Thickness Selection Guide
· Small tanks (diameter ≤6m): Recommended 1.0mm–1.5mm galvanized sheet.
· Medium tanks (diameter 6m–15m): Recommended 1.5mm–2.0mm galvanized sheet.
· Large tanks (diameter ≥15m / height ≥2m): Recommended 2.0mm–3.0mm galvanized sheet.
· Cost-Effective: 50% lower investment than concrete ponds, 80% shorter construction period.
· High Efficiency: Supports 3-5 times stocking density than traditional earthen ponds, easy for feeding, oxygenation, and harvesting.
· Environmentally Friendly: Water-saving (over 60% vs earthen ponds), compatible with recirculating aquaculture systems (RAS) for zero discharge.
· Flexible Application: Customizable sizes (diameter 3-30m, height 1-3m), suitable for various terrains and scenarios.
· Terrain Requirement: Requires a flat and solid ground (concrete floor, compacted soil base, gravel ground, etc.), avoiding sharp objects to prevent puncture of the canvas liner.
· Water Adaptability: Suitable for freshwater, seawater, and various aquaculture water bodies (pH 6.5~8.5), meeting the breeding needs of different fish/shrimp species such as bass, catfish, prawns, and koi.
· Equipment Matching: Can be matched with aerators, water pumps, sewage treatment equipment, and recirculating water systems to build an intelligent aquaculture system.
· Aquaculture: High-density farming of bass, catfish, shrimp, koi, and ornamental fish.
· Agriculture: Irrigation water storage, livestock drinking water, rainwater harvesting.
· Engineering: Emergency water storage, sewage treatment, landscape ponds.
· Custom size, color, and accessories (drain valve, overflow pipe, ladder, observation window).
· One-stop solution for recirculating aquaculture systems (RAS), aeration systems, and temperature control.
