Maintenance of a new above-ground pool: the complete guide to getting started properly

A new pool should mean enjoyment, not stress. The first few days are nevertheless important: this is when you establish proper circulation, good water balance, and a simple routine that will make the rest of the season easier.

This guide brings together the essential steps to follow after installation: filling, water testing, balancing, sanitization, filtration, chlorine or salt maintenance, filter cleaning, the first few weeks, and seasonal routines.

Welcome to Piscine Hippocampe

A guide designed to support you through your first season

Thank you for entrusting us with your project. The goal of this guide is to give you clear reference points to understand your pool, establish good habits from the start, and know when to ask for help. A pool that is started up properly is generally much easier to maintain throughout the summer.

The first 7 steps

Your post-installation roadmap

1. Fill and circulate

Bring the water to the proper level and check the pump, return lines, and for leaks.

2. Have the water tested

Avoid making blind adjustments on the first day.

3. Balance the water

Start with alkalinity, then pH, followed by the other parameters.

4. Start sanitization

With chlorine or a salt system, depending on your setup.

5. Schedule filtration

Depending on the volume, flow rate, temperature, and usage.

6. Monitor more closely during the first week

New water can change quickly after the initial adjustments.

7. Move to a regular routine

Once the water is stable, a few simple checks are all that is needed.

Maintenance of a new above-ground pool

Step 1

Put the pool into circulation properly

When the pool is filled to the proper level, start the pump and check that the water is circulating normally through the return lines. Inspect the unions, pump lid, valves, and fittings for any leaks or air intake.

Take advantage of this first start-up to note the filter pressure when it is clean. This value becomes your reference for knowing later when the filter starts to get dirty.

Step 2

Test and balance the water as soon as the pool is filled

Even municipal water is not automatically balanced for a pool. Parameters can vary from one municipality to another, and some may change after filling.

The proper correction order is generally: alkalinity → pH → hardness/stabilizer according to the analysis → sanitization. To understand this logic in detail, consult our complete guide to water balancing.

Which parameters should you monitor?

Exact targets depend on the type of treatment, liner, equipment, and manufacturers’ recommendations. The most important parameters to check are:

Alkalinity

Helps stabilize pH.

pH

Affects the comfort and effectiveness of the disinfectant.

Free chlorine

Indicates the available disinfectant.

Stabilizer

Protects chlorine from UV rays when used at the proper level.

Calcium hardness

Part of the overall water balance.

Salt, if applicable

The target depends on the installed system.

Our advice for a new pool: test before adding anything

Bring a sample to the Piscine Hippocampe laboratory after circulation has begun. This establishes an accurate baseline before making multiple adjustments and reduces the risk of overdosing or unnecessary purchases.

Step 3

Choose your disinfection method: chlorine or salt

A saltwater pool is still a chlorine-disinfected pool: the generator converts the salt dissolved in the water into chlorine. The main difference lies in how the chlorine is produced and managed.

Chlorine pool

Structured routine with Day & Night

For owners who use traditional chlorine disinfection, we highlight the Solei & Luna Day & Night program. It helps organize maintenance around complementary products rather than waiting for the water to develop a problem.

Saltwater pool

Automated chlorine production

With a system like the MOOV MiniSalt MC50MINI, chlorine production is automated. The required salt level depends on the model and selected mode; always follow the recommendations for the installed system.

Featured technology

Solei & Luna Day & Night to simplify the first season

A new pool is the best time to establish a simple routine from the start. The Day & Night program combines Solei, a sun-activated oxidizer, and Luna, a mineral treatment used in the weekly routine.

The goal is not to replace water testing or disinfection, but to add a regular structure to maintenance.

Step 4

Understanding salt systems without complicating things

A salt chlorinator does not eliminate maintenance: it automates chlorine production. You still need to monitor the pH, free chlorine, cell condition, and salt concentration.

Modern systems such as MiniSalt MC50MINI or JustSalt MC50JUST can operate with different concentrations depending on their configuration. Check your model's manual rather than automatically applying a single ppm target.

Once the water is balanced and the salt has completely dissolved, gradually adjust the generator's output. The correct setting is the one that keeps your chlorine level within the target range despite the temperature and actual usage.

When should you increase or reduce the generator's output?

Increase gradually

During hot weather, high pool usage, or if the chlorine becomes insufficient.

Reduce gradually

When the water is cold, the pool is lightly used, or the chlorine remains too high.

Don't adjust blindly

Test the water after making adjustments to understand the actual effect.

Step 5

Filtration: the heart of maintenance

Chemistry cannot compensate for poor circulation. The filter must remove particles and contaminants while the pump circulates the water throughout the pool.

The daily filtration time depends on the pool volume, the pump's actual flow rate, the filter type, the temperature, and pool usage. Therefore, there is no need to use a fixed rule of 10, 12, or 24 hours for all pools.

Start with a reasonable schedule, observe the water clarity, and adjust according to conditions. During a heat wave or after a day of intensive swimming, longer filtration may be helpful.

Improved filtration

Silica sand or AFM® NG?

Both can be used in a compatible filter, but they are not intended to deliver the same level of performance. Silica sand is the traditional solution. Dryden Aqua AFM® NG is an activated filter medium designed to improve filtration quality and limit biological fouling of the medium.

For a new installation, this is an option to consider if you want to maximize filter performance from the start.

When should I backwash?

Primarily use the reference pressure of your clean filter, the flow at the returns, and the manufacturer’s recommendations. When the pressure increases significantly and the flow decreases, backwashing may be necessary.

Avoid backwashing unnecessarily often: a filter needs time to work properly, and each backwash discharges treated water.

Step 6

The first week: monitor more closely, then simplify

The first few days help you understand how your water and equipment behave. During this period, test more often than you will later in the season.

Days 1–2

Check circulation, leaks, filter pressure, and the initial water parameters.

Days 3–4

Recheck pH and sanitation after the initial adjustments.

Days 5–7

Adjust filtration or chlorine production according to the temperature and usage.

After one week

If the water is stable, switch to a simpler weekly routine.

Seasonal routine

The ideal routine for an above-ground pool

Several times a week

Check the sanitizer and pH, especially in hot weather.

Every week

Brush less-circulated areas, empty the baskets, and inspect the filter.

After significant rainfall

Check the water level, chlorine, pH, and clarity.

After heavy swimming

Test the chlorine and temporarily increase filtration if necessary.

Periodically

Have a complete laboratory analysis done to detect parameters that drift slowly.

Mistakes to avoid

Common mistakes made by new pool owners

Adding several products without testing

Every adjustment affects the rest of the balance.

Set the salt generator too high right from the start

Start reasonably and adjust based on testing.

Relying only on the water’s clarity

Clear water can still be poorly balanced.

Neglecting filtration

Perfect chemistry does not replace good circulation.

Backwashing too often

Use pressure and flow rate as reference points.

Waiting for the water to turn green

A preventive routine requires much less effort.

When should I return to the Piscine Hippocampe laboratory?

For a new pool, we recommend a complete analysis at startup, followed by monitoring when the parameters are difficult to stabilize, after a major correction, or when a problem persists despite good filtration.

Bring a representative sample from your pool and, if possible, tell us your treatment method, pool volume, and the last products added.

FAQ

Frequently asked questions about a new above-ground pool

How long should I filter an above-ground pool?

The duration depends on the volume, pump flow rate, filter, temperature, and usage. Adjust the filtration time according to the conditions rather than following a fixed rule.

How often should I test the water during the first week?

Test more often during the first few days, especially after the initial adjustments. Once the water is stable, you can space out the checks.

Is a salt pool chlorine-free?

No. The generator converts dissolved salt into chlorine. Disinfection therefore remains chlorine-based.

How much salt should be added?

This depends on the generator’s volume and model. Some modern systems can operate at different concentrations. Always use the target specified by your system’s manufacturer.

When should I backwash?

When the pressure increases significantly compared with the pressure of a clean filter or when the flow rate decreases. Also consult the filter manual.

Which filter media should I choose?

Silica sand remains a traditional option. AFM® NG is an activated alternative designed to improve filtration performance in compatible filters.

Should I use Day & Night if my pool is a salt pool?

The Day & Night program is presented here primarily as a routine for pools maintained with chlorine. A salt pool already has an automated chlorine production system and should follow the routine suited to its generator.
