The \u003cstrong\u003eMountain Tree Star Filter Brush\u003c\/strong\u003e is a koi pond filter brush that catches fish waste, uneaten food and plant debris before it reaches your biological media. Its star-shaped filaments also give beneficial bacteria plenty of surface to settle on. Koi Water Hyderabad supplies it in two lengths, 12 × 60 cm and 12 × 100 cm, for new pond builds and filter upgrades across India.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Koi Keepers Choose the Star Filter Brush\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCatches solid waste early.\u003c\/strong\u003e Traps coarse debris in the first chamber, so less of it reaches and clogs your biological media.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMore surface on every filament.\u003c\/strong\u003e Mountain Tree states its six-pointed star filament gives about four times the specific surface area of conventional single-thread brushes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSupports biological filtration.\u003c\/strong\u003e The filaments give beneficial microorganisms room to colonise inside your filter.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStainless-steel core.\u003c\/strong\u003e Twin support wires in 304\/316 stainless steel, as specified by the manufacturer for corrosion resistance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEasy to hang and lift out.\u003c\/strong\u003e An injection-moulded open hook makes installation and cleaning simpler; plastic caps protect both ends.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBuilt for long service.\u003c\/strong\u003e The manufacturer states a service life of more than five years under suitable conditions.

Fish waste, uneaten food, decaying leaves and other coarse particles get caught along the way. Collecting these solids in one place keeps them out of downstream media and makes them easier to flush out.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBiological filtration.\u003c\/strong\u003e The same filaments give beneficial bacteria a large surface to grow on. With steady water flow, good oxygen levels and a mature filter, these bacteria help convert ammonia and nitrite into less harmful nitrate. The brush supports this process; it works alongside dedicated biological media, regular water testing and partial water changes, not in place of them.\u003c\/p\u003e\n\n\u003ch2\u003eThe Star-Shaped Filament Advantage\u003c\/h2\u003e\n\u003cp\u003eStandard filter brushes use round, single-thread bristles. Mountain Tree's six-pointed star filament, which the manufacturer describes as its own patented design, adds ridges along the length of every fibre. Those extra edges give fine waste more places to cling and bacteria more surface to colonise. Mountain Tree rates this at about four times the specific surface area of a conventional single-thread brush.\u003c\/p\u003e\n\u003cp\u003eThe brush is also designed to be water-permeable, so water flows through it rather than being blocked, helping keep the chamber working evenly.\u003c\/p\u003e\n\n\u003ch2\u003eWhere to Install It: The First Filter Chamber\u003c\/h2\u003e\n\u003cp\u003eThe Star Filter Brush works best as a pre-filter in the first mechanical chamber, where dirty water from the pond enters. Hang brushes vertically in rows across the chamber so water has to pass through them, not around them.\u003c\/p\u003e\n\u003cp\u003eIt is especially useful in systems without a separate settlement chamber, vortex or pre-filter. It can also be used in an aquarium sump's overflow section, side filtration and other mechanical chambers.\u003c\/p\u003e\n\n\u003ch2\u003eSuitable Applications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eKoi ponds\u003c\/li\u003e\n  \u003cli\u003eBackyard and garden ponds\u003c\/li\u003e\n  \u003cli\u003eFish farms\u003c\/li\u003e\n  \u003cli\u003ePublic aquariums\u003c\/li\u003e\n  \u003cli\u003eCompatible freshwater aquarium sump filtration\u003c\/li\u003e\n  \u003cli\u003eWater-treatment systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNot recommended for seawater filtration.\u003c\/p\u003e\n\n\u003ch2\u003eMaterials and Construction\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilaments:\u003c\/strong\u003e fine polypropylene with a six-pointed star profile, set cylindrically around the core.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore:\u003c\/strong\u003e two stainless-steel support wires, specified as 304\/316 stainless steel.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHook:\u003c\/strong\u003e injection-moulded suspension hook at the top for hanging and removal.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnds:\u003c\/strong\u003e protective plastic caps on both ends for safer handling.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterials:\u003c\/strong\u003e stated by the manufacturer to be non-toxic and EU RoHS compliant.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth style=\"border:1px solid #ccc; padding:8px; text-align:left;\"\u003eSize\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ccc; padding:8px; text-align:left;\"\u003eModel number\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ccc; padding:8px; text-align:left;\"\u003eFilament\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ccc; padding:8px; text-align:left;\"\u003eCore wire\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border:1px solid #ccc; padding:8px;\"\u003e12 × 60 cm\u003c\/td\u003e\n      \u003ctd style=\"border:1px solid #ccc; padding:8px;\"\u003eMTF124060\u003c\/td\u003e\n      \u003ctd style=\"border:1px solid #ccc; padding:8px;\"\u003ePolypropylene, star-shaped\u003c\/td\u003e\n      \u003ctd style=\"border:1px solid #ccc; padding:8px;\"\u003e304\/316 stainless steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border:1px solid #ccc; padding:8px;\"\u003e12 × 100 cm\u003c\/td\u003e\n      \u003ctd style=\"border:1px solid #ccc; padding:8px;\"\u003eMTF1240100\u003c\/td\u003e\n      \u003ctd style=\"border:1px solid #ccc; padding:8px;\"\u003ePolypropylene, star-shaped\u003c\/td\u003e\n      \u003ctd style=\"border:1px solid #ccc; padding:8px;\"\u003e304\/316 stainless steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eBoth sizes share the same filament, core and construction.

Hang the brushes vertically so incoming water passes through them before reaching your biological media.\u003c\/p\u003e\n\n\u003ch3\u003eWhich size should I choose: 60 cm or 100 cm?\u003c\/h3\u003e\n\u003cp\u003eBoth sizes have the same filament and construction; the difference is length. Choose the one that fits your chamber depth while staying fully submerged. If you are unsure, share your chamber dimensions with our team.\u003c\/p\u003e\n\n\u003ch3\u003eHow many brushes do I need?\u003c\/h3\u003e\n\u003cp\u003eIt depends on your chamber width, water depth and flow rate. Brushes should be arranged so water cannot bypass them. Send us your filter chamber size and we will help you work out a layout.\u003c\/p\u003e\n\n\u003ch3\u003eWill this brush clear my pond water or remove ammonia on its own?\u003c\/h3\u003e\n\u003cp\u003eNo single product does that. The brush traps solid waste and provides surface for beneficial bacteria. Clear, healthy water depends on the whole system: biological media, oxygenation, sensible stocking, regular testing and maintenance.\u003c\/p\u003e\n\n\u003ch3\u003eHow often should I clean it?\u003c\/h3\u003e\n\u003cp\u003eCheck monthly and flush when waste builds up.
