Why you should test your pool water before closing you pool.
As the temperature drops, it is time to think about when and how to close the pool down! Winterizing a pool in Winnipeg is essential to ensure the best protection, sanitization, and spring opening for your backyard getaway! While lowering the water level, covering the pool, and winterizing the equipment are all essential steps – there is a task that should never be overlooked:
Testing your pool water before closing it!
Proper pool chemistry plays a major role in keeping your pool protected throughout our cold winters! Here is why testing your pool water before closing matters AND how it can make your pool opening next spring much easier! Aqua-Tech recommends bringing in a water sample one week before your closing date, so you have time to balance the water before its time to shut it down for the winter.

- Balanced water helps protect pool surfaces
Before closing the pool down, ensuring the water is properly balanced is essential for the pool surfaces. Proper pH, alkalinity, and calcium hardness help protect the liner, pool surface, and other components from unnecessary damage.
Water that is too low in pH or too high in pH can lead to corrosion, staining, scaling, or deterioration over winter. Balancing before winter ensures the best protection while the pool is done for the season! You can shop for all the balancers you might need in store when you bring in your water sample, or you can order online here: Pool Chemicals – Balancers (Ph Alkalinity Calcium) — Aqua-Tech
- Proper chlorine levels keep the water clean
Even though the pool won’t be in use, making sure the water is clean still matters! Maintaining proper sanitizer levels at closing helps control bacteria and organic contaminants that remain in the water.
A properly sanitized pool is far more likely to stay in good condition under that winter cover, helping tremendously when spring arrives!
- Testing can help prevent algae growth
Nobody wants to uncover their pool in the spring to a cloudy or green pool!!
Testing the water before closing allows you to make any necessary chemical adjustments before the pool goes dormant. Combined with proper winterizing procedures, balanced and sanitized water can help reduce the risk of algae growth during the off-season. Adding a proper winterization kit with algaecide can help prevent opening green in the spring! Shop in store or click the link to purchase online here: Pool Chemicals – Opening/Closing — Aqua-Tech

- Lastly, it makes spring opening much easier!
A swimming pool is a significant investment and your family’s enjoyment! One of the biggest benefits to testing before closing is the time saved in opening, allowing for more family fun and enjoyment in the pool instead of time clearing it.
Improper water chemistry can contribute to scaling, cloudiness, staining, and algae growth over winter. Addressing chemistry issues before closing gives an amazing starting point in the spring and the opening procedure a piece of cake!
