Making a Splash: Your Ultimate Guide to Building a DIY Stock Tank Pool

So, you’re itching to escape the summer heat and want a pool without the hefty price tag and commitment of a traditional in-ground or above-ground behemoth? You’ve come to the right place! The answer to “How to Make a Stock Tank Pool?” is surprisingly straightforward, yet elegantly customizable. It involves acquiring a stock tank, setting it up safely, installing a filtration system, and adding your personal touches. Think of it as a minimalist pool with maximum style, perfect for lounging and cooling off on those scorching days. Let’s dive into the details.

From Cattle Trough to Cool Oasis: The Essentials

Turning a galvanized steel stock tank into a backyard paradise is easier than you might think. Here’s a breakdown of the necessary steps:

1. Choosing Your Stock Tank: Size Matters (and Material Does Too!)

The size of your stock tank is the first crucial decision. Consider the available space in your yard and how many people you plan to accommodate. Common sizes range from 6ft to 10ft in diameter, with varying depths.

Galvanized Steel: This is the classic and most popular choice. Galvanized steel is durable and rust-resistant, but ensure the galvanization is intact and lead-free – especially important if you have children.
Polyethylene (Plastic): While less common, polyethylene stock tanks are lightweight, durable, and won’t rust. However, they may not have the same aesthetic appeal as galvanized steel.
Inspect for Damage: Regardless of the material, thoroughly inspect the tank for any dents, leaks, or damage before purchase.

2. Site Selection and Preparation: Foundation is Key

Choosing the right location is critical for safety and longevity.

Level Ground: The ground must be perfectly level. Uneven ground puts stress on the tank and can lead to leaks or even collapse. Use a level and shovel to ensure a perfectly flat surface. A slight slope can be deadly!
Solid Base: A solid base is essential to support the weight of the water. Options include:
- Compacted Gravel: Provides drainage and stability.
- Concrete Pad: The most durable option, but requires more effort and cost.
- Pavers: A good middle ground, offering stability and a clean look.
Proximity to Utilities: Consider proximity to a power outlet for the pump and filter, and a water source for filling.
Sun Exposure: Think about the amount of sun the location receives. More sun equals warmer water, but also more algae growth.

3. Plumbing and Filtration: Keeping it Clean

A filtration system is non-negotiable for maintaining clean and healthy water. This involves installing a pump and filter.

Choosing a Pump and Filter: A cartridge filter or sand filter are both suitable options. Size the pump and filter according to the volume of your stock tank. A flow rate of 1000-1500 gallons per hour (GPH) is generally recommended.
Installing the Plumbing: This typically involves drilling holes in the stock tank for the pump and filter connections. Use a hole saw appropriate for the material of your tank.
Fittings and Sealant: Use durable, pool-grade fittings and sealant to ensure watertight connections. Silicone caulk designed for outdoor use is a good choice.
Placement of Intake and Output: Position the intake (suction) near the bottom of the tank and the output (return) near the top to ensure proper circulation.
Skimmer (Optional but Recommended): A surface skimmer helps remove leaves and debris before they sink to the bottom, reducing the workload on the filter.

4. Finishing Touches: Make it Your Own

Now for the fun part: personalizing your stock tank pool!

Sealing the Interior: Consider sealing the inside of the tank with a pool-grade epoxy sealant. This helps prevent rust and makes cleaning easier.
Adding Comfort:
- Pool Noodles: Attach pool noodles around the top edge for comfort and to prevent scratches.
- Seating: Add a small waterproof bench or floating lounge chairs.
Decoration: Get creative with:
- Paint: Paint the exterior of the tank with exterior-grade paint.
- String Lights: Add string lights for ambiance.
- Plants: Surround the pool with potted plants for a tropical feel.
Ladder or Steps: A small ladder or steps make it easier to get in and out of the pool.
Safety First: Never leave children unattended near the pool. Consider a pool cover for added safety.

Frequently Asked Questions (FAQs)

1. How much does it cost to build a stock tank pool?

The cost varies depending on the size of the tank, the filtration system, and any additional features. Expect to spend anywhere from $500 to $1500 or more. The stock tank itself can range from $200 to $500, while the pump and filter can cost another $200 to $500. Additional costs include fittings, sealant, paint, and accessories.

2. How do I prevent rust in my stock tank pool?

Regular cleaning and proper maintenance are key to preventing rust. Use a pool brush to scrub the interior regularly. Sealing the interior with a pool-grade epoxy sealant can also help. Additionally, maintaining proper water chemistry (pH, alkalinity, etc.) can minimize corrosion.

3. How often should I clean my stock tank pool?

Clean your stock tank pool at least once a week, or more often if it’s heavily used. Regularly skim the surface to remove debris and vacuum the bottom to remove sediment. Check and clean the filter as needed.

4. What type of water should I use to fill my stock tank pool?

Use potable water from a garden hose. Avoid using well water unless it’s been tested and treated. Well water can contain minerals and bacteria that can cause problems.

5. How do I winterize my stock tank pool?

To winterize your stock tank pool:

Drain the water completely.
Clean the tank thoroughly.
Disconnect and store the pump and filter indoors.
Cover the tank with a tarp to protect it from the elements.

6. Can I heat my stock tank pool?

Yes, you can heat your stock tank pool. Small electric pool heaters designed for above-ground pools are a good option. Solar pool heaters are another energy-efficient alternative. However, ensure the heater is properly sized for the volume of your tank.

7. How do I control algae growth in my stock tank pool?

Maintaining proper water chemistry and adequate filtration are essential for controlling algae growth. Regularly test the water and adjust the pH, alkalinity, and chlorine levels as needed. Use a pool algaecide as directed. Consider adding a UV sterilizer to the filtration system for extra protection.

8. Do I need a permit to build a stock tank pool?

Permit requirements vary depending on your location. Check with your local building department to determine if a permit is required. Generally, smaller pools (under a certain depth or volume) may not require a permit, but it’s always best to check.

9. How do I add chlorine to my stock tank pool?

Use pool-grade chlorine tablets or granules. A floating chlorine dispenser is a convenient way to maintain consistent chlorine levels. Alternatively, you can use a saltwater chlorinator. Follow the manufacturer’s instructions for dosage and application. Test the water regularly to ensure proper chlorine levels.

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

The ideal pH level for a stock tank pool is 7.2 to 7.8. This range is comfortable for swimmers and helps prevent corrosion and algae growth. Use a pool test kit to monitor the pH level and adjust it as needed with pH increaser or pH decreaser.

11. How do I prevent mosquitoes from breeding in my stock tank pool?

Maintain proper water circulation and filtration to prevent mosquitoes from breeding. Add a small amount of mosquito larvicide (such as Mosquito Dunks) to the water as directed. Empty and clean the tank regularly. A well-maintained pool is less attractive to mosquitoes.

12. Can I use a stock tank pool indoors?

While possible, using a stock tank pool indoors requires careful planning. Ensure proper ventilation and drainage to prevent moisture damage. The floor must be able to support the weight of the water. It’s generally recommended to use a liner to protect the floor. Indoor stock tank pools are best suited for climate-controlled environments. Consider the potential for spills and leaks.
