What is the Largest Stock Tank You Can Buy?

The undisputed heavyweight champion of the stock tank world is generally considered to be the 14-foot diameter stock tank, boasting a substantial capacity of approximately 1670 gallons. While custom options might exist, this is typically the largest readily available size from major manufacturers. Its colossal size makes it ideal for large livestock operations, serious homesteaders, or those seeking a substantial water reservoir.

Understanding Stock Tank Sizes: More Than Just a Number

Stock tanks aren’t just simple containers; they’re crucial pieces of equipment for livestock management, agricultural practices, and even innovative recreational uses. Knowing the typical sizes, materials, and considerations surrounding these tanks is paramount for informed decision-making.

Material Matters: Poly vs. Galvanized Steel

The vast majority of stock tanks come in two primary materials: polyethylene (poly) and galvanized steel. Each offers distinct advantages and disadvantages:

• Poly Tanks: Poly tanks are known for their durability, resistance to rust and corrosion, and lighter weight. They’re often easier to move and handle, and their smooth surface is easier to clean. However, they can be susceptible to UV degradation over time, especially in harsh climates, though many manufacturers incorporate UV inhibitors.

• Galvanized Steel Tanks: Steel tanks offer robust strength and can withstand more physical abuse than poly tanks. The galvanization process protects against rust, but over time, especially with hard water, corrosion can still occur. They are heavier and more challenging to relocate once filled. Historically, steel tanks were more common, but poly tanks have gained popularity due to their lower maintenance.

The largest stock tanks are generally available in both poly and galvanized steel, although the poly versions might be less common due to the challenges of molding such a large piece of plastic.

Beyond Diameter: Depth is Key

While the diameter (the width across the tank) is the most common measurement used to describe a stock tank, depth is equally crucial. A 14-foot diameter tank might come in various depths, significantly impacting its overall capacity. Make sure you understand both dimensions when choosing a tank.

Capacity Considerations: Gallons and Livestock Needs

Calculating the correct stock tank size involves understanding your livestock’s daily water requirements. A general rule of thumb is that cattle require between 8 and 12 gallons of water per day, horses can drink 10 to 15 gallons, and sheep and goats need 1 to 3 gallons. Consider factors like climate, feed type, and activity level, as these can all influence water consumption.

A 1670-gallon tank could comfortably support a significant herd of cattle for several days, assuming regular replenishment.

Alternative Uses: More Than Just Watering Animals

Stock tanks are remarkably versatile and have found uses far beyond their original intended purpose:

• Swimming Pools: Stock tank pools have become incredibly popular, offering a cost-effective and aesthetically pleasing alternative to traditional swimming pools. Their size makes them suitable for a refreshing dip on a hot day.

• Aquaponics and Hydroponics: Stock tanks provide an ideal container for establishing aquaponics or hydroponics systems, allowing for efficient and sustainable food production.

• Emergency Water Storage: The large capacity of stock tanks makes them valuable for storing emergency water supplies in case of droughts or other unforeseen circumstances.

• Rainwater Harvesting: Stock tanks can be connected to rainwater harvesting systems to collect and store rainwater for irrigation or other non-potable uses.

FAQs: Your Burning Stock Tank Questions Answered

Here are 12 frequently asked questions about stock tanks to give you even more information:

1. How much does a large stock tank cost?

The cost of a large stock tank, like the 14-foot model, varies greatly depending on the material (poly vs. steel), manufacturer, location, and any additional features. Expect to pay anywhere from $1,500 to $4,000 or more. It’s always recommended to get quotes from multiple suppliers.

2. What is the best material for a stock tank in a cold climate?

Both poly and steel tanks can work in cold climates. However, poly tanks are generally considered to be slightly better because they are less prone to cracking from freezing water expansion. Steel tanks can become brittle in extreme cold. Regardless of the material, proper winterization techniques (like using a tank de-icer) are essential.

3. How do I clean a stock tank?

Regular cleaning is crucial for maintaining water quality. Drain the tank completely and scrub the interior with a stiff brush and a solution of water and bleach (a diluted solution, not full strength). Rinse thoroughly before refilling. Avoid using harsh chemicals or detergents that could contaminate the water.

4. Can I use a stock tank for human drinking water?

Generally no. Stock tanks are not manufactured to the standards required for potable water storage. They might contain materials that leach into the water and are not food-grade. Use only certified potable water storage tanks for drinking water.

5. How long will a stock tank last?

The lifespan of a stock tank depends on the material, climate, and maintenance. Poly tanks can last 10-20 years or more with proper care, while galvanized steel tanks might last 15-25 years, but can be subject to rust and corrosion. Regular cleaning and maintenance are essential for extending the lifespan of any stock tank.

6. How do I prevent algae growth in my stock tank?

Algae thrive in sunlight. Placing your stock tank in a shaded area or using a tank cover can significantly reduce algae growth. You can also use algaecides specifically designed for livestock water tanks, but follow the instructions carefully. Beneficial bacteria products are also an option to naturally combat algae.

7. How do I repair a leak in a poly stock tank?

Small leaks in poly tanks can often be repaired with a plastic welding kit or a specialized poly repair patch. For larger cracks, it’s best to consult a professional repair service.

8. Can I bury a stock tank?

While it’s possible to bury a stock tank, it’s generally not recommended unless it’s specifically designed for underground use. Standard stock tanks are not built to withstand the pressure of surrounding soil and can collapse. Underground water storage tanks require robust construction.

9. How do I move a large, full stock tank?

You don’t. It is almost impossible to safely move a large, full stock tank. Drain it completely before attempting to move it. Even when empty, large steel tanks are heavy, and you will likely require heavy equipment like a tractor or forklift.

10. What is the ideal water level for a stock tank?

Maintaining a consistent water level is crucial for ensuring adequate water availability for livestock. A good rule of thumb is to keep the tank at least half full. Monitor the water level regularly, especially during hot weather or periods of high demand. Automatic water level controllers can be used to maintain a consistent level.

11. Are there any safety concerns with stock tanks?

Yes. Always supervise children around stock tanks to prevent drowning. Ensure that livestock can easily access the water without getting trapped or injured. Regularly inspect the tank for sharp edges or other hazards. Use appropriate safety measures when cleaning or repairing the tank. Electrocution is possible if a stock tank is near an electrical source, ensure proper grounding and safe wiring.

12. Where can I buy a large stock tank?

Large stock tanks can be purchased from agricultural supply stores, farm supply retailers, online marketplaces (like Amazon and Tractor Supply Co.), and directly from manufacturers. Compare prices and shipping costs before making a purchase. Check customer reviews to assess the quality and reliability of the product.

In conclusion, the 14-foot diameter stock tank represents the upper end of readily available options, offering a substantial solution for various water storage needs. But remember to carefully consider your specific requirements, including material, capacity, and intended use, to make the best choice for your situation. Doing your homework and seeking expert advice will ensure you choose the perfect stock tank for years to come.
