General Pool Maintenance FAQs
How often should I clean my pool?
To keep your pool clean and safe, follow this routine:
•Daily: Skim debris, brush walls, vacuum the floor, and test chlorine/bromine levels.
•Weekly: Empty skimmer and pump baskets, test pH, total alkalinity, and calcium hardness.
•As needed: Backwash your filter when the pressure gauge is 10 PSI above the clean pressure.
Pro Tip: Regular water testing helps prevent algae growth and equipment damage.
What is the ideal pH level for a pool?
The ideal pH level is between 7.4 - 7.6. While 7.2 - 7.8 is acceptable, keeping it in the sweet spot ensures:
- Pool surface and equipment protection.
- Swimmer comfort.
- Better chlorine efficiency.
How do I test and balance my pool water?
•Use test strips for quick home checks. Aquacheck 4-in-1 Test Strips are a reliable option for homeowners.
•Bring a sample to a pool store every two weeks for a detailed lab test.
•Balance water chemistry regularly to prevent algae, stains, and equipment damage.
Key levels to monitor:
•Daily: Chlorine/Bromine & Stabilizer
•2-3 times per week: pH, Total Alkalinity, Calcium Hardness

What chemicals do I need to add regularly?
A: To achieve perfect water chemistry, you need to test for the following:
- Daily testing: You should be testing your chlorine/bromine and stabilizers levels daily and adjust accordingly. Chlorine and Bromine is your disinfectant and this should be checked daily to ensure bacteria and algae are destroyed so that your pool is safe for swimmers. Stabilizer protects chlorine from getting eaten up by the sun.
- Weekly testing: Test the following 2-3 times a week: pH, Total Alkalinity and calcium hardness. These are considered water balance parameters and protect the pools finished surfaces such as the liner in a vinyl pool or the marbelite or paint in a concrete pool. These parameters also protect your pool equipment, maintain bather comfort, and will increase the effectiveness of chlorine so that it can destroy bacteria in a pool.
How often should I backwash my pool filter?
You should backwash your filter when the filter pressure gauge is 10 PSI higher than your clean running pressure. To find your clean running pressure, do a backwash and when you run your filter back in normal filter mode after doing a backwash, mark the reading on the pressure gauge and this is your clean running pressure. Once the pressure gauge is reading 10 PSI higher than your normal clean running pressure, its time for a backwash!
Seasonal Care
When should I open my pool for the season?
In Ontario, the best time to open your pool is early spring (April - May) to prevent algae buildup and make water balancing easier.
How do I winterize my pool?
Follow these six essential steps to properly winterize your pool:
1. Clean the pool by skimming, vacuuming, and brushing to remove debris.
2. Lower the water level to 18 inches from the top (for fiberglass pools, just under the skimmer).
3. Winterize plumbing and equipment by blowing out pipes, plugging skimmer/return lines, and turning off all pool systems.
4. Add winter chemicals, including algaecide and stain inhibitors, and balance pH, chlorine, and alkalinity.
5. Cover the pool with a safety cover or winter tarp to protect against debris and weather damage.
6. Monitor during winter by checking the cover, removing snow buildup, and inspecting water levels.
A properly winterized pool prevents liner damage, frozen pipes, and algae buildup in the spring.

Do I need a pool cover for winter?
Yes, covering your pool in winter protects it from damage and makes spring opening easier.
- Shields your pool from harsh weather, ice, and falling branches that could damage the liner.
- Keeps debris, leaves, and dirt out, reducing cleanup and preventing stains.
- Prevents pets or children from falling in, especially with a safety cover.
- Extends the life of vinyl liners by protecting them from sun damage and fading.
Using a winter or safety cover saves time, money, and hassle when reopening your pool in the spring.

Saltwater vs. Chlorine Pools
Which is better: saltwater or chlorine pools?
The choice between a saltwater and chlorine pool depends on your budget, maintenance preferences, and long-term goals.
• Saltwater pools offer softer water, lower chlorine odours, and less frequent chemical handling, but they have higher upfront costs and require occasional equipment maintenance.
• Chlorine pools are more affordable upfront, effectively kill bacteria and algae, and work well in outdoor settings, but they require more hands-on maintenance and can produce strong chlorine odours.
What Are the Pros of a Saltwater Pool?
A saltwater pool offers several advantages:
• Produces a softer, silkier form of chlorine that’s gentler on your skin, hair, and eyes.
• Eliminates the strong chlorine smell common in traditional pools.
• Requires only a small amount of salt to generate a continuous chlorine supply.
• Provides steady chlorine levels, reducing the risk of algae growth.
• Removes the need to handle and store liquid chlorine.
What Are the Cons of a Saltwater Pool?
While saltwater pools have many benefits, there are a few cons:
• Higher upfront costs for installing a salt system.
• Salt can be corrosive, potentially leading to rust or equipment damage. This can be minimized by bonding pool equipment with a copper cable and bonding plate and using a sacrificial anode.
• Constant chlorine generation affects pH and alkalinity levels, requiring regular monitoring and adjustments.
• Saltwater systems contain components like the salt cell, circuit board, and flow switch, which need replacement every 3–5 years.
What Are the Pros of a Chlorine Pool?
Chlorine pools come with several advantages:
•Easy chlorine application with options like liquid chlorine, granular chlorine, and chlorine pucks.
•More affordable compared to saltwater systems.
•Chlorine pucks can be used in a chlorinator (recommended) or placed in the skimmer basket if necessary.
•Works quickly to eliminate bacteria and algae.
•Ideal for outdoor pools since cyanuric acid (stabilizer) helps prevent rapid chlorine loss from sunlight.
What Are the Cons of a Chlorine Pool?
While chlorine pools are cost-effective and widely used, they have some cons:
•Chloramines, a by-product of chlorine, can build up and create a strong odour while reducing sanitization effectiveness. Regular shock treatments are needed to break them down.
•Chlorine’s strong smell can be unpleasant for some swimmers.
•Less effective in hot water, such as in hot tubs, as it depletes quickly.
•Liquid chlorine has a high pH and requires careful monitoring to maintain water balance.
•Chlorine can be hazardous if not handled and stored properly.
Pool Repairs and Equipment
How often should I replace my pool filter or pump?
- Pool Pump Lifespan: 5-7 years
- Pool Filter Lifespan: 7-10 years
Signs you need a replacement: Loud noises, weak water flow, frequent leaks, or inefficiency.
Why is my pool losing water?
Your pool may be losing water due to:
- Evaporation (especially in hot weather).
- A leak in the liner, plumbing, or equipment.
How Do I Test For A Leak
To test for a leak follow these simple steps:
- Fill the pool to the middle of the skimmer.
- Leave the pump ON for 24 hours and measure water loss.
- Refill the pool and leave the pump OFF for 24 hours.
- Compare results:
- More water loss when ON? Leak in pool plumbing.
- More water loss when OFF? Leak in the liner.
- Same water loss? Likely evaporation.

What should I do if my pool pump isn’t working?
If your pool pump is not working, here are a few suggestions:
- Make sure the breakers are on that control the pool pump
- Make sure the pump and skimmer baskets are empty so that water flow is not restricted
- Make sure the water level in the pool is ¾ up the skimmer
Make sure the electrical connections to the pump are tight - Check the O-ring under the pump lid to ensure it’s clean and not cracked
- Make sure suction valves are open
- Make sure all plumbing connections around the pump are tight so that air is not getting into the system
If these suggestions do not work, its best to call a pool professional to investigate further.
Pool Cleaning Issues
Why Is My Pool Water Cloudy?
Cloudy pool water is a common issue caused by a variety of factors, including:
• Unbalanced water chemistry: Check your chlorine, pH, alkalinity, and calcium levels to ensure they are within the proper range.
• Poor circulation: Ensure your pump and skimmer baskets are clean, backwash your sand filter (or clean your cartridge filter), and check for any blockages in underground plumbing that might be restricting water flow.
• Variable speed pump settings: If you have a variable speed pump, try running it at a higher speed to improve circulation.
• Algae growth: Algae blooms can cause water to appear cloudy.
• Contaminants in the pool: Vacuum, brush, and skim your pool to remove debris that could be contributing to the cloudiness.
• Environmental factors: Heavy rainfall, windstorms, or even a recent pool party with lots of swimmers can introduce excess contaminants, requiring additional cleaning, vacuuming, or shocking.
How Do I Get Rid of Algae in My Pool?
Algae can be stubborn, but with the right treatment, you can clear it up quickly. At Bremner Pool & Spa, we use an effective algae removal process.
What Types of Algae Grow in Pools?
• Green Algae – The most common type, usually caused by poor water chemistry or circulation.
• Mustard Algae (Yellow Algae) – A more resistant form that clings to pool walls and surfaces.
• Black Algae – Found mainly in concrete pools; harder to eliminate due to deep root systems.
Did You Know? A green pool isn’t always caused by algae—it can also be due to metals like copper or iron in the water. Before treating, get a water test from a local pool store to diagnose the issue correctly.
How Does Algae Develop in a Pool?
Algae growth is usually linked to:
• Unbalanced water chemistry – Neglecting water balance can lead to algae blooms.
• Poor circulation and filtration – Dirty filters and weak water movement encourage algae.
• Hot temperatures and prolonged sun exposure – Warm, stagnant water is the perfect breeding ground for algae.
• Keeping a solar cover on too long – Heat trapped under the cover can accelerate algae growth.
• Airborne spores – Algae can enter the pool through wind, rain, or organic debris.
What Should I Do Before Treating Algae?
For the best results, follow these steps before starting algae treatment:
- Run your pump continuously at max speed – Strong circulation is key to killing algae.
- Brush walls and floor – Scrub algae off surfaces and rinse the brush after use.
- Remove debris – Leaves and organic matter can feed algae.
- Uncover the pool – Algae thrive in warm, stagnant water, so allow the pool to “breathe.”
- Adjust water jets – Point them downward at a 45-degree angle for better circulation.
- Turn off the heater – Lower temperatures make chlorine more effective.
- Test and balance water chemistry – Ensure proper pH and chlorine levels before treatment.
How Do I Treat Algae in My Pool?
Once prepped, follow this algae treatment process:
- Superchlorinate the water – Use a chlorine-based shock such as CHLOR GRAN, SHOCK PLUS (diluted in a bucket first), or liquid chlorine. If the pool is extremely green, additional doses may be required.
- Wait 1 hour, then add ALG-PRO 60 ALGICIDE – This helps kill the algae more effectively.
- Monitor the water colour – It should change from green to cloudy white. If it remains green, apply another dose of shock.
- Clarify the water – Once the green is gone, add SPARKLE PHOS and keep the pump running at max speed for 24 hours.
- Vacuum dead algae – If dead algae settle on the pool floor (it looks like sand), vacuum it using the DRAIN or WASTE setting on your filter. Be sure to refill the pool afterward.
- Use clarifiers – Add SPARKLE or CLARIFIER TABS to further clear up the water.
- Clean the filter – Use FILTER CLEANER to remove any residual algae in the filter.
Pro Tip: If you have a sand filter, backwash when pressure gets too high. If using a cartridge filter, remove and hose down the cartridges to clear out algae buildup.
What Causes Stains on My Pool Walls, and How Do I Remove Them?
Stains can come from various sources, including:
• Algae residue – A past algae bloom may leave behind stains.
• Metals (Iron, Manganese, Copper, Cobalt) – Metals in water can cause brown, green, or blue stains.
• Scale buildup – Calcium deposits create white, rough patches on surfaces.
• Mineral staining – Ionizer systems can sometimes lead to mineral deposits.
• Organic debris – Leaves and plant matter left in the water too long can cause discoloration.
How to Remove Pool Stains:
• Use a Stain-ID Kit (such as Jack’s Magic Stain-ID Kit) to determine the stain type before treatment.
• Follow the appropriate stain-removal process based on the test results.
Energy Efficiency and Costs
What is the average yearly cost to maintain a pool in Toronto?
If you hire a pool professional such as Bremner Pool & Spa to open, close and provide weekly maintenance for a summer, this will cost around $3,100 + HST plus cost of chemicals and parts. If a homeowner opens, closes and maintains his own pool, the cost for chemicals on average for the summer will cost roughly around $700 + HST in Toronto.
How can I reduce the cost of running my pool?
You can reduce the cost of running your pool by implementing the following measures:
Install a variable speed pool pump
A variable speed pool pump gives you more control as it has a built in timer which allows you to customize a schedule and run the pump at different speeds throughout the day, compared to a single speed pool pump which runs at the same high speed throughout the entire day. You can program a variable speed pump to run at a lower speed during the day when electricity costs are the most expensive, thus, reducing your monthly electricity bill. The piece of pool equipment that will cost the most in energy is your pool pump, so you definitely want to consider purchasing a variable speed pool pump to achieve savings on your electricity bills!
Install LED Pool light bulbs
There are pool lights available on the market that are LED lighting, which are a lot more energy efficient and last longer than an incandescent or halogen bulb.
Use a solar blanket
When the pool is not in use, consider covering the pool with a solar blanket. A solar blanket will help to retain heat in the pool, keep debris out of the pool, and reduce the amount of water lost through evaporation. By reducing evaporation, you will save money by not having to supply fresh water, re-heat the water as well as add chemicals to balance the water.
Install a cartridge filter instead of a sand filter
The main difference between a cartridge filter and a sand filter is with a cartridge filter, there is no need to backwash. By eliminating the need to backwash, you will save money by not having to refill your pool with fresh water and add chemicals to balance the water.
Consider using a robotic pool cleaner to keep your pool clean
A robotic pool cleaner is an automatic cleaner that comes with a built in computer processor and its own built in filtration system. It does not use your existing pump and filtration system. Simply plug the cleaner into an electrical outlet close to your pool and it will go around and clean the entire pool on its own.
You will achieve energy savings by not having to use your pool pump or your booster pump (if you have a pressure side cleaner) to vacuum your pool.
Install an Ozone or UV system to help keep your pool clean
Chlorine is the popular choice amongst pool owners to disinfect your pool; however, chlorine is not safe for the environment and can be toxic. There are options available in the market that is more environmentally friendly than Chlorine such as Ozone and Ultraviolet (UV) systems. It’s important to note that both of these systems will significantly reduce the need for chlorine. However, you will still need to add a bit of chlorine to help maintain a residual in the pool.
Ozone – Ozone is a gas that is produced with an ozone generator. An ozone generator will use the oxygen in the air and convert this to an ozone gas, which is then used to disinfect the water.
Ultraviolet (UV) systems – UV systems use UV lamps to generate a UV radiation to disinfect water. Pool water passes through the UV system where it is exposed to UV radiation.
Solar heater
A solar heater is an excellent way to save on your gas bills as you are using the power of the sun to heat your pool. It utilizes solar panels to collect energy from the sun which then heats the water in your pool. Water is pumped to the solar panels to be heated and returned back to the pool.
Heat Pump Pool Heater
Heat Pumps have been around for quite some time now and are a popular form of heating. They are more energy efficient and environmentally friendlier than gas heaters. The way it works is pretty simple. It collects the free ambient heat in the air and transfers it into the pool water. Heat pumps require an electrical connection to allow it to collect the heat and transfer it into the water. The amount of energy that a Heat Pump uses is pretty low. Heat Pumps do have a higher upfront purchase cost, but over the long term, it is much cheaper in operating costs compared to gas heaters.
Are solar covers or heaters worth it?
Yes, solar covers and heaters are worth it. A pool heater will allow you to enjoy your pool at the perfect comfort level. You can control the temperature of your pool during swimming pool season, especially early in the spring or when fall arrives when temperatures are chilly. A solar cover will allow you to retain heat in the pool as well as reduce water loss to evaporation, thus, saving you money!
How much electricity does a pool pump use?
A single speed pool pump uses a lot of electricity. On average, in the City of Toronto, it costs roughly $170 to $215 on average per month in electricity to run a ¾ HP single speed or 1HP single speed pool pump 24 hours a day, 7 days a week. If you would like to reduce your monthly electrical bill, consider purchasing an energy efficient variable speed pool pump which can reduce your monthly electricity bill by up to 80% when programmed correctly.
Pool Usage and Comfort
How can I keep my pool warm?
You can keep your pool warm with the purchase of a pool heater. A pool heater can be powered by natural or propane gas, electricity, or an environmentally friendly heat pump. Once you have a heater to heat your pool, it is best to use a solar blanket to cover your pool in order to retain that heat in your pool.
What’s the best way to remove debris from my pool?
- You have one of 3 ways to vacuum your pool:
You can manually vacuum your pool by purchasing a vacuum pole, vacuum head and a vacuum hose. You would connect the vacuum head to the vacuum pole and you would attach one end of the vacuum hose to the vacuum head and the other end would attach to your pool skimmer and you would move it around manually in order to clean your pool. This process is more labour intensive; however, it is the cheapest way to vacuum your pool. - You can purchase a robotic pool cleaner. You would plug it into an outlet near the pool and the robot will drive around the pool floor, walls and waterline and clean your pool automatically. Robotic pool cleaners run independent of your pool pump and filtration system. The robotic cleaner has its own filter cannister that collects debris. The robot can also be programmed to run on a schedule, and you can select different cleaning modes. A Robotic cleaner is more expensive to purchase than a manual vacuuming system, however, on a positive note, the robot will automatically clean your pool for you which will make your life a lot easier and free up your time.
- Suction side or pressure side automatic cleaners. Suction side automatic cleaners plug into your skimmer and rely on your pool pump and filter in order to operate. Pressure side cleaners rely on a separate booster pump in order to function.
