Its highly permeable filter fabric lets water flow through especially fast, so large volumes of water can be filtered in a short time.\u003c\/p\u003e \u003cp\u003eThe 400 µm filter bag is mainly used for the first clean of a heavily contaminated pond. Coarse debris is reliably retained while water flows through almost unhindered, significantly cutting cleaning time.\u003c\/p\u003e \u003cp\u003eIt's especially effective as a pre-filter combined with finer filter bags. While the 400 µm bag removes coarse contamination, downstream fine filters can work far more efficiently and need cleaning less often.\u003c\/p\u003e \u003ch2\u003eTypical Applications\u003c\/h2\u003e \u003cp\u003eThe filter bag with a 400 µm rating is particularly well suited to fast coarse cleaning and applications with high water flow:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eHeavily contaminated garden ponds\u003c\/li\u003e \u003cli\u003eKoi ponds\u003c\/li\u003e \u003cli\u003eNatural ponds\u003c\/li\u003e \u003cli\u003eSwimming ponds\u003c\/li\u003e \u003cli\u003eCleaning work with a sludge vacuum\u003c\/li\u003e \u003cli\u003eRemoving leaves and plant debris\u003c\/li\u003e \u003cli\u003eCoarse pond sludge\u003c\/li\u003e \u003cli\u003ePre-filtration ahead of finer filter bags\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eThis robust filter bag is excellent for fast dewatering when coarse sludge builds up.

This allows even larger sludge volumes to be filtered quickly without the filter bag clogging.\u003c\/p\u003e \u003cp\u003eThe 400 µm filter bag works especially well as the first cleaning step in pond maintenance, quickly relieving the load on downstream fine filters.\u003c\/p\u003e \u003ch2\u003eEasy Handling During Pond Cleaning\u003c\/h2\u003e \u003cp\u003eThanks to the open mesh structure, collected debris is especially easy to remove after coarse cleaning. The included, reusable cable tie allows the bottom to be opened quickly, so leaves and coarse sludge fall out almost by themselves.\u003c\/p\u003e \u003cp\u003eA key benefit of the 400 µm variant: cleaning the fabric is extremely quick. Because coarse particles don't lodge deep in the pores, a quick rinse with the garden hose is usually enough. Simply turn the bag inside out, rinse and the highly permeable bag is ready for the next use. The robust material also handles sharp plant debris well, keeping it ready for large clean-up jobs.\u003c\/p\u003e \u003cp\u003eBuilt for repeated use, the filter bag is a sustainable, cost-effective way to remove and dispose of pond sludge.\u003c\/p\u003e \u003ch2\u003eWhich Filter Bag Is Right for You?\u003c\/h2\u003e \u003cp\u003eThe right micron rating depends on how contaminated your pond is and the cleaning result you want to achieve.\u003c\/p\u003e \u003ctable width=\"100%\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMicron rating\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e\u003cstrong\u003eApplication range\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e\u003cstrong\u003eTypical use\u003c\/strong\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003e400 µm\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e\u003cstrong\u003eCoarse cleaning\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e\u003cstrong\u003eLeaves, plant debris and coarse sludge with very high water flow.
