Easily installed with universal click-fit fast couplings, the "Pressure-Flo" filter is designed to work with solids-blocking or solids-handling pumps to provide mechanical and biological filtration with UV sterilisation. First the water is filtered mechanically as it is pumped into the filter chamber, where dirt and debris are broken down and become trapped in the foam filtration media. Then the water passes into the biological filtration compartment, where "BioSpheres" bio-media house beneficial bacteria that convert the waste products to preserve healthy water quality. In the final stage of filtration, water passes by an integrated UV-C steriliser lamp, the ultraviolet rays inhibiting the growth of single-celled waterborne algae. To make the system even more user-friendly, an easy-view cleaning indicator shows when debris needs to be removed from the foam filters. Because the system is pressurised, it can maintain optimum water circulation whether installed above ground or partially buried, making it suitable for any pond or waterfall location.www.lagunaponds.comComplete foodIn "Koi adult" the Czech company Dajana Pet offers a complete food for adult and larger fish, appropriate for feeding throughout the year.
