Stream Pond Pump / Fountain Pump / Filter Pump:
To prevent overflow of the pond filter in conjunction with these powerful pond pumps, we recommend using a Y-adapter. As a bypass, a stream can be additionally supplied, or the performance can be divided between another UVC pond clarifier or pond filter.

The flow rate of the pond pump must be matched to the size of the pond filter. An excessively high flow rate from the pond pump can lead to overflow of the pond filter, which should definitely be avoided. The circulation cycle of the pond and the residence time of the pond water in the pond filter should also be taken into account.

Depending on the type of use, the optimal circulation cycle depends on various factors: fish stock, aquatic plants, sunlight exposure, and desired water clarity. Of course, any additional components of the filtration circuit must also be coordinated.

The following guidelines apply:
Koi Pond / Fish Pond:
• 1 cycle every 3 hours
• 2 circulations in 1 hour (without planting and with high fish stock)

Garden Pond / Plant Pond:
In a pond without fish stock, less circulation is necessary. Here, a daily circulation can be taken as a guideline to enrich the pond water with oxygen and keep the water in motion.

Swimming Pond:
Here, the circulation cycle heavily depends on the planting and personal expectations. The upper limit is 1 time in 2-3 hours, while the lower limit is "no circulation."

Cleaning:
To ensure the proper functioning of the pond pumps, it is necessary to clean them regularly. SunSun has designed the housing so that a handle simplifies the removal of the pond pump, and the housing can be opened without tools – no screws required.
