Pond and Fountain Pumps
A pond pump is installed to circulate oxygen in the water to sustain the life of a pond. Liners Online supply a range of pond pump sizes. To determine which model is most suitable you need to take into account whether it is for a pond containing fish or one containing just aquatic plants. A pond containing Koi fish will need a bigger pump than that containing just goldfish as they create more pollution (amount of fish faeces and urine alters the rate at which water becomes less pure). Pond pump model sizes are based on wattage and flow rate. All models operate at a maximum depth of 2 meters.
