This 2 Tub Bio System is a brand new filter for ponds around 2000 UK gallon. It has the more efficient Pro filter design features and the modern re-designed drainage that removes a lot more dirt. It’s also much cheaper to build and requires less media, while still giving much better performance than the average mass-produced pond filter. This filter is so easy to clean you don’t even get your hands dirty. Also as your pond and fish grow so can the filter. You simply add another tub, it’s as easy as that. This simple and very efficient design is now the most popular DIY filter on the planet. This filter is built using 110 ltr tubs with the cheaper 2 inch (50mm) pipework and can run on 70 ltr of K1 media.
