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 or Spa 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 a Pool Water Test
For a pool: Collect the sample from approximately elbow depth, away from returns, skimmers, steps and areas where chemicals were recently added.
For a spa: Collect the sample from the middle of the spa, below the surface and away from jets. Turn the jets off first and use a clean container.
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
1. Bring Us a Fresh Water Sample
Collect a fresh sample from your pool, spa or hot tub in a clean container and bring it to our Kelowna store. Follow the sample instructions above to help us obtain the most reliable reading.
2. We Test Your Water with WaterLink Spin Touch
Trevi Pools & Spas Kelowna uses the professional WaterLink Spin Touch system to test pool and spa water. The photometer uses a sealed SpinDisk containing precise amounts of reagent to automatically test the important water levels, helping provide fast, consistent and highly accurate results.
3. We Explain Your Results
Our team will review the results with you in straightforward language. We’ll explain which levels are properly balanced, which ones need attention and what may be causing problems such as cloudy water, algae, foam, odours or scale.
4. You Receive a Clear Treatment Plan
We’ll help you determine which products to use, how much to add, the correct order for adding them and when to bring back another sample for retesting.
Complimentry Spa and Hot Tub Water Testing
Spa water can change quickly because of its warm temperature, smaller water volume and frequent use. Sanitizer and pH levels may shift faster than they do in a swimming pool, even when the water still looks clear.
Bring a fresh spa or hot tub water sample to Trevi Pools & Spas Kelowna for in-store testing with our WaterLink Spin Touch system. We can test the important water levels, explain the results and help you correct issues such as cloudy water, foam, odours, scale or difficulty maintaining the proper sanitizer level.
Depending on your spa system, testing may include chlorine or bromine, pH, total alkalinity, calcium hardness and overall water balance.
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 for Cloudy, Green, or Problem Pool 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.
Cloudy, Green, or Unbalanced Pool Water?
Start with accurate readings before adding another treatment. Visit our Kelowna store with a fresh sample and any photos that may help us assess the situation.
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 You Test Your Pool Water?
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
Pool water testing is one of the best first steps when opening your pool in the spring or closing it in the fall. Before you add opening or closing chemicals, a water test helps you understand what your pool actually needs.
At Trevi Pools & Spas Kelowna, we offer in-store pool water testing to help Okanagan pool owners start and end the season with properly balanced water.
Pool Water Testing for Spring Opening
After winter, your pool water may be out of balance even if it looks fairly clear. Low chlorine, high pH, low alkalinity, algae, debris, or poor circulation can all affect your spring start-up.
When opening your pool, a water test can help determine whether you need:
- Pool shock
- Chlorine or sanitizer
- pH increaser or reducer
- Alkalinity increaser
- Calcium hardness adjustment
- Stabilizer
- Algaecide
- Clarifier
- Stain and scale control
- Saltwater pool products
- Filter or circulation support
Testing first helps you avoid adding the wrong products or using more chemicals than necessary. Once we see your results, our team can recommend the right opening chemicals and explain the best order to add them.
Pool Water Testing for Winter Closing
Before closing your pool for the season, it is important to balance the water properly. Closing with unbalanced water can contribute to staining, scale, algae growth, cloudy water, or equipment issues over the winter.
A fall water test can help you prepare your pool for closing by checking key levels like chlorine, pH, alkalinity, calcium hardness, stabilizer, salt level, and overall water balance.
Depending on your results, we can help you choose:
- Pool closing chemicals
- Winter algaecide
- Shock
- Stain and scale control
- pH and alkalinity products
- Saltwater balancing products
- Winterizing accessories
Whether you are opening your pool for the first swim of the year or getting ready to close it for the Okanagan winter, bring in a fresh water sample before adding chemicals. Our Kelowna team can test your water, explain your results, and help you choose the right products for the season.
