| Evolution Aqua’s New Pure Pond Filter The PURE Pond Filtration System is a new type of filter designed for the smaller pond and for use on quarantine systems. The PURE Pond filtration systems utilise Evolution Aqua’s Pure Pond and Kaldnes K1 media, which allows the filter system to achieve optimum results. Being an Evolution Aqua filter, they are incredibly easy to install, use, and clean. The PURE POND Filtration System is available in two sizes, for ponds up to 5,000 litres or ponds up to 10,000 litres, with or without a circulating pump. How it works As pond water is pumped through the filtration system, it passes through four successive filtration stages: STAGE 1. UV-C filter, (11 Watt on the PURE POND 5,000 model and 18 Watt on the PURE POND 10,000 model). This stage will clear green water, which is caused by single cell algae, and prevent it from returning. STAGE 2. Mechanical stage, where pond water passes through a basket containing Kaldnes K1 Media, removing solid waste from the water. STAGE 3. Aeration stage, where pond water passes through a trickle filter screen, which replenishes the water’s oxygen levels and encourages gaseous exchange with the atmosphere. STAGE 4. Biological stage, where pond water passes through a basket holding the award winning, PURE POND bio balls (not included) promoting beneficial bacteria colonies. This will help the filter keep the pond water healthy and safe for your fish. The PURE Pond 5000 Model is supplied with: - 11 Watt UV
