Tired of sluggish shrimp and a tank that turns into a mud pit? This article shows **exactly how to design, build, and tune a high‑performance prawn racing tank** so your prawns sprint from day one. Follow the three proven phases and you’ll avoid costly trial‑and‑error.

## Why Most Prawn Racing Tanks Fail  

- **Undersized dimensions** trap prawns and limit speed.  
- Weak or inconsistent **water flow** leaves oxygen low and waste stagnant.  
- Cheap plastics warp, leak, and create a soggy bottom that slows every shrimp.

These three mistakes turn an exciting race into a slow‑moving mess.

## 3 Phases to a High‑Performance Prawn Racing Tank  

### 1. Get the Dimensions Right  
A tank about **60 cm long × 30 cm wide × 30 cm deep** provides each prawn a clear lane while keeping the water volume manageable.

### 2. Nail the Water‑Circulation Formula  
- Target **two water turnovers per hour**.  
- Use a submersible pump rated **≈ 500 L/h** with a spray bar that spans the rear wall.  
- This creates a **gentle, steady current** that maximizes oxygen and sweeps waste away.

### 3. Choose Durable, Non‑Warp Materials  
- **Acrylic sheets**: crystal clear, impact‑resistant, and won’t bow under heat.  
- Seal seams with **aquarium‑safe silicone**.  
- Install a **smooth glass bottom** so prawns glide without snagging.

## Step‑by‑Step Construction Guide  

1. **Cut acrylic** to the exact dimensions (60 × 30 × 30 cm).  
2. **Assemble the sides** with silicone; let cure **24 hours** for a watertight seal.  
3. **Drill two holes** near the top for the spray‑bar inlet and outlet.  
4. **Mount the pump** and attach the spray bar; run a quick test to verify flow.  
5. **Seal the tank**, then fill with **dechlorinated water**.  
6. **Run the system** for a few hours to stabilize temperature and pH.  
7. **Introduce the prawns** and watch them zip through the lanes within a day.

## Final Checklist & Next Steps  

- ✅ Correct tank dimensions  
- ✅ Proper pump rating and spray‑bar placement  
- ✅ Acrylic construction with silicone seals  
- ✅ Water fully cycled and parameters stable  

Implement these steps and your prawn racing tank will deliver **instant speed, healthy shrimp, and a clean, low‑maintenance environment**.
