Preparing Your Stock Tank for the Summer Season

Before filling your stock tank, ensure the ground is perfectly level and capable of supporting thousands of pounds of water weight. An unlevel tank causes uneven water pressure, which can warp the metal or stress the seams over time. Placing a heavy-duty rubber utility mat under the tank protects the bottom from sharp rocks and acts as a thermal barrier against the cold ground.

For galvanized steel tanks, addressing rust prevention early is crucial to extending the life of the pool. Apply a marine-grade sealant or a rust-preventative coating to any internal seams or potential scratch points before adding water. If using a chlorinating system, a protective liner or specialized epoxy coating is highly recommended to prevent the corrosive chlorine from eating through the zinc galvanized coating.

Filter Pump – Intex Krystal Clear Cartridge Pump

Standing water quickly turns into a breeding ground for mosquitoes, bacteria, and algae, making a reliable filtration system absolutely non-negotiable. Stock tanks do not have built-in filtration, so forcing water to circulate through a filter is the only way to keep it clear and sanitary. Without a pump, you would be dumping and refilling hundreds of gallons of water every few days, which is both wasteful and exhausting.

The Intex Krystal Clear Cartridge Filter Pump (1,500 GPH) is the ideal match for stock tanks ranging from 8 to 10 feet in diameter. It delivers high-velocity water circulation that forces debris into the filter cartridge, keeping the entire water volume moving. The built-in GFCI plug ensures electrical safety, while the replaceable Type A or C cartridges make routine maintenance straightforward.

Installing this pump requires cutting two holes into the side of your metal or plastic tank using a metal-cutting hole saw. You must seal these connection points with marine-grade silicone and pool inlet/outlet jets to prevent slow leaks.

• Flow rate: 1,500 gallons per hour
• Best for: Tanks up to 4,000 gallons
• Replacement filter type: Intex Type A or C
• Requires: 1.5-inch diameter hoses and plunger valves (sold separately)

This pump is perfect for families who want a reliable, cost-effective filtration setup with straightforward cartridge replacements. It is not ideal for those who prefer zero-maintenance systems, as the cartridges must be rinsed weekly and replaced every fortnight during peak summer use.

Surface Skimmer – Intex Deluxe Wall Mount Skimmer

Floating debris like leaves, pollen, and drowning bugs will quickly sink to the bottom of your pool if they are not caught early. Once debris settles, it decays, staining the tank floor and consuming your chlorine supply at an alarming rate. A surface skimmer intercepts these floating contaminants automatically before they can sink, keeping the surface pristine.

The Intex Deluxe Wall Mount Surface Skimmer hooks directly into your filter pump’s suction port to draw in floating debris. Its floating cover adjusts automatically to the water level, ensuring continuous skimming even as water evaporates or splashes out. The durable polypropylene construction resists pool chemicals and UV damage, making it a rugged addition to a busy backyard setup.

Because stock tanks have thick, rolled metal rims, the standard over-the-wall bracket may require slight modification. Bending the bracket slightly or securing it with a small block of wood or a clamp ensures a snug, rattle-free fit on a round tank wall. You also need a pump with a minimum flow rate of 800 GPH to generate enough suction for the skimmer to function effectively.

• Mounting style: Adjustable wall bracket
• Material: Corrosion-resistant polypropylene
• Compatibility: Requires pump with minimum 800 GPH flow rate
• Maintenance: Removable strainer basket for quick cleaning

This accessory is a must-have for stock tanks situated under trees or in windy yards where organic debris is constant. It is not suitable for tiny stock tanks under 6 feet where it takes up too much swimming space, or for systems running under-powered pumps.

Solar Cover – Intex Round Solar Pool Cover

Metal stock tanks are incredibly efficient heat conductors, meaning they lose warmth rapidly overnight and can overheat under direct afternoon sunlight. A solar cover acts as a physical barrier that traps heat in the water while drastically reducing water evaporation. It also prevents windblown dust and leaves from settling into the water when the pool is not in use.

The Intex Round Solar Pool Cover features heavy-duty thermal bubbles that float directly on the water’s surface to absorb and transfer solar heat. The lightweight material makes it easy for one person to pull off and roll up before a swim. Because stock tanks come in standardized diameters, this round cover provides edge-to-edge coverage that fits like a glove.

Standard stock tanks often have slightly different interior dimensions than standard above-ground pools, meaning you may need to trim the edges. The durable material can be easily cut with sharp household scissors without fraying or losing its thermal properties. Be sure to store the cover in the shade when off the pool, as direct sunlight can degrade the plastic bubbles over time.

• Material: Heavy-duty 120-micron plastic
• Function: Heat retention and evaporation reduction
• Sizing: Easily trimmed with scissors for custom fits
• Storage: Must be kept out of direct sunlight when dry

This cover is essential for families in cooler climates who want to extend their swimming season into late spring and early autumn. It is less necessary for those in scorching desert climates where keeping the water cool is the primary challenge.

Chlorine Dispenser – Game Derby Duck Floating Dispenser

Maintaining a consistent sanitizer level is the single most important step in preventing algae blooms and dangerous bacterial growth. In a small-volume stock tank, chemical levels can fluctuate wildly after a single swim session or a heavy rainstorm. A floating dispenser provides a slow, controlled release of chlorine to keep the water safe and clear.

The Game Derby Duck Floating Dispenser holds up to three 3-inch chlorine tablets and features an adjustable chlorination rate ring. Its heavy-duty, UV-resistant housing prevents the plastic from cracking under harsh sunlight, while the fun duck design adds a playful touch to the pool. The expandable basket allows you to adjust the chemical output precisely based on your tank’s water volume.

You must never allow chlorine tablets to sit directly on the bottom of a galvanized steel stock tank, as concentrated chlorine will quickly eat through the protective zinc coating and cause rapid rusting. The dispenser must float freely at all times; tethering it to the center of the pool can prevent it from getting stuck against the metal side walls.

• Capacity: Holds up to three 3-inch tablets
• Adjustment: Variable-flow chlorination ring
• Material: UV-resistant, heavy-duty plastic
• Safety feature: Secure twist-lock cap

This dispenser is perfect for busy families who want a low-maintenance, set-it-and-forget-it solution for daily sanitation. It is not designed for non-chlorine sanitizing systems like active copper ionizers or bromine setups that require specialized dispensing hardware.

Handheld Vacuum – Water Tech Pool Blaster Catfish

No matter how good your filter pump is, heavy debris like sand, dirt, and small pebbles will inevitably sink to the bottom of the tank. Standard pool vacuums that hook up to the filter pump can be cumbersome to prime and hook up in a small space. A self-powered handheld vacuum allows you to clean up the tank floor in minutes without disrupting your plumbing.

The Water Tech Pool Blaster Catfish is a cordless, rechargeable pool vacuum designed specifically for spot-cleaning small pools and spas. It features an independent motor and reusable filter bag, meaning it does not rely on your pool pump’s suction to work. The lightweight design can be used by hand for steps and shallow areas or attached to any standard telescoping pool pole.

The reusable filter bag is excellent for catching sand, silt, and leaves, but ultra-fine clay or algae dust may pass through the standard mesh. Upgrading to a micro-filter bag or wrapping the standard bag in a fine nylon stocking helps trap these microscopic particles. Always rinse the vacuum with fresh water and dry it completely before storing it to prevent battery contact corrosion.

• Power source: Lithium-ion rechargeable battery
• Run time: Up to 45 minutes per charge
• Debris capture: Reusable all-purpose filter bag
• Attachment: Compatible with standard telescopic poles

This handheld vacuum is a game-changer for parents whose kids constantly drag grass and dirt into the pool on their feet. It is not intended for deep, commercial-sized swimming pools or for heavy-duty leaf removal after winter.

Floating Thermometer – Inkbird IBS-P01B Bluetooth

Water temperature dictates not only your swimming comfort but also how your pool chemicals behave. High temperatures cause chlorine to dissipate rapidly, while cooler temperatures can make the water uninviting for the kids. Monitoring the temperature without having to walk out to the pool and peer over the edge saves time and effort.

The Inkbird IBS-P01B Bluetooth Floating Thermometer features a high-contrast LCD screen for quick glances and a built-in Bluetooth transmitter. This allows you to check the current temperature and historical trends directly from your smartphone via a free app. The double-sealed, IPX7 waterproof body ensures the internal electronics stay dry and functional all season long.

While the Bluetooth range is excellent, thick metal stock tank walls can sometimes degrade the wireless signal if you are deep inside the house. Placing the thermometer near the side of the tank closest to your home helps maintain a strong, uninterrupted connection. Ensure the battery compartment cap is tightened firmly after replacing the AA batteries to prevent water intrusion.

• Connectivity: Bluetooth smart-phone tracking
• Waterproof rating: IPX7 certified
• Power: 2 x AA batteries (not included)
• Data logging: Displays current temp and historical trends

This high-tech thermometer is ideal for detail-oriented homeowners who like to monitor their pool status from the comfort of their couch. It is overkill for those who prefer a simple, old-school analog thermometer and do not mind walking out to read it.

Pool Step – Main Access Easy Entry Walk-In Step

Climbing over the slippery, tall rim of a stock tank can be incredibly dangerous, especially for wet children or older adults. Traditional stock tanks sit about two to three feet off the ground, presenting a significant trip hazard if you try to step directly over the side. Dedicated pool steps provide a stable, non-slip path into and out of the water, preventing slips and falls.

The Main Access Easy Entry Walk-In Step features wide, textured steps and dual handrails for maximum stability. The heavy-duty plastic construction is chemical-resistant and UV-treated to prevent cracking or fading under constant exposure to sun and chlorine. The open-side design allows water to circulate freely behind the steps, preventing stagnant water pockets where algae can hide.

Because stock tank floors are flat and slippery, these steps must be properly weighted to prevent them from floating or sliding. You will need to fill the internal weight chambers with pool sand or clean gravel before submerging them in the tank. Additionally, ensure the step feet are resting on a protective rubber mat to prevent any rough plastic edges from scratching the tank floor.

• Material: UV-resistant polyethylene
• Weight capacity: Up to 350 pounds
• Safety: Dual handrails and non-slip treads
• Installation: Requires internal sand weighting for stability

This step system is essential for families with toddlers, older relatives, or pets who need a secure, gradual entry point. It is not suitable for tiny 6-foot tanks where the steps would take up more than half of the usable swimming area.

Submersible Light – Loftek Waterproof LED Lights

Night swims are one of the best parts of owning a backyard pool, but swimming in a pitch-black metal tub can be intimidating and unsafe. Adequate illumination allows you to see the bottom of the pool clearly, ensuring no foreign objects or nocturnal critters have slipped inside. Submersible lights transform your stock tank into a glowing, resort-like backyard centerpiece after sunset.

Loftek Waterproof LED Lights feature multiple color modes, brightness levels, and a convenient remote control. They come equipped with powerful built-in magnets and suction cups, making them incredibly easy to mount to either metal or plastic stock tanks. The IP68 waterproof rating means they can remain submerged continuously without leaking or shorting out.

On galvanized steel tanks, the built-in magnets will cling firmly to the side walls without requiring any adhesive or suction cups. However, if your tank has a protective epoxy coating or liner, the magnetic pull might be slightly reduced, requiring the backup suction cups. Remember to remove the lights and dry them out if you plan to winterize the pool, as freezing temperatures can damage the battery seals.

• Waterproof rating: IP68 submersible
• Mounting options: Built-in magnets and suction cups
• Control: RF remote control with multi-color selection
• Power source: 3 x AA batteries per light

These lights are perfect for families who love hosting evening gatherings or want to create a relaxing, colorful ambiance for night-time soaking. They are not necessary for those who only use their stock tank during peak daylight hours.

Water Clarifier – Clorox Pool&Spa Super Clarifier

Even with a great filter pump, micro-particles like sunscreen, body oils, and fine dust can pass right through your filter cartridge, leaving the water looking dull and cloudy. These tiny suspended particles are too small for the filter to trap on its own, meaning the water remains hazy despite hours of filtration. A water clarifier binds these particles together, making them large enough for the filter to grab.

Clorox Pool&Spa Super Clarifier features a highly concentrated formula that quickly clears cloudy water without affecting your pool’s chemical balance. It coagulates microscopic debris into larger clumps that are easily trapped by your cartridge filter or sink to the bottom for vacuuming. A single small dose is often enough to restore sparkling clarity to a typical 700-gallon stock tank.

Because stock tanks have a much lower water volume than traditional pools, you must calculate your dosage carefully to avoid over-treating. Adding too much clarifier can actually have the opposite effect, acting as a dispersant and making the water cloudier for longer. Run your filter pump continuously for 12 to 24 hours after adding the clarifier, then thoroughly rinse the filter cartridge to remove the trapped gunk.

• Formula: Concentrated polymer clarifier
• Dosage: Extremely low volume needed for stock tanks
• Filter compatibility: Safe for cartridge, sand, and DE filters
• Effect: Coagulates microscopic suspended solids

This clarifier is a lifesaver after high-use weekend pool parties where sunscreen and sweat have left the water cloudy. It is not a substitute for sanitizer and will not clear up green water caused by active algae growth.

Floating Cooler – Intex Mega Chill II Inflatable

Stepping out of a cool stock tank onto scorching hot deck boards or grass just to grab a cold drink is a quick way to ruin your relaxation. Having a floating beverage station keeps your drinks ice-cold and within arm’s reach at all times. It keeps the kids hydrated without them tracking wet grass back and forth across the yard.

The Intex Mega Chill II Inflatable Floating Cooler is built with heavy-duty, puncture-resistant vinyl that stands up to rough backyard use. It can hold up to 72 cans plus ice, or can be used as a floating base for a traditional chest cooler up to 48 quarts. It features heavy-duty handles, six built-in cup holders, and a removable lid to keep the sun off your ice.

In a smaller stock tank, a fully loaded floating cooler can take up a significant amount of swimming space. You can use the built-in connectors to tether the cooler to the outside rim of the tank, or only float it during relaxed soaking sessions. Be careful not to over-inflate it on hot days, as rising temperatures will cause the air inside to expand and potentially strain the seams.

• Capacity: Holds up to 72 cans plus ice
• Versatility: Can hold an entire 48-quart cooler chest
• Material: 0.4mm heavy-duty vinyl
• Features: 6 built-in cup holders and heavy-duty handles

This floating cooler is the ultimate luxury for adults looking to lounge with cold beverages during long weekend afternoons. It is not ideal for small tanks crowded with active, splashing children who might easily flip the cooler.

Keeping Your Stock Tank Clean and Safe All Year

As summer fades, your stock tank pool needs proper off-season preparation to ensure it survives the winter without rusting or cracking. If you live in a climate with freezing winters, draining the tank completely is the safest option to prevent expanding ice from rupturing the seams. Store your pump, hoses, and accessories in a dry, temperature-controlled space like a garage or basement to prevent freeze damage to the plastic components.

For those in milder climates who choose to keep the tank filled year-round, securing a heavy-duty, winter-proof cover is essential. Run the filter pump for a few hours each day and maintain a low chlorine level to keep the water from stagnating. Inspect the tank regularly for any signs of rust or debris accumulation, addressing minor issues immediately before they become costly spring headaches.

Conclusion

With the right set of accessories, your stock tank pool will transition from a simple metal tub into a high-performance backyard retreat. By investing in quality filtration, safety steps, and easy-to-use cleaning tools, you ensure a safe and crystal-clear swimming environment for your family. Prepare your tank correctly, keep the water moving, and get ready to enjoy a stress-free summer of splashing.
