9 Essential Pool Supplies for Keeping Temporary Water Clean

Setting up a temporary splash pool or quick-set ring pool in the backyard promises instant summer relief, but that pristine water can turn into a cloudy, green swamp in just a few hot days. Unlike permanent inground pools with massive filtration systems, small-scale temporary pools require a strategic, hands-on approach to keep the water safe and inviting. Equipping yourself with the right tools ensures you spend your weekends floating in crystal-clear water rather than draining, scrubbing, and refilling a ruined investment.

The Unique Challenges of Managing Temporary Pool Water

Temporary pools, ranging from small inflatable splash pads to metal-frame quick-set setups, suffer from a severe lack of water volume. Because they hold fewer gallons than traditional pools, small environmental changes—like a heavy rainstorm, a hot afternoon, or a handful of sweaty swimmers—can instantly throw the entire chemical balance out of whack. The water heats up rapidly in the summer sun, creating a breeding ground for rapid algae growth and bacteria multiplication.

Furthermore, the retail kits for these pools often ship with underpowered, bare-minimum filtration systems. Without the heavy-duty circulation of a permanent inground system, dead zones quickly form in the corners and along the floor, allowing debris and organic matter to settle and decay. Managing this water requires constant vigilance and proactive maintenance rather than a set-it-and-forget-it attitude.

Filter Pump – Intex Krystal Clear Cartridge Pump

A filter pump is the heart of your pool’s circulation system, working constantly to pull suspended debris out of the water and keep sanitizing chemicals moving. Without active circulation, water stagnates, and even the most expensive chemicals cannot distribute evenly to do their jobs. The Intex Krystal Clear Cartridge Pump offers an affordable, highly efficient upgrade over the stock pumps that typically ship with temporary pools.

This pump stands out because of its integrated sediment flush valve and its reliable flow rate, which ensures your entire pool volume turns over multiple times a day. It uses easily replaceable Type A or C cartridges that trap fine particles down to the micron level, keeping the water visibly polished. Setup is straightforward, requiring only a simple hose connection and a GFCI-protected outlet for safe operation.

• Flow Rate Options: 330 GPH, 530 GPH, 1,000 GPH, and 1,500 GPH
• Cartridge Type: Type A or C (depending on pump size)
• Best For: Small to mid-sized metal frame and Easy Set pools up to 6,000 gallons
• Not Ideal For: Large permanent pools or systems requiring sand media backwashing

Before buying, verify your pool’s hose diameter, as larger models of this pump use 1.5-inch threaded fittings rather than the standard 1.25-inch clamp-on hoses found on basic splash pools. This unit is perfect for families upgrading their entry-level pool kits to achieve professional-grade filtration without a massive financial investment. It is not designed for heavy-duty commercial loads or pools exceeding 10,000 gallons.

Chlorine Shock – Clorox Pool&Spa Shock XtraBlue

When bather load increases or algae begins to take hold, regular chlorination is not enough to keep the water safe. You need a fast-acting shock treatment to destroy organic contaminants, sweat, lotion, and microscopic pathogens that cloud the water. Clorox Pool&Spa Shock XtraBlue is a highly concentrated formula designed to sanitize, clarify, and kill algae in one swift application.

This specific product is ideal for temporary pools because it features a built-in water clarifier and algae protection agent. It will not bleach your pool liner when used as directed, which is a common hazard with cheaper, industrial-grade calcium hypochlorite shocks. The granular formula dissolves rapidly, meaning you can get back to swimming much sooner than with traditional shock treatments.

• Active Ingredient: Sodium Dichloro-s-triazinetrione (99%)
• Treatment Ratio: 1 pound treats 12,000 gallons (scale down precisely for small pools)
• Best For: Rapid algae eradication and weekly water clarification
• Not Ideal For: Pools with extremely high stabilizer (cyanuric acid) levels

Because temporary pools have low water volume, you must pre-dissolve the granules in a bucket of pool water before pouring it around the perimeter to prevent localized liner damage. This shock is a must-have for anyone dealing with sudden water cloudiness or high-temperature summer stretches. It is not suitable for daily maintenance chlorination, as it will rapidly raise your stabilizer levels if overused.

Water Test Kit – AquaChek Select 7-Way Strips

You cannot manage what you do not measure, and guessing at your pool’s chemical balance is a quick recipe for skin irritation or green water. A reliable test kit gives you a real-time snapshot of your water’s chemistry so you can make precise adjustments. AquaChek Select 7-Way Strips provide clear accuracy in an easy-to-read, user-friendly format.

What makes this kit superior to basic paper strips is the included comparator chart and reusable test vial. It measures total chlorine, free chlorine, pH, total alkalinity, stabilizer (cyanuric acid), and total hardness in just 15 seconds. The color pads are highly distinct, reducing the guesswork that often leads to over-treating small pools with dangerous amounts of chemicals.

• Tests Performed: Total Chlorine, Free Chlorine, Bromine, pH, Total Alkalinity, Stabilizer, Total Hardness
• Count: 50 strips per bottle
• Best For: Quick, daily monitoring of temporary pool water health
• Not Ideal For: Pool owners who prefer liquid drop titration kits for lab-level precision

To get an accurate reading, always dip the strip elbow-deep into the water away from the return jets, rather than skimming the surface where chemicals can concentrate. This kit is perfect for busy pool owners who want fast, reliable results without dealing with messy liquid drop reagents. It is not the right choice if you suffer from color blindness or require hyper-precise chemical analysis for commercial-grade compliance.

Leaf Skimmer – Swimline Professional Heavy Duty

Windblown leaves, drowning bugs, and floating organic matter are constant enemies of pool water clarity. Leaving this debris floating on the surface allows it to break down and consume your active chlorine, leaving your pool vulnerable to algae blooms. The Swimline Professional Heavy Duty Leaf Skimmer is a rugged, fine-mesh net designed to lift debris out before it sinks to the bottom.

This skimmer features a heavy-duty aluminum frame wrapped in a protective plastic coating that will not scratch or tear delicate vinyl temporary pool liners. The deep, fine-mesh bag is engineered to scoop up everything from large oak leaves to tiny gnats and pollen particles. Its reinforced handle connection prevents the twisting and snapping that plagues cheap, all-plastic skimmer nets.

• Frame Material: Reinforced aluminum with non-marring plastic bumper
• Mesh Type: Extra-fine professional grade nylon
• Best For: Daily surface cleaning of bugs, leaves, and floating pollen
• Not Ideal For: Scooping heavy piles of wet debris from the very bottom of the pool floor

The skimmer requires a standard 1-1/4 inch telescoping pool pole, which is typically sold separately, so ensure you have one on hand. This tool is an absolute necessity for anyone whose yard is surrounded by trees or high winds. It is not meant for heavy-duty dredging of submerged muck; for that, a dedicated pool vacuum is required.

Floating Dispenser – GAME Derby Duck Chlorinator

Unlike permanent pools with inline chemical feeders, temporary pools require a continuous, slow release of sanitizer to maintain a steady chlorine baseline. A floating dispenser slowly dissolves chlorine tablets over several days, preventing dangerous spikes and drops in sanitation levels. The GAME Derby Duck Chlorinator combines rugged functionality with a playful, high-visibility design that adds personality to your backyard setup.

This dispenser features an adjustable chlorination rate ring at the base, allowing you to fine-tune how much water flows past the tablets. This control is critical for temporary pools, where standard dispensers often release too much chlorine into small water volumes. The heavy-duty plastic construction is highly resistant to UV rays and chemical degradation, ensuring it will not crack or fade over a long summer season.

• Capacity: Holds up to three 3-inch chlorine tablets
• Material: Heavy-duty, UV-resistant plastic
• Best For: Steady chlorination of small-to-medium above-ground pools
• Not Ideal For: Pools under 500 gallons, where even the lowest setting may over-chlorinate

Ensure you tie the dispenser off to a secure point on the pool frame if you find it constantly getting stuck in the skimmer basket or directly over the vinyl ladder, where concentrated chlorine could cause localized bleaching. This unit is perfect for pool owners who want a reliable, adjustable chlorinator that is easy to spot and retrieve. It is not recommended for shallow wading pools where small children might mistake it for a standard bath toy.

Handheld Vacuum – Intex Handheld Rechargeable Vacuum

Even the best filter pumps cannot pick up heavy dirt, sand, and pebbles that sink to the bottom of your pool. A handheld vacuum allows you to spot-clean the pool floor without wasting hundreds of gallons of water through a traditional backwash cycle. The Intex Handheld Rechargeable Vacuum is a self-contained, cordless solution that makes quick work of floor debris.

Powered by a rechargeable Ni-MH battery, this vacuum provides strong suction that easily lifts sand, pine needles, and small pebbles off the vinyl floor. It features an IPX8 waterproof rating and an automatic shut-off mechanism that triggers when the unit is out of the water to protect the motor. The interchangeable brush heads allow you to scrub stubborn spots while vacuuming, ensuring a pristine finish.

• Power Source: Rechargeable Ni-MH battery with USB charging cable
• Run Time: Up to 50 minutes of continuous suction per charge
• Best For: Cleaning sand, dirt, and light debris from small frame and inflatable pools
• Not Ideal For: Deep inground pools or clearing massive piles of heavy autumn leaves

Keep in mind that the unit must be fully submerged to operate, as the motor relies on the surrounding pool water for cooling. This vacuum is ideal for parents keeping beach sand and yard dirt out of their kids’ splash pools. It is not suitable for large-scale cleanup jobs following a major storm where the pool floor is entirely covered in thick mud.

Solar Cover – Intex Solar Round Pool Cover

Water evaporation is a major driver of chemical imbalance and heat loss in temporary pools. A solar cover acts as a physical barrier that traps heat, prevents water loss, and blocks falling debris from entering the pool when it is not in use. The Intex Solar Round Pool Cover uses thousands of tiny thermal bubbles to capture solar energy and transfer it directly into the water.

This cover is constructed from heavy-duty 120-micron material that stands up to constant sun exposure and chemical contact. By reducing evaporation by up to 95 percent, it preserves your chemical balance and significantly lowers your water utility bills over the course of the season. Its lightweight design makes it easy for a single person to roll up and store before a swim session.

• Material Thickness: 120-micron UV-resistant PVC
• Size Options: Available in 8ft, 10ft, 12ft, 15ft, and 18ft round configurations
• Best For: Retaining heat and reducing chemical evaporation in round above-ground pools
• Not Ideal For: Rectangular pools or as a safety cover designed to support weight

It is critical to remember that this is a solar blanket, not a safety cover; it will not support the weight of a child or pet, and adult supervision remains paramount. This cover is an exceptional choice for pool owners looking to extend their swimming season into the cooler spring and autumn months. It is not designed to withstand winter freeze conditions and must be stored indoors during the off-season.

Pool Algaecide – In The Swim Super Algaecide

Once algae takes root in a temporary pool, it can turn the water green and slick within 24 hours, requiring a complete drain and refill if left unchecked. An algaecide acts as a chemical shield, breaking down the outer membranes of algae spores so your chlorine can destroy them more effectively. In The Swim Super Algaecide is a non-foaming, copper-based formula that offers long-lasting protection.

This concentrated formula is highly effective because it contains copper triethanolamine complex, which prevents both green and mustard algae without causing the annoying foam that cheaper algaecides produce. It remains active in the water for up to two weeks, providing a reliable safety net during periods of extreme heat or when you are away on vacation.

• Active Ingredient: Copper Triethanolamine Complex (23.5%)
• Dosage Rate: 4 ounces per 10,000 gallons for weekly maintenance
• Best For: Preventing green, mustard, and black algae blooms in warm weather
• Not Ideal For: Pools with high metal content in their source water (can cause staining)

Because this is a copper-based product, precise dosing is vital; over-applying in small volumes can cause temporary staining on the vinyl liner or tint blond hair green. This algaecide is a smart investment for pool owners in hot, humid climates where algae is a constant threat. It is not recommended if you rely on municipal well water that already has high baseline iron or copper levels.

Pool Brush – Lalapool Heavy Duty Wall Brush

Even the strongest chemical regimen cannot destroy algae and bacteria that shield themselves behind a microscopic layer of biofilm on your pool walls. Physical brushing is required to disrupt this protective film, allowing your sanitizer to penetrate and kill the organisms. The Lalapool Heavy Duty Wall Brush features a wide, curved design that makes short work of scrubbing vinyl walls and floor seams.

The brush is built with heavy-duty ABS plastic and features curved ends that allow you to navigate tight corners without scratching or gouging the vinyl liner. The high-density nylon bristles are stiff enough to dislodge stubborn organic buildup but soft enough to protect the delicate printed patterns on temporary pool walls.

• Brush Width: 18 inches
• Bristle Material: Heavy-duty nylon
• Best For: Clearing biofilm, dirt, and early-stage algae from vinyl liners
• Not Ideal For: Heavy-duty wire brushing on rough concrete or plaster pools

This brush requires a standard telescoping pole with a V-clip connection to reach the center of larger pools safely. Use it at least once a week, focusing on the seam where the pool wall meets the floor, as this is the primary breeding ground for biofilm. It is not suitable for plaster or concrete pools that require harsh stainless-steel wire brushes.

How to Balance Chemical Levels in Small Water Volumes

Balancing the chemistry of a 1,000-gallon pool is fundamentally different from managing a 20,000-gallon inground system. Because the volume is so small, standard chemical dosing instructions—which often use increments of 10,000 gallons—must be scaled down with mathematical precision. Adding even a few ounces of chemical adjuster can swing the pH or chlorine levels from dangerously low to unsafely high in minutes.

To avoid chemical spikes, always calculate your exact pool volume using the formula diameter x diameter x depth x 5.9 for round pools. Once you have the exact gallon count, use a precise measuring cup or kitchen scale dedicated solely to pool chemicals. Never pour raw, concentrated chemicals directly into a small pool; always pre-dissolve dry chemicals in a bucket of clean pool water to ensure even distribution and prevent liner bleaching.

Keep a close eye on pH (the measure of acidity/alkalinity) and alkalinity (the pH buffer). In small volumes, heavy rain or sweat can cause the pH to crash rapidly, making the water highly corrosive to equipment and irritating to swimmer eyes. Test the water daily, make adjustments in micro-doses, and allow the filter pump to run for at least two hours before testing the water again.

Draining and Drying Your Pool to Prevent Winter Mold

When the swimming season draws to a close, proper decommissioning of your temporary pool is critical to preserving your investment for the following summer. Simply draining the water and tossing the folded vinyl liner into the garage is a guarantee that you will open a moldy, rotten mess next spring. Moisture trapped in the tight folds of stored PVC creates a perfect breeding ground for destructive black mold and mildew.

Start the process by using a submersible utility pump or a siphon hose to drain the water completely away from your home’s foundation and garden beds, as chlorinated water can damage landscaping. Once drained, use dry towels to wipe down every square inch of the liner, paying close attention to the seams and corner pockets where the support poles sit.

Leave the disassembled liner draped over lawn furniture in the direct sun for at least 24 to 48 hours to ensure absolute dryness. Before folding, dust the entire surface of the vinyl with talcum powder or cornstarch; this absorbs any residual micro-moisture and prevents the plastic from sticking to itself and tearing during winter storage. Store the folded liner in a heavy-duty, rodent-proof plastic bin in a climate-controlled space, away from extreme winter freezing.

Conclusion

Maintaining crystal-clear water in a temporary pool does not require a degree in chemistry, but it does demand consistency and the right set of tools. By establishing a routine of daily testing, weekly brushing, and proper circulation, you can prevent water issues before they even start. With these nine essential supplies in your backyard shed, you can confidently keep your pool safe, clean, and refreshing all summer long.
