Velda (VT) Vt Filter Zeolite 5000 ml

VijverTechniek Zeolite is a natural stone that binds nitrates and phosphates. Thanks to this quality, Zeolite is an important filter medium to keep pond water healthy and free of algae. If you change the Zeolite once every season, you will keep the pond water in optimum condition. Simply fill the enclosed net with Zeolite and rinse it several times with plenty of water. Then it can be placed in the filter.
