The filter itself is the really clever bit. As the water enters the filter unit, it passes through an integrated UVC, shining powerful UV light onto the water which fuses together the small cells of free floating algae that turn your water green. This means that when they then pass through the mechanical and biological media, they are collected along with the dirt and ammonia generated by your pond, removing it from the water and breaking it down over time.

Easy to maintain, the filter sponges are quickly washed in pond water (to protect the bacteria from chlorine in tap water), or replaced periodically with ready to fit Oase sponges, available at low prices from Swell UK.
