Aquariums. These products hold or direct water through different filtration materials, from a simple media bag to a reactor designed for a controlled flow.

Match the holder to the media's instructions and your equipment's dimensions. Some media need gentle flow, while socks and bags must fit securely and remain accessible for cleaning or replacement. Compare the micron rating, fittings and installation requirements before ordering. Explore our filter media collection for compatible materials, or ask our Wiri, Auckland team to help you choose a practical arrangement for your sump. New Zealand delivery options are available online.
