A pond in the summer is not equal to a pond in the winter. As the seasons’ change, the ecology of the entire pond changes as well. If your pond filter system is not adequate for summer weather, the fish, plants, and you will all suffer for it. Even the best filter must have a GPH (gallons per hour) capacity of at least ½ your pond’s volume. But which is the “best” water filter will depend on what you need the filter to do.
Pond Filters to Reduce Algae Growth
Summer is the peak season for algae infestations in ponds. One reason for this is because nitrogen concentrations tend to build up quickly in warmer weather. To prevent this, a biological filter is necessary.
To remove algae already in the water, you may want to use a water filter with a UV Clarifier. UV Clarifiers kill bacteria and algae as they pass under the UV light. They are low maintenance, as the UV light and filter pads only need to be changed once a season.
The Best Pond Filters to Keep Fish Healthy
If your pond is stocked with fish, you may notice that they are more active during the warm summer months. This is also the time where most growth occurs. This means that the fish will produce more waste than in the winter months, so it is important to have a good mechanical filter, which can trap the large particles of waste.
Proper aeration is also vital in the summer because warm water does not hold as much oxygen as cool water. Your fish will become sick quickly if the pond water is under-oxygenated. Keep them happy and healthy by using a pond filter, which agitates the water. This could be a pressurized filter. Or, you can get a filter kit which includes a water feature, such as the pond boss® Complete Filter Kit with Pump.
