There is a bit of lateral thinking behind this pond filtration set.We wanted to give our pondkeeping friends with large projects the chance to buy a big filtration system that wouldn\'t break the bank. It struck us that it\'s not necessary to go bigger and bigger, so why not use more than one filter and split the pump flow via a Y-piece or T-Piece? The result of this thinking is our exclusive Laguna Pressure-Flo 28000 filter set (our name - not Laguna\'s). This set consists of two pressure filters fed by a powerful solids-handling pump. This system can filtrate a pond sized 28,000 litres. This set contains the following components (please click links below for more information): • PondXpert FreeFlow 18000 pond pump • 2 x Laguna Pressure-Flo 14000 pressure filters * Saving made when compared to buying items separately.
