Moreover, you should take into account the ponds circulation cycle as well as the period of time of the pond water in the pond filter.According to the type of usage, the ideal circulation cycle depends on different factors: the fish population, aquatic plants, the quantity of sunlight or the desired water clarity. It goes without saying that, as the case may be, there are further components of the filter circuit that are to be coordinated, if necessary.The following information may serve you as a guideline:Koi pond / Fish pond:• 1 cycle per 3 hours• 2 circulations in 1 hour (without plantings and with large fish population)Garden pond / Plant pond:Regarding a pond without fish, there is less circulation necessary. One circulation in a day can be taken as a guideline in order to enrich the pond water with oxygen and to keep the water in constant movement.Swim pond:In this case the circulation cycle is highly dependent on the planting and the individual claim.The upper limit is to be made at 1 x in 2-3 hours, the lower limit at “no circulation”.
