Steps to Take Before Opening Your Inground Pool

Before touching a single plug or valve, clear the surrounding deck of leaves, dirt, and branches to prevent wind from blowing debris right into the exposed water. Ensure that the water level underneath the pool cover is high enough—ideally halfway up the skimmer mouth—before starting up the filtration system. Trying to run the pump with low water can pull air into the system, causing the pump to run dry and burn out the motor.

Inspect all pool equipment, including the pump, filter, heater, and salt cell, for any signs of freeze damage or cracked housing from the winter. Reinstall all drain plugs on the pump basket, filter tank, and heater, using fresh plumber’s tape on the threads to guarantee an airtight seal. Once the mechanical components are inspected, clear any standing water and heavy debris off the pool cover using specialized tools to prevent it from dumping into the clean pool below.

Cover Pump – Little Giant APCP-1700 Pool Pump

Removing thousands of gallons of stagnant rainwater and melted snow from a solid winter cover is the first major hurdle of spring. A high-quality cover pump prevents this heavy, debris-filled water from slipping into the clean pool when the cover is removed. It also relieves stress on the cover straps, protecting the pool’s coping and anchor points from structural damage.

The Little Giant APCP-1700 is built specifically to handle this demanding task without constant supervision. This pump features an automatic float switch that activates when water reaches two inches and shuts off when the surface is clear, preventing dry-running.

• Flow Rate: Up to 1,745 gallons per hour
• Power Cord Length: 25 feet
• Connection Type: Fits a standard 3/4-inch garden hose
• Intake Protection: Removable intake screen for easy cleaning

A primary consideration when using this pump is keeping the intake screen clear of large leaves and twigs, which can clog the unit and restrict flow. It must be plugged into a grounded GFCI outlet for electrical safety, and using a heavy-duty, kink-free garden hose will ensure maximum water flow.

This pump is a must-have for pool owners with solid safety covers or traditional tarp-and-water-bag covers. It is not necessary for pool owners who utilize tight mesh safety covers, as these covers allow water to drain naturally into the pool below.

Pool Brush – SweepEase 18-Inch Stainless Steel

Algae, calcium scale, and organic stains cling to pool walls over the winter, hardening in the cold water. A heavy-duty pool brush is essential to break these contaminants loose so the pool filter can trap them. Regular brushing also distributes startup chemicals evenly, preventing concentrated shock from bleaching or damaging pool finishes.

The SweepEase 18-Inch Stainless Steel Brush stands out because of its patented spoiler design, which uses water flow to press the brush head firmly against the pool wall as it is pushed down. This eliminates the need for intense physical strain, allowing the user to clean walls with one hand.

• Bristle Material: 100% AISI 304 Marine Grade Stainless Steel
• Width: 18 inches
• Handle Connection: Quick-release V-clip fits standard poles
• Build: Heavy-duty reinforced aluminum back

The stainless steel bristles are extremely aggressive on stubborn algae, but they require strict compatibility awareness. This brush should never be used on vinyl liners, fiberglass pools, or painted surfaces, as the metal bristles will scratch and destroy these materials.

This tool is perfect for owners of concrete, gunite, or plaster pools who need to tackle tough winter scale and black algae. It is entirely unsuitable for vinyl or fiberglass pools, which require soft nylon or poly bristles instead.

Water Test Kit – Taylor Service Complete K-2006

Relying on cheap test strips or guessing chemical dosages at startup is a recipe for chemical lock and cloudy water. Accurate water testing is the foundation of a successful pool opening, allowing for precise adjustments to pH, alkalinity, and sanitizer levels. Without precise numbers, pool owners risk wasting money on excess chemicals or under-treating dangerous pathogens.

The Taylor Service Complete K-2006 uses liquid reagents and a titration method that offers unmatched accuracy compared to retail test strips. Its FAS-DPD chlorine test measures free and combined chlorine levels directly down to 0.2 ppm, removing any subjective color-matching guesswork.

• Testing Parameters: Free/Combined Chlorine, pH, Acid/Base Demand, Total Alkalinity, Calcium Hardness, and Cyanuric Acid
• Reagent Size: 2-ounce bottles (Service size)
• Included Accessories: Water sample comparator, waterproof chemistry guide, and dosage charts

Reagents degrade when exposed to extreme heat or freezing temperatures, so this kit must be stored indoors in a cool, dark place. There is a slight learning curve to counting drops and watching for distinct color changes, but the included instruction card makes the process straightforward.

This kit is an indispensable investment for any pool owner committed to maintaining their own water chemistry and saving money on pool store diagnostics. It is not the right choice for those who prefer convenience over accuracy and plan to rely solely on local pool store testing.

Pool Shock – Clorox Pool&Spa Shock XtraBlue

A long winter of stagnant water allows bacteria and microscopic algae spores to colonize the pool, even if the water looks clear. Shocking the pool at startup sanitizes the water, breaks down combined chlorine (chloramines), and oxidizes organic bather waste. This high-dose sanitation is non-negotiable for establishing a safe baseline for the swim season.

The Clorox Pool&Spa Shock XtraBlue formula is highly effective because it performs multiple functions in a single application. Aside from sanitizing, it contains integrated clarifiers that clump micro-debris together and algaecides that target stubborn spores.

• Active Ingredient: Sodium Dichloro-s-triazinetrione (Dichlor)
• Form: Fast-dissolving granules
• Additional Benefits: Algae-killing crystals, water clarifiers, and scale inhibitors
• Dosage: 1 pound treats 12,000 gallons

Because this shock is stabilized with cyanuric acid, it will slowly raise the pool’s stabilizer levels over time. It is best applied at dusk to prevent the sun’s UV rays from burning off the active chlorine before it can work.

This shock is ideal for traditional chlorine and saltwater pools that need a fast, multi-action boost to jumpstart water clarity. It is not recommended for pools that already have excessively high cyanuric acid levels, which would require unstabilized liquid chlorine instead.

Algaecide – PoolRx Blue Swimming Pool Unit

Even after shocking, microscopic algae spores can linger in hard-to-reach areas like light niches, step seams, and plumbing lines. An effective algaecide provides a secondary layer of defense, destroying the cellular structure of algae and preventing future blooms as the water warms up. This is especially critical during the unpredictable temperature swings of early spring.

The PoolRx Blue Swimming Pool Unit utilizes a patented mineral formulation of chelated copper to continuously sanitize the water. Unlike traditional liquid algaecides that must be dosed weekly, this unit is placed directly into the pump basket or skimmer and lasts for up to six months.

• Active Ingredients: Copper Sulfate Pentahydrate (chelating agent)
• Lifespan: Active for up to 6 months of continuous protection
• Pool Size Compatibility: 7,500 to 20,000 gallons
• Filter Compatibility: Safe for all filter types (sand, cartridge, DE)

The mineral unit must be replaced every spring, and the pool’s pH must be kept within the standard 7.2 to 7.6 range to prevent the copper from precipitating out of solution and staining the pool finish. If the pool volume exceeds 20,000 gallons, multiple units or additional booster packs will be required.

This product is perfect for pool owners seeking low-maintenance, season-long protection against green, yellow, and black algae. It is not suitable for pools filled with source water that already contains high natural concentrations of copper or heavy metals.

Skimmer Net – ProTuff 18-Inch Pool Rake

Spring wind and rain dump massive amounts of heavy organic debris, like leaves, seed pods, and twigs, onto the pool floor and surface. Standard plastic skimmers often crack under the weight of wet debris, forcing pool owners to make multiple shallow passes. A commercial-grade pool rake allows for deep scoops to clear the pool floor quickly before organic matter decays and stains the plaster.

The ProTuff 18-Inch Pool Rake features a heavy-duty aluminum frame wrapped in a protective plastic coating that prevents scraping on pool walls. The deep, double-stitched nylon mesh bag is designed to scoop large volumes of heavy debris without tearing.

• Frame Material: Anodized aluminum with protective resin coating
• Net Material: Heavy-duty, chemical-resistant nylon mesh
• Size: 18-inch wide mouth
• Warranty: Lifetime replacement guarantee

The deep pocket design creates drag when pulled through the water, requiring some physical effort when fully loaded with wet leaves. To use this rake, a high-quality aluminum telescopic pole must be purchased separately.

This tool is a must-have for properties with heavy tree cover or those dealing with deep leaf piles at the bottom of the pool. It is overkill for screened-in pools or manicured yards where only minimal surface skimming is required.

O-Ring Lubricant – Jack’s Formula 327 Multilube

As pool equipment is reassembled in the spring, dry or cracked rubber O-rings can cause immediate suction-side air leaks or pressurized water leaks. Lubricating these seals ensures an airtight fit, protects the rubber from chemical degradation, and makes future equipment servicing much easier. Neglecting this simple step can lead to pump priming issues and air bubbles in the pool returns.

Jack’s Formula 327 Multilube is a professional-grade, silicone-based lubricant designed specifically for pool equipment. Unlike petroleum-based lubricants, which break down rubber and cause O-rings to stretch or tear, this formula preserves the integrity of rubber seals.

• Base Material: 100% silicone formula
• Water Resistance: High-viscosity, waterproof, and non-melting
• Application Areas: Pump lid O-rings, filter seals, chlorinator threads, and push-pull valves

Before applying the lubricant, clean both the O-ring and its mating groove with a microfiber cloth to remove old grit and debris. Apply a thin, even coat; excessive lubrication can attract dirt and cause sealing issues over time.

This lubricant is an absolute necessity for every pool owner reassembling pump baskets, canister filters, or inline chlorinators. It is not suitable for applications requiring temporary, water-soluble lubricants, as this silicone formula is designed to endure.

Metal Sequesterer – Natural Chemistry Metal Free

Source water often contains dissolved minerals like iron, copper, and manganese, which can oxidize and discolor the water when high doses of chlorine shock are added. This oxidation can leave stubborn brown, green, or purple stains on the pool walls and steps. A metal sequesterer deactivates these minerals, keeping them in suspension so they cannot bond to pool surfaces.

Natural Chemistry Metal Free is highly effective because it uses a natural, phosphorus-free chelating agent. Traditional metal removers often contain phosphates, which serve as direct food for algae and can trigger massive blooms during spring startup.

• Active Ingredient: Natural, non-phosphorus chelating agents
• Dosing: 1 liter treats up to 20,000 gallons
• Compatibility: Works with all sanitizer types and pool surfaces

This treatment must be added directly to the pool water before the initial shock dose is introduced, as shocking will immediately oxidize any unprotected metals. It does not actually remove the metals from the water; it simply deactivates them, meaning periodic maintenance doses may be required if well water is used for top-offs.

This product is highly recommended for pool owners who fill their pools with well water or municipal water known to contain trace metals. It is unnecessary for pool owners with verified metal-free municipal source water.

Water Clarifier – Robarb Super Blue Clarifier

Even with a perfectly balanced pool and active filtration, microscopic particles like pollen, dust, and dead algae can remain suspended in the water, causing a stubborn, cloudy haze. These particles are too small to be trapped by standard filter media and will continue to bypass the system. A water clarifier binds these tiny particles together into larger clumps that the pool filter can easily capture.

Robarb Super Blue Clarifier is a highly concentrated formula that works fast to restore polished clarity to pool water. It does not affect the pool’s pH balance and is formulated to resist clogging the filter media.

• Concentration: Only 1 ounce treats 5,000 gallons
• Filter Compatibility: Safe for cartridge, sand, and DE filters
• Form: Liquid polymer

Strict adherence to the dosage instructions is critical, as adding too much clarifier can cause the polymer to act as a dispersant, making the water cloudier than before. Ensure the pool filter runs continuously for 24 hours after application to thoroughly clear the bound particles.

This is an excellent tool for pool owners who want to accelerate the clearing process after a heavy algae treatment or pollen storm. It is not a remedy for underlying water balance issues or inadequate daily filtration runtimes.

Filter Cleaner – BioGuard Strip Kwik Cleaner

During the winter, oil, grease, scale, and organic debris accumulate on the filter media, creating a compacted layer that restricts water flow and lowers filtration efficiency. Simply backwashing a sand filter or rinsing a cartridge with a hose will not remove these stubborn oils. A dedicated chemical filter cleaner breaks down these deposits, restoring optimal flow and extending the lifespan of the filter media.

BioGuard Strip Kwik Cleaner features a patented, heavy-duty formula designed specifically to strip away body oils, cosmetics, and environmental grease from filter elements. It improves overall filtration efficiency, allowing the system to clear spring water much faster.

• Target Contaminants: Oils, grease, organic waste, and light scale
• Application Method: Spray-on for cartridges; pour-in for sand and DE filters
• Compatibility: Safe for all filter types

The cleaning process requires soaking the filter media, meaning the pool system will need to be shut down for several hours during the treatment. Users must wear protective gloves and eyewear, and rinse the filter elements thoroughly with clean water before restarting the system.

This product is highly recommended for pool owners looking to start the swim season with maximum filtration capacity and lower system pressure. It is not necessary if the pool filter media (sand or cartridges) was completely replaced at the end of the previous season.

How to Balance Pool Chemistry After Opening

Once the physical debris is cleared and the filtration system is running smoothly, chemical balancing can begin. This process must follow a strict order of operations; attempting to adjust chemicals out of sequence can result in neutralized treatments and wasted chemistry. Always start by testing and adjusting the Total Alkalinity (TA), which acts as a buffer to stabilize the pH.

After securing the TA between 80 and 120 ppm, adjust the pH levels to fall within the ideal range of 7.2 to 7.6. Maintaining this range ensures that the chlorine shock added next remains highly active and will not irritate swimmers’ skin or eyes. Once the pH is locked in, introduce the shock treatment at dusk to sanitize the water and oxidize any remaining organic compounds.

Run the filtration system continuously for 24 to 48 hours to circulate the chemicals and capture suspended debris. Keep a close eye on the filter’s pressure gauge during this period, as dead algae and pollen will clog the filter quickly, requiring frequent backwashing or cartridge rinsing to maintain optimal water flow.

Conclusion

Opening an inground pool for the spring season does not have to be an overwhelming chore if approached with the proper strategy and equipment. By utilizing specialized maintenance tools and high-quality chemical treatments, pool owners can protect their pool components and achieve crystal-clear swim conditions quickly. Armed with this essential gear list, the path to a worry-free, refreshing summer of backyard water recreation is clear.
