PVC Biofloc Fish Farming Tank – Description

Overview:

A PVC Biofloc Fish Farming Tank is a durable, portable, and cost-effective solution designed for intensive aquaculture using the biofloc technology system (BFT). These tanks are ideal for growing a variety of fish species in a controlled environment with minimal water exchange, promoting sustainable and profitable fish farming.

Key Features:

�� Material Composition:

• Constructed with high-strength, UV-resistant PVC-coated tarpaulin fabric (usually 600-900 GSM).

• Supported by a galvanized iron (GI) or MS (mild steel) frame with anti-rust coating for long-term outdoor use.

�� Tank Shape and Size:

• Available in circular, square, or rectangular shapes, with circular being the most common for biofloc.

• Sizes range from 1,000 liters to 50,000+ liters, customizable as per the requirement.

�� Design & Portability:

• Foldable and lightweight design for easy transportation and installation.

• Quick setup—can be assembled within 1–2 hours without heavy machinery.

�� Water Retention & Leakage Protection:

• Double-stitched and heat-welded seams to prevent leaks.

• Resistant to tearing, UV rays, and chemical corrosion.

Biofloc System Compatibility:

The tank is designed specifically for the biofloc aquaculture method, which:

• Enhances water quality by converting toxic nitrogenous waste into microbial protein.

• Reduces water exchange requirements.

• Promotes fish health and boosts growth rates through nutrient-rich flocs.

Suitable Species:

• Tilapia

• Catfish

• Pangasius

• Rohu, Mrigal

• Prawns/Shrimp (with proper salinity adjustment)

Advantages:

• ✅ Low operational cost due to minimal water usage.

• ✅ Environmentally friendly farming practice.

• ✅ Ideal for urban, backyard, and commercial fish farming.

• ✅ Modular system—easy to expand fish farming operations.

Optional Add-ons:

• Aeration system (air pumps, diffusers)

• Drainage outlet and valve

• Water quality monitoring kit

• Shade nets for temperature control

Common Sizes:

Tank Size & GSM Variants

Offered tanks and how GSM vs size is handled

• MEGATEX Biofloc fish culture tank offers coated biofloc tanks in 550, 650, 750, 850, 1,050 GSM for capacities from 4,000 L to 100,000 L (diameters ~2 m to 10 m)
• MEGATEX Round PVC biofloc tank Diameters from 2 m to 20 m, with thicknesses 550, 650, 800 GSM and protective HDPE liners.
• Biofloc aquaculture tank for a 13 m diameter, 1.45 m height, capacity ~168,000 L, they list GSM 650 variant, among others.
• 11 m diameter, 1.45 m height, 750 GSM for ~120,000 L.
• 5 m diameter, 1.45 m height, 20,000 L, 650 GSM sheet.
• e.g. 3,000 L (2 m × 1 m) up to 40,000 L (6.5 m diameter) in GSM 550 / 600 / 760 variants.
• MEGATEX supply all gsm and multiple diameters in  Biofloc tank for fish farming.

From these examples, you can see that:

• Lower GSM (e.g. 550 GSM) is suitable for smaller tanks, moderate usage, or protected locations.
• Mid GSM (650, 750, 800 GSM) is a balanced choice for many typical commercial biofloc tanks.
• High GSM (1,000, 1,250, etc.) is used for large, heavy-duty installations or long life, especially in exposed, high UV, or heavy-use settings.

GSM‑Wise Selection Guidelines & Trade offers

• Expected lifespan & durability: Higher GSM gives more years of safe use.
• Exposure to UV / Sunlight: More exposed systems benefit from thicker GSM.
• Size & stress: Larger diameter and greater height impose more mechanical stress, favor higher GSM.
• Budget constraints: Thicker GSM costs more, so balance cost vs life.
• Risk factors (abrasion, animals, tools contact): In high wear zones, thicker material helps.

Here’s a rough guideline (these are indicative and may vary by manufacturer and site conditions):

“GSM-Wise” Tank Variants
