Whether you’re new to pool ownership or upgrading your backyard oasis, understanding what to put in your pool after filling it is essential for maintaining optimal water quality, safety, and comfort for swimmers.
In this in-depth guide, we will walk you through everything you need to add to your above ground pool after it’s filled, including chemicals, equipment, accessories, and optional enhancements that can improve the overall pool experience. You’ll also learn key maintenance tips to keep your pool in top condition throughout the swimming season.
Understanding the Importance of Pool Maintenance After Filling
Filling your above ground pool is just the beginning. The quality of your pool water will directly affect not only the cleanliness and safety of your swimming environment but also the longevity of your pool structure and equipment. Water that is not properly balanced or sanitized can lead to algae growth, staining, equipment damage, and health hazards for swimmers.
To prevent such issues, it’s essential to take action immediately after filling your pool to:
- Balance the water chemistry.
- Sanitize the water to kill bacteria and pathogens.
- Introduce proper filtration and circulation systems.
- Enhance the overall swimming experience with accessories and comfort items.
Let’s break this down into actionable steps and items you should introduce to your pool after filling it.
Step 1: Test and Balance the Water Chemistry
Before adding any chemicals, it’s critical to test your pool water to determine its current chemistry values. Tap water can vary significantly in pH, alkalinity, hardness, and other factors depending on your local water supply.
The Essential Water Test Kit
You can use either a digital water testing kit or traditional test strips to analyze your pool water. These tools measure the following parameters:
| Parameter | Optimal Range | Description |
|---|---|---|
| pH Level | 7.2–7.6 | determines water acidity or basicity; affects swimmer comfort and sanitizer effectiveness. |
| Total Alkalinity (TA) | 80–120 ppm | measures the water’s ability to resist pH changes; stabilizes pH. |
| Calculated with the Langelier Saturation Index (LSI). |
By testing and correcting these levels before proceeding to sanitization, you’ll provide a stable environment for your chemicals to work more effectively and your pool equipment to function better.
How to Balance Water Chemistry
Based on your water test results:
- If the pH is too low, add pH increaser (sodium carbonate).
- If it’s too high, add pH decreaser (sodium bisulfate).
- If total alkalinity is too low, add an alkalinity booster (sodium bicarbonate).
- If calcium hardness is too low, add calcium chloride to protect against aggressive water that can etch pool surfaces.
Wait a few hours after adjusting any chemical levels and retest to confirm balance.
Step 2: Add a Sanitizer to Keep Water Clean
Once your water chemistry is stable, the next step is to disinfect the water to kill bacteria, algae spores, and other contaminants introduced during filling or from swimmers later.
Popular Pool Sanitizers and Their Uses
Each sanitizer works slightly differently, and your choice may depend on personal preference, local regulations, or water conditions.
Chlorine
Chlorine is the most widely used pool sanitizer. It comes in various forms:
Granular chlorine: dissolves quickly, ideal for shock treatments.
Tablets or sticks: dissolve slowly and are used in a floating dispenser or erosion feeder.
Chlorine liquid (sodium hypochlorite): same as household bleach but with higher concentration.
Bromine
Often used in spas but also effective in above ground pools, especially in warmer water conditions.
Pros: more stable in high temperatures than chlorine.
Cons: more expensive and doesn’t fade in sunlight.
Alternative Sanitizers
Other options include:
- Baqua: uses bromine chemistry for an alternative to traditional chlorine.
- Ionizers: use copper and silver ions to sanitize water, reducing the need for chemicals.
- Mineral systems: combine natural minerals and very low levels of chlorine for softened water.
Always introduce sanitizers based on the pool volume (measured in gallons), and double-check the instructions of the product for correct dosing.
Step 3: Start the Filtration System and Circulate the Water
Now that you’ve balanced the water and added the appropriate sanitizer, it’s time to start your pool filter to circulate and clean the water.
Types of Pool Filters
There are three main types of filters typically used in above ground pools:
| Filter Type | Pros | Cons |
|---|---|---|
| Cartridge Filters | Easy to clean, cost-effective, no backwashing needed | May need more frequent cleaning |
| Sand Filters | Durable, easy operation, effective for larger pools | Requires backwashing; slower filtration cycle |
| DE (Diatomaceous Earth) Filters | Most effective at removing small particles | Pricier, requires more maintenance, uses DE powder which is messy to handle |
Always ensure your filter is properly connected to the pump before use. Start your filter system on a daily schedule—typically 8–12 hours per day depending on the temperature and bather load—to maintain circulation and clean water.
Step 4: Alkalinity and pH Maintenance
Even after initial balancing, pool water chemistry fluctuates as swimmers introduce organic matter, and as UV rays affect sanitizer effectiveness. It’s important to maintain a regular check routine.
Shock the Pool Weekly
Shock treatments—also called oxidizing treatments—eliminate chloramines (combined chlorine), kill bacteria, and help maintain clarity.
There are two main types of pool shocks:
Chlorine-based shock: typically contains calcium hypochlorite; very effective but may increase calcium hardness.
Non-chlorine shock: often potassium monopersulfate; less irritating and swimmer-friendly, but does not disinfect.
Shocking the pool once a week (or after heavy use or rainfall) is highly recommended for long-term pool cleanliness and clarity.
Step 5: Optional Chemical Additives That Enhance Pool Conditions
Beyond the basics, there are optional treatments that can make your pool water more comfortable, extend equipment life, and reduce maintenance headaches.
Stabilizers (Cyanuric Acid)
Stabilizers help chlorine last longer in sunlight by reducing the rate at which UV rays degrade it. The ideal range is 30–50 ppm.
However, too much cyanuric acid can cause chlorine lock, which inhibits chlorine’s sanitizing power. Measure and add stabilizer carefully.
Clarifiers and Flocculants
These help with water clarity:
- Clarifiers: bind small particles together so the filter can trap them more effectively.
- Flocculants: make particles clump together and sink to the bottom for vacuuming.
Use clarifiers regularly, and flocculants if the water becomes cloudy or after heavy bather loads.
Algaecides
Even with sanitizer in place, algaecides can provide an extra line of defense against algae growth. Copper-based algaecides are most common and effective. Use sparingly to avoid over-coppering the water.
Step 6: Add Comfortable and Functional Accessories
Beyond chemical needs, certain accessories enhance safety, enjoyment, and comfort around your above ground pool.
Safety Equipment
Including the following safety gear can literally be life-saving:
- Life rings or throw ropes
- Non-slip pool steps or handrails
- Pool covers (safety covers for off-season or solar covers to maintain warmth)
- Rescue poles and first aid kits nearby
Comfort and Entertainment Accessories
These items improve your pool experience and can make your above ground pool feel like a resort:
Floats and loungers: inflatable pool toys or floating chairs help swimmers relax.
LED pool lights: especially useful if you plan to extend pool hours into the night.
Pool speakers: waterproof speakers that connect via Bluetooth let you enjoy music while swimming.
Swim platforms and ladders: make entering and exiting the pool easier.

What chemicals should I add to my above ground pool after filling it?
After filling your above ground pool, it’s crucial to add the right chemicals to maintain clean and safe water. The primary chemicals include chlorine, which sanitizes the water and kills bacteria, and pH balancers such as pH increaser or decreaser, which help maintain the correct acidity or alkalinity level. It’s also important to use a cyanuric acid stabilizer to protect chlorine from being depleted by sunlight. Depending on your water source, you may also need algaecide or a water clarifier to keep the pool clear and algae-free.
It’s best to start by testing the water using a pool test kit or strips. This will give you a baseline on the levels of chlorine (or alternative sanitizer), pH, alkalinity, and calcium. Based on the results, you can adjust the chemical amounts accordingly. Always follow the manufacturer’s instructions for safe handling and application. Adding chemicals gradually and allowing time for them to circulate ensures balanced water chemistry, preventing damage to the pool and ensuring a comfortable swimming experience.
How do I maintain proper water balance in my above ground pool?
Maintaining proper water balance in your above ground pool is essential for swimmer comfort and long-term pool health. Start by regularly checking the pH level, which should be kept between 7.2 and 7.8. Alkalinity acts as a buffer for pH and should ideally be between 80 and 120 ppm. Calcium hardness should also be monitored—it’s recommended to keep it around 200–400 ppm to prevent corrosion or scaling.
In addition to regular testing, you should maintain a consistent chlorine level of 1–3 ppm or use alternative sanitizers like bromine, saltwater systems, or mineral sanitizers. Automated chlorinators or floating dispensers can help keep sanitizer levels steady. Regular backwashing or cleaning of the filter, along with periodic shocking of the pool, helps eliminate contaminants and maintain clarity. Keeping a maintenance log can help you track changes and adjust chemical additions accordingly.
Can I add salt to an above ground pool with a saltwater system?
Yes, you can add salt to an above ground pool if it’s equipped with a saltwater chlorination system. Saltwater systems use salt to produce chlorine through electrolysis, offering a gentler and more consistent sanitization process. The recommended salt level typically ranges between 2,500 and 6,000 ppm, depending on your system’s specifications. It’s critical to use pool-grade salt, which is free of additives and impurities that might affect water clarity.
When adding salt, ensure the system is off and distribute it evenly across the pool while walking around the perimeter. Run the pump for at least 24 hours to fully dissolve the salt. Test the salinity with a saltwater testing kit to confirm the levels are in range. Always follow the manufacturer’s recommendations and maintain proper water balance, including pH and calcium, to ensure the longevity of both the pool and the chlorination system.
What pool accessories enhance safety and enjoyment for swimmers?
To enhance both safety and enjoyment in your above ground pool, consider investing in several key accessories. A sturdy pool ladder that meets safety standards is essential for easy entry and exit. Additionally, non-slip pool steps or a ramp may benefit children, seniors, or individuals with limited mobility. Pool alarms can also be installed to alert you when the water surface is disturbed, which improves safety for households with young children.
For comfort and enjoyment, consider floating fountains or LED lights that add ambiance and can extend swimming hours. Pool floats, toys, and inflatable loungers improve the fun factor, especially during family gatherings. Installing a pool cover when not in use increases safety by preventing unauthorized access and keeps debris out. These accessories not only make your pool more inviting but also contribute to peace of mind and a more enjoyable swimming experience.
How do I clean and maintain the pool filter after filling the pool?
After filling your above ground pool, your filter becomes the primary defense against debris and contaminants. The type of filter you have—sand, cartridge, or diatomaceous earth (DE)—determines the maintenance method. Initially, ensure the system is properly primed. You should run the filter for at least 8–10 hours daily to keep water circulation and filtration effective. Monitor the pressure gauge for sand and DE filters, as a significant increase indicates it’s time to backwash.
For cartridge filters, remove and clean the cartridge regularly using a hose or appropriate cleaning solution. All filters should be deep cleaned monthly or as needed. In addition, inspect all connections and O-rings for wear or leaks. Replacing worn parts and scheduling seasonal maintenance can extend the filter’s life and efficiency. Keeping your filter in good working condition is key to clear water and reduced chemical consumption.
What are the benefits of adding a pool heater or solar cover?
Adding a pool heater or solar cover to your above ground pool can significantly enhance your swimming experience. A heater allows you to enjoy the pool even during cooler seasons by maintaining a comfortable water temperature. There are various heater types—gas, electric heat pumps, or solar-powered—each with different efficiency levels and operating costs. Choosing the right system depends on your budget, pool size, and climate.
Solar covers, on the other hand, are a cost-effective and energy-efficient alternative to retain heat from the sun. They also reduce water evaporation, minimize chemical loss, and keep debris out. Using a solar blanket overnight or during non-use hours helps maintain consistent temperatures and reduces the workload on heaters. Both solutions work well together to extend your swim season, improve water quality, and reduce energy costs, making your pool more versatile and enjoyable year-round.
How often should I shock my above ground pool and why?
Shocking your above ground pool is a necessary step in keeping the water clean and balanced. Typically, you should perform this weekly, especially during periods of heavy use or hot weather. Pool shock is a high-dose oxidizer that eliminates bacteria, algae, and chloramines—compounds formed when chlorine reacts with contaminants like sweat and body oils. The frequency may vary depending on your pool’s size, the number of swimmers, and whether you use a saltwater system or alternative chlorine sources.
In addition to regular weekly shocking, it’s also important to shock after heavy rain, large gatherings, or if the water becomes cloudy or develops a strong chlorine odor. Always ensure the pool is empty of swimmers when shock is applied and wait until the levels return to normal before re-entry, usually after 8–12 hours. Liquid chlorine and calcium hypochlorite are common types of shock used, but some prefer non-chlorine alternatives. Monitoring oxidation-reduction potential (ORP) levels can help determine when a shock is needed, keeping your pool safe and clear.
