{"title":"Pumps and filters for ponds","description":"\u003cp dir=\"ltr\"\u003e\u003cspan\u003eProperly selected filters and pumps for ponds transform maintenance from a constant concern into a predictable and manageable process. Clean and well-circulated water is fundamental to any healthy garden pond. Without reliable filtration, organic waste, leaves, and excess nutrients quickly accumulate ammonia and nitrate levels, leading to green water and problems for fish. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eIn our category, we offer professional solutions from Sera - one of the leading brands in pond aquatics. Sera's bio-mechanical active pond filters are designed for volumes up to 20,000 liters and operate in three stages: an integrated UV-C lamp with an electronic ballast that destroys unicellular algae and pathogenic microorganisms; a stainless steel plate with micro-perforations that traps fine particles; and a layer of bioactive filter wool for final mechanical and biological filtration. The filters are available individually or as a set with a professional pond pump and hose, allowing you to start the entire system at once.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eFor owners of smaller ponds, Sera offers compact pressure bio-filters for ponds suitable for volumes up to 6,000 or 12,000 liters. Pressure bio-filters have the advantage that they can be installed above the water level, which provides more flexibility when planning waterfalls and streams in the garden.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eAdditionally, we also offer standalone UV-C clarifiers from Sera, which can be integrated into existing pond or aquarium filters. UV-C rays effectively neutralize floating algae and bacteria, keeping the water clear without the use of chemicals.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eWhen choosing a pond pump, it is important to match the water volume with the pump's flow rate - the recommendation is for the entire volume to pass through the filter at least once every two hours. Also, consider the height difference between the pump and the filter, as it affects the effective flow rate.
