No other filter medium is as widely used or has been as extensively tested and proved. How do they work Whichever installation design you choose, the method of water introduction to the chamber will have an effect on the efficiency of the brushes. Generally the water should flow into the chamber at slow speed rather than being jetted in under pressure. Water travelling at high speed not only causes turbulence, which will disturb settled material, but it can also wash off some of the waste which has been trapped successfully in the brushes. How to use Before purchasing Black Knight brushes, you should decide what type of filter design will be best for your pond. How to use Black Knight Filter Brushes If you have a small pond with a few goldfish and a couple of koi then a single chamber with three to six lines of brushes will be ideal. For a more demanding situation, it will be necessary to use a much larger chamber or to link two or three together. These can all contain brushes or you can use them in the first and second chambers and then use a stone medium such Alfagrog in the last chamber. Maintenance When a significant amount of waste has built up on the brushes, it should be flushed away. The brushes should be flushed using buckets of pond water.Cleaning in this way will retain most of the beneficial bacteria that live on the brushes but the rotting waste is removed and cannot do any more harm to the water quality.\u003c\/p\u003e","brand":"SKS Wholesale","offers":[{"title":"Default Title","offer_id":57232528703865,"sku":"FM237","price":9.78,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/0955\/9929\/files\/13999_ccdac7aa-e6a7-49ce-9ee8-eb2651320d5c.jpg?v=1778254036"},{"product_id":"k-koi-replacement-foam-set-1-x2-foam-x1-wool","title":"K-Koi Replacement foam Set 1 (x2 foam x1 wool)","description":"\u003cp\u003e0\u003c\/p\u003e","brand":"Kockney Koi","offers":[{"title":"Default Title","offer_id":57232528802169,"sku":"FS126","price":21.63,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/0955\/9929\/files\/1308resized111_7804cadc-bf50-4707-8cba-4c2422d26c76.jpg?v=1778254036"},{"product_id":"oase-replacement-filter-foam-set-for-filtoclear-20000-30000","title":"OASE Replacement Filter Foam set for FiltoClear 20000-30000","description":"\u003cp\u003eFor FiltoClear 20000\/30000. The heart of a filter are its filter sponges - especially this filter sponge set, which combines the blue and red sponges in a small space. Red filter sponges have fine filtering properties, while the blue ones are coarse. This means that, depending on the flow speed of the water, small or only larger particles get stuck in the sponges and are thus withdrawn from the pond water. But they not only do the classic filtration, they also provide the smallest bacteria with plenty of living space. This small biological oasis in the red filter sponges ensures that any toxins that have arisen in the pond are converted: Toxic substances are converted into harmless but algae-stimulating substances (nitrification), which in turn are converted into naturally occurring gases (denitrification).
