A clean pool is the centerpiece of a great backyard, but keeping it that way takes more than just scooping out leaves. Many pool owners unknowingly make mistakes that can lead to murky water, damaged equipment, and even health hazards. If you want to avoid unnecessary maintenance headaches, here are some common pool cleaning mistakes—and how to fix them.

Mistake #1: Not Cleaning Your Pool Filter Regularly

Your pool’s filter is responsible for trapping dirt, debris, and bacteria, but when it’s clogged, it can’t do its job effectively. A dirty filter restricts water flow, putting strain on your pool’s pump and causing cloudy water. The solution? Check and clean your filter at least once a month, or more often if your pool gets heavy use. If you’re using a pool cleaner, make sure it isn’t overloading the filter with excess debris.

Mistake #2: Ignoring pH and Chlorine Levels

Balanced pool chemistry is crucial for clear, safe water. If your pH is too high, chlorine becomes ineffective, leading to algae growth. If it’s too low, the water becomes acidic, which can damage pool surfaces and irritate swimmers’ skin. Test your pool water at least twice a week and adjust chemicals as needed. Using the best pool cleaner helps, but it won’t replace the need for proper chemical balance.

Mistake #3: Adding Chemicals at the Wrong Time

Pouring pool chemicals directly into the water in the middle of a hot, sunny day can cause them to evaporate before they even have a chance to work. Instead, add chemicals in the evening or early morning when the sun isn’t as strong. This allows chlorine and other treatments to fully circulate and take effect, keeping your pool sanitized longer.

Mistake #4: Brushing Your Pool Too Little (or Not at All)

Vacuuming your pool with a pool cleaner is great, but it doesn’t remove all the grime. Algae and calcium deposits tend to build up on walls and steps, so brushing your pool at least once a week is essential. Pay special attention to corners, behind ladders, and other areas where debris collects.

Mistake #5: Running Your Pool Pump for Too Little Time

Your pool’s pump is the heart of its circulation system, ensuring chemicals are evenly distributed and debris is filtered out. Many pool owners try to save on electricity by reducing pump run time, but this often leads to stagnant water and algae growth. Ideally, your pump should run for at least 8 hours a day to maintain proper water circulation. Combining this with the best pool cleaner will keep your pool in top shape.

Mistake #6: Overloading the Pool with Shock Treatment

Shock treatments are essential for killing bacteria and breaking down contaminants, but using too much can be just as bad as not using enough. Over-shocking can bleach your pool liner, damage equipment, and irritate swimmers’ skin. Always follow the manufacturer’s guidelines and only shock your pool when necessary—typically once a week or after heavy use.

Mistake #7: Not Covering Your Pool When It’s Not in Use

A pool cover isn’t just for keeping leaves out—it also reduces evaporation, helps maintain water temperature, and prevents algae growth by blocking sunlight. Leaving your pool uncovered means more debris, faster chlorine loss, and more maintenance work. Invest in a good pool cover to cut down on cleaning time and chemical use.

Final Thoughts

Avoiding these common mistakes will help you maintain a clean and healthy pool without unnecessary stress. A little extra attention to your filter, water chemistry, and cleaning schedule goes a long way in preventing costly repairs and frustrating pool problems. Pairing good maintenance habits with the best pool cleaner ensures that your pool remains crystal clear and ready for a swim whenever you are.
