Raise Koi Like a Pro—AC 316 Stainless Steel Koi Filter Brushes Make Your Filter Chamber Complete
Update time: 25-09-11 Views: 8
"Crystal-clear water, healthy koi" is the motto every koi keeper repeats, but achieving an "air-tank" look is never about daily water changes alone. It relies on a scientific, highly efficient filtration system. Among all the mechanical + biological stages, there is one small yet decisive "supporting actor"—the filter brush. Today AC lets you meet our star product: the AC Koi Filter Brush, a "film-forming, noise-reducing, corrosion-proof" filtration tool that turns koi keeping into true "lazy mode".
1. Why Must a Filter Chamber Contain Brushes?
1. First barrier for suspended solids
Koi eat a lot and excrete even more. Uneaten food, leaves and dust become suspended particles. AC's brand-new PET five-pointed-star bristles have a rough surface and rich porosity, intercepting particles >50 µm quickly and easing the load on downstream biological media.
2. Flow stabiliser + noise killer
Bottom drains or cyclones often shoot water violently into the next chamber, stirring sludge and creating splash noise. The brush's 316 stainless-steel spiral core builds a 3-D channel that disperses flow evenly, muffling sound almost instantly.
3. Luxury apartment for nitrifiers
Combined surface area of bristles + core equals 2.3× that of ordinary bio-rings of the same volume. A mature bio-film forms within 28 days, continuously converting NH₄⁺/NO₂⁻ and giving your koi an ammonia-free home.
2. Four Hard-core Advantages of AC Koi Filter Brushes
1. National-standard 316 stainless steel 1.8 mm core
Usable in fresh, brackish or marine water; chlorine, acid and alkali resistant; service life ≥5 years—truly "one pond, zero rust".
2. Five-pointed-star PET bristles
92% rebound rate, no deformation after repeated flushing; ROHS-compliant, zero plasticiser, zero heavy metals—no risk of secondary pollution.
3. Spiral hydrophobic structure
Cuts flow resistance by 30%. With the same head, pump power drops ≈8%, saving large farms thousands of kWh every year.
4. Hang or lay—your choice
Built-in tie holes suit chambers 40-120 cm deep. Hang them or cut to lay in the overflow zone—flexibility MAX. Maintenance? One minute with a pressure washer saves 70% water compared with classic filter foams.
3. Field Data: From "Milky Water" to "Air Tank" in 28 Days
A 40-ton koi pond in Foshan, Guangdong used common plastic brushes + bio-rings; water transparency <30 cm, NH₄⁺ 0.8 mg/L.
After switching to 80 cm × 60 pcs AC brushes:
Day 7 — suspended solids -65%, water bright;
Day 14 — NH₄⁺ down to 0.2 mg/L, NO₂⁻ 0.05 mg/L;
Day 28 — transparency ≥80 cm, koi patterns clearly visible, feed intake +18%.
Owner's comment: "I used to clean foams three times a day; now I rinse the brushes once a week—half the work, half the cost!"
4. How to Choose and Install
1. Sizing: Filter-chamber L×W×H (cm) ÷1,500 ≈ quantity of 80 cm brushes needed.
2. Flow order: Inlet → brushes → bio media → outlet; brushes should occupy about 30% of total filter volume.
3. Maintenance: light rinse every 3 months, full clean every 6 months. Never use washing powder or bleach—keep that bio-film alive!
