5 Solutions to the Most Common Pool Water Problems
You’ve probably asked yourself many times “What do I do now?” when noticing something isn’t right with your pool.
Fortunately, many of these problems are relatively common and easy to solve.
Innowater explains how. Keep reading.

My pool has high residual chlorine
If when measuring your pool’s chlorine level the amount of chlorine is too high, it’s likely due to deficient chlorination processes in which some part of the process hasn’t been performed properly.
In other cases, it may also be due to the presence of organic matter and nitrogen compounds (ammonia) in the water. Generally, this is caused by a bird or small rodent that dies after falling into the water.
Possible solutions:
- Adjust chlorine levels.
- Clean the filters.
- Improve bather hygiene.
- Shock treatment.
- Add UV or Ozone.
My eyes and skin are irritated after swimming
If, after enjoying a swim in your pool, you notice itching on your skin or eyes, or experience redness and irritation, it’s most likely that the pH is outside the recommended range or that the amount of combined chlorine is too high.
Possible solutions:
- Adjust to pH 7.2–7.6.
- Reduce chloramines.
- Possible shock treatment.
My pool water is cloudy
One of the most common problems pool owners encounter. It’s often caused by improper filter operation, although sometimes it may be due to high pH values or excessively high water alkalinity.
In salt chlorination pools, it may be because the amount of salt has been exceeded and it’s not dissolving properly.
Possible solutions:
- Raise pH to 7.8.
- Clean the filter.
- Add flocculant and stop the filter for 1 hour.
- Restore pH and alkalinity values.
- Maintain filtration for 10 consecutive hours.

The pool water is green
Another of the most common pool problems. It occurs due to the presence of algae in the water and on the walls. Fortunately, the solutions are varied and very simple.
Possible solutions:
- Clean and remove algae by brushing the floor and walls.
- Adjust pH between 7.2–7.6.
- Add flocculant and leave filtering for 24 hours.
- Finally, add double the amount of algaecide.
My pool has foam in the water
This is a problem that arises when trying to solve others. It occurs when there’s an increase in the concentration of algaecides in the water that cannot be purified or filtered by the system. This increase is caused by poor measurement of the amount of product used.
Possible solutions:
- Raise pH to 7.8.
- Clean the filter.
- Add flocculant and stop the filter for 1 hour.
- Restore pH and alkalinity values.
- Maintain filtration for 10 consecutive hours.
Final Recommendations for Pool Problems
At Innowater, we remind you that if you have doubts about the origin of the problem or possible solutions, it’s always best to consult a professional.

Salt chlorination for pools is a treatment system that generates pure chlorine from the salt dissolved in the water, through an electrolysis process. A sustainable, automated, and safe treatment for swimming.
