Find Out What Your Pool Water Needs
Pool water can appear clean while important chemical levels are outside their recommended ranges. Testing provides an accurate picture of your water before you make adjustments or purchase additional products.
A professional water test can help you:
- Maintain effective sanitizer levels
- Improve swimmer comfort
- Prevent algae and cloudiness
- Reduce staining and scale
- Protect pool surfaces and equipment
- Prepare your pool for opening or closing
- Troubleshoot water that is difficult to maintain
Whether you are performing routine maintenance or trying to correct a specific problem, accurate readings give you a reliable place to start.
What Does a Pool Water Test Check?
Several factors work together to influence pool-water quality. When one level changes, it can affect sanitizer performance, water clarity and the condition of your pool equipment.
Depending on your pool and the issue you are experiencing, testing may include:
- Free chlorine: The active chlorine available to sanitize the water
- Total chlorine: The overall amount of chlorine in the pool
- pH: The acidity or alkalinity of the water
- Total alkalinity: Helps prevent rapid changes in pH
- Calcium hardness: Influences scaling, corrosion and surface protection
- Cyanuric acid: Helps protect chlorine from sunlight
- Salt level: Used to evaluate saltwater-pool operation
- Phosphates: May contribute to algae growth when present at high levels
- Metals: Iron and copper may cause staining or discolouration
- Overall water balance: Shows how the different readings are interacting
Once the test is complete, our team will review the readings with you and identify which areas may require attention.
What to Bring for Your Water Test
Collect your sample in a clean bottle or water-sample container. Take the water from approximately elbow depth and avoid collecting it directly beside a return jet, skimmer or pool step.
For the most useful assessment:
- Collect the sample on the day you plan to visit
- Keep it out of direct sunlight
- Do not leave it in a hot vehicle
- Know the approximate size or volume of your pool
- Tell us whether it is chlorine or saltwater
- Make a note of any products recently added
- Mention when the pool was last shocked
- Describe any changes in colour, clarity or smell
Photos can also be helpful when you are dealing with algae, unusual water colour, poor circulation or a possible equipment issue. Consider taking pictures of the pool, pump, filter, heater or salt system before visiting.
How In-Store Water Testing Works
- Collect Your Sample
Use a clean container and take the sample from below the surface, away from concentrated water-flow areas.
- Visit Our Kelowna Store
Bring the sample to 151 Adams Road, Unit 3. No complicated preparation is required.
- Have the Water Analyzed
We will check the relevant chemical levels and consider any symptoms you have noticed.
- Review Your Results
Our team will explain which readings are within range, which need attention and what may be contributing to the problem.
- Follow a Clear Treatment Plan
When adjustments are required, we can help you select suitable products and explain the order in which they should be used.
Some treatments require time to circulate before the water can be accurately retested. We will let you know whether another sample is recommended.
Pool Chemicals Based on Your Test Results
Pool chemicals should solve a demonstrated need rather than be added through trial and error. Your test results allow us to narrow down the problem and recommend a more targeted approach.
Trevi Pools & Spas Kelowna carries products for:
- Routine chlorine and sanitizer maintenance
- Shocking and oxidizing the water
- Raising or lowering pH
- Adjusting total alkalinity
- Correcting calcium hardness
- Increasing stabilizer levels
- Preventing or treating algae
- Improving water clarity
- Managing phosphates
- Controlling stains and scale
- Maintaining saltwater systems
- Opening and winterizing pools
The correct treatment depends on the complete water profile. For example, cloudy water is not always caused by low chlorine, and a strong chlorine smell does not necessarily mean that too much chlorine has been added.
Testing helps distinguish between chemical imbalance, sanitizer demand, circulation problems and filtration issues.

Help With Cloudy, Green or Discoloured Water
Problem water can develop after hot weather, heavy swimming, rainfall, equipment problems or an interruption in regular maintenance.
We can help investigate symptoms such as:
- Cloudy or dull water
- Green water
- Visible algae
- Water that remains cloudy after shocking
- Strong chlorine odours
- Eye or skin irritation
- Foamy water
- Staining or unusual discolouration
- Scale around the pool or equipment
- Rapid loss of chlorine
- Water that is consistently difficult to balance
Chemical treatment may be part of the solution, but circulation and filtration should also be considered. If your pump is not moving enough water or your filter is not operating effectively, the pool may remain cloudy even when the chemical readings have improved.
Bring photos of the pool and equipment if you suspect the problem is not solely related to water chemistry.

Saltwater Pool Testing in Kelowna
A saltwater system produces chlorine, but it does not automatically control every aspect of pool-water balance. Saltwater pools still require monitoring throughout the swimming season.
Testing may include:
- Salt concentration
- Free and total chlorine
- pH
- Total alkalinity
- Calcium hardness
- Cyanuric acid
- Phosphates or metals when relevant
Saltwater pools can experience elevated pH and calcium buildup, which may contribute to scale on the salt cell. If the cell becomes coated, its ability to generate chlorine can decline.
Regular testing can help protect the salt system while keeping the water comfortable and easier to maintain. Trevi Kelowna also carries pool salt, salt-cell cleaner and supporting water-care products.
How Often Should Pool Water Be Tested?
Home testing should be performed regularly during the swimming season. Professional testing is useful for routine confirmation, seasonal preparation and any time the water begins to look or feel different.
Consider testing more frequently:
- During very hot weather
- When the pool is used daily
- Before or after a pool party
- Following heavy rain or strong winds
- After topping up the pool
- After adding corrective chemicals
- When chlorine levels change unexpectedly
- When swimmers experience irritation
- When the water becomes cloudy or discoloured
- During spring opening or fall closing
The frequency will depend on pool use, weather, water temperature and the type of sanitation system you operate.
Pool Care During Kelowna Summers
Kelowna’s summer heat, intense sunlight and dry conditions can place additional demand on pool water.
Sunlight can break down chlorine, while warmer water and frequent swimming can increase sanitizer consumption. Wind may also introduce dust, pollen, leaves, ash or other debris that affects clarity and filtration.
Pay particular attention to your water:
- During extended periods of high temperatures
- After weekends of heavy pool use
- Following rain or windy weather
- When wildfire smoke or airborne debris is present
- After adding a significant amount of fresh water
- When using a pool heater or cover regularly
Small, timely corrections are generally easier to manage than waiting until the pool becomes cloudy or algae begins to grow.
Water Testing for Pool Opening and Closing
Seasonal water testing helps you begin and end the swimming season with a clearer understanding of your pool’s condition.
Pool Water Testing for Spring Opening
Water chemistry can shift significantly over the winter. Once the pool has been uncovered, filled to its operating level and circulation has resumed, testing can reveal which adjustments are necessary.
Your opening plan may include:
- Restoring sanitizer levels
- Correcting pH and alkalinity
- Adjusting calcium hardness
- Adding stabilizer
- Treating algae
- Improving clarity
- Balancing a saltwater pool
Testing prevents you from automatically adding a full range of products when only certain adjustments may be required.
Pool Water Testing Before Winter Closing
Before winterizing, the water should be balanced to reduce the risk of staining, scale and surface damage while the pool is closed.
A fall test can help determine whether the pool requires:
- pH or alkalinity adjustment
- Shock or sanitizer
- Winter algaecide
- Stain-and-scale control
- Saltwater balancing
- Other closing products
Complete the test with enough time to circulate any necessary treatments before the pool is shut down.
