Everything You Need to Know About Stock Tank Pool

Stock tank pools (Horse trough pools) are budget-friendly alternatives to traditional swimming pools.

These large metal or plastic containers, originally used for livestock, have become a popular backyard solution.

They offer a simple way to cool off without the high costs or complicated setup of standard pools.

This guide will walk you through everything you need to know about setting up, maintaining, and customizing your stock tank pool.

You’ll find tips for creating a fun and functional backyard oasis, from picking the right size to adding filters.

What is a Stock Tank Pool (Horse Trough Pool)

A stock tank pool (horse trough pool) is a large container made from galvanized metal or plastic originally meant for holding water for farm animals.

Now, these tanks serve as small swimming pools in backyards nationwide. They’re round or oval,

Size and Space Considerations

Stock tank pools (horse trough pools) fit easily in most yards.

The most common sizes are 6, 8, and 10 feet in diameter, making them great for small spaces where a full-sized pool won’t work.

Their 2-foot depth (some 10-foot tanks reach 28 inches) makes them safe for families while still being deep enough to sit and relax.

Before buying, please measure your space carefully to ensure you have room for the pool, walking around it, and any extras like chairs or decks.

Materials You’ll Need to Setup a Horse Trough Pool

Setting up your stock tank pool [horse trough pool] requires several items to ensure it works well and stays clean.

Preparing everything before you start will make the process much smoother and faster.

Choosing the Right Stock Tank

When picking a stock tank (horse trough pool), you have two options: galvanized steel or polyethylene plastic.

Steel tanks with a metal finish look more stylish but can rust over time, especially if you use chlorine.

Plastic tanks cost less and won’t rust, but they may crack from sun damage or cold weather. Both types should last about 10 years with good care.

Consider how many people will use it and your available space for size.

A 6-foot tank works for 2-3 people, while 8-foot or 10-foot tanks allow more room to stretch out.

The bigger the tank, the more water it holds, so consider your water bill and the weight (a filled 8-foot tank can weigh over 2,000 pounds).

Filtration Equipment

Clean water is a must for any pool. For your stock tank pool [horse trough pool], you’ll need:

Pool pump (look for one rated for small pools)
Filter system (sand filters need less upkeep than cartridge types)
Inlet and outlet valves (to connect the pump)
Plunge valves (to shut off water flow when needed)
Hoses (to connect everything)

A good filtration setup keeps the water moving and clean, which means less work for you and a more pleasant swimming experience.

Additional Supplies Checklist

Beyond the basics, these items will help with setup and upkeep:

Hole saw (2¾ inch for cutting valve holes)
Metal file (to smooth cut edges)
Plumbing tape (prevents leaks)
Marine-grade sealant (makes connections watertight)
Water treatment (chlorine or hydrogen peroxide)
Water test strips (to check chemical levels)
Pool skimmer (for removing leaves and bugs)
Ground cover or sand (if placed on grass)
Level (to make sure your site is flat)
Grounding rod (if using metal tank for safety)

You might also want a pre-fill water filter to remove chemicals from tap water when filling your pool.

Preparing the Perfect Spot for Your Stock Tank Pool

You must set the right spot before bringing home your stock tank (horse trough pool).

Good placement ensures your pool stays stable, drains properly, and lasts longer. A well-chosen location also makes your pool more enjoyable to use.

Finding Level Ground

Flat, level ground is crucial for your stock tank pool (horse trough pool). An uneven surface can cause several problems:

Water will be deeper on one side than the other
The tank might warp over time due to uneven pressure
It can become unstable or even tip when filled

Use a level tool to check your chosen spot. If you find slight slopes, you can dig down on the higher side or build up the lower side with sand.

Take time with this step—it’s much harder to fix after your pool is filled with water, which can weigh over 2,000 pounds for an 8-foot tank.

Surface Options

Several surfaces work well under stock tank pools [horse trough pools]:

Concrete slabs: Ideal because they’re already level, stable, and won’t shift. Perfect if you have an existing patio.
Crushed stone or gravel: Provides good drainage and prevents mud. Lay a weed barrier underneath first, then 2-3 inches of gravel. Compact it well and check for levelness.
Sand bed: A budget-friendly option. Create a 2-inch layer of sand, dampen it, then compact it firmly. This creates a soft, level base.
Pavers or stepping stones: Can create a neat border around your pool while providing a stable base.

Avoid placing your stock tank directly on grass or dirt. If you do, it will sink and become mud when water splashes out.

Whatever surface you choose, ensure it can support the weight of a filled pool and won’t shift over time.

Step-by-Step Guide to Setting Up Your Pool

Once you have your tank and spot ready, it’s time to set up your stock tank pool (horse trough pool). This part takes some work but can be done in one afternoon with the right tools.

Installing the Inlet and Outlet Valves

These valves let water flow to and from your filter system:

Position your tank and mark spots for two holes—one higher (for the outlet) and one lower (for the inlet).
Use a 2¾-inch hole saw to cut through the metal or plastic. Go slowly to avoid making rough edges.
Use a metal file to smooth any sharp edges around the holes.
Clean up all metal bits with a vacuum to avoid cuts.
Apply plumbing tape to the valve threads for a better seal.
Add marine-grade sealant around the fitting edges to make them watertight.
For the outlet valve (higher hole): Insert from inside the tank, then tighten the nut on the outside. Make sure the air hole faces up.
For the inlet valve (lower hole): Follow the same steps as the outlet.
Attach plunger valves to both inlet and outlet. These let you shut off the water flow when needed without draining the pool.
Let the sealant dry completely before testing with water.

Setting Up the Pump and Filter

With the valves in place, you can now connect your filtration system:

Place your pump and filter near the tank, but not so close that splashes will affect the electrical parts.
Add filter media to your filter tank. Sand or glass media works better than cartridges for these pools.
Connect hoses from the plunger valves to the pump and filter according to the arrows showing the water flow direction.
Make sure all connections are tight to prevent leaks.
Fill your tank with water, but leave about 2 inches of space at the top to allow movement.
Once filled, plug in your pump to start water flowing through the system.
Check for leaks around all connections and tighten as needed.
Add your chosen water treatment (chlorine or hydrogen peroxide) according to package directions.
Let the system run for a few hours to filter the water before entering.

This basic setup gives you a working pool with clean, filtered water that will stay fresh instead of getting slimy or full of bugs.

Adding a Filtration System for Clean Water

A good filter keeps your stock tank pool [horse trough pool] clean and clear. You’ll fight against algae, bugs, and cloudy water without one.

Sand vs. Cartridge Filters

Sand filters need less work—you only replace them every few years, making them more cost-effective long-term.

Glass media filters are even better than sand. Cartridge filters clean well but need frequent cleaning and replacement, adding ongoing costs.

Water Treatment Options

Most pool owners use chlorine to kill germs. Food-grade hydrogen peroxide (35%) is a natural option that won’t rust metal tanks and lets you reuse water on plants.

Test regularly to maintain proper levels.

Innovative Ways to Customize Your Stock Tank Pool

Painting and Decorating Ideas

Paint the outside with rust-resistant outdoor paint in bright colors or patterns.
Add waterproof LED lights for nighttime swims.
Place potted plants around the edges for a natural look.
Use weather-resistant cushions and pillows on nearby seating.

Adding Decks and Surrounds

Build a simple wooden platform around your tank for easy access and a place to sit. Consider a gravel base to keep the area dry and clean.

For privacy, add bamboo screens or tall grasses. Install flat stones or pavers around the pool to create a walking path and prevent mud. Small pergolas offer shade during hot days.

Tips for Maintaining and Cleaning Your Pool Year-Round

Daily and Weekly Maintenance

Check water levels daily and top off as needed. Test pH levels twice weekly using test strips. Skim leaves and bugs from the surface every day.

Clean the pump filter weekly to keep water flowing. Wipe the sides with a soft cloth to stop algae growth.

Add small amounts of chlorine regularly rather than large doses occasionally.

Seasonal Care Tips

In summer, due to heavy use and heat, increase cleaning. In the fall, remove fallen leaves promptly. Winter requires draining or using a cover if not in use.

Spring calls for a deep clean before refilling. Consider a pool cover for any season when not in use.

Stock Tank Pool Ideas That Will Modify Your Backyard

Landscaping Around Your Pool

Plant low-maintenance flowers nearby for color. Use stones to create a path to your pool.

Add solar ground lights for evening safety and style. Create a flat, level base with sand or gravel.

Shade and Privacy Solutions

Install removable umbrellas for hot days. Use outdoor curtains on tension rods for quick privacy.

Set up potted trees that can be moved as needed. Build simple wooden screens that match your yard style.

Common Problems and How to Fix Them

Dealing with Leaks

Small holes can appear from normal wear. Use water-safe silicone sealant for tiny leaks. For bigger holes, try a metal patch kit made for stock tanks.

Check pipe connections often – tighten loose fittings with a wrench. If your drain plug leaks, replace the rubber gasket or use a plumber’s tape.

Test for hidden leaks by marking and checking the water level after 24 hours.

Preventing Rust and Damage

Apply clear marine-grade sealant to metal surfaces yearly.

Put rubber mats under the tank to stop bottom rust. Keep metal tools away from the pool to avoid scratches. Touch up paint chips quickly before rust starts.

In winter, empty completely and store upside down in a dry place if possible.
