Chlorine Reduction for Pool Plants: Safe Levels & Timeframe

It can take several days to a few weeks for the chlorine level in a swimming pool to drop to a safe level for plants. The time it takes will depend on several factors, including the initial chlorine concentration, the water temperature, and the amount of sunlight the pool receives.

In general, chlorine levels in swimming pools should be between 1 and 3 parts per million (ppm) to be safe for swimming. However, plants are much more sensitive to chlorine, and even low levels can be harmful. For most plants, chlorine levels should be no higher than 0.1 ppm.

To lower the chlorine level in a swimming pool, you can stop adding chlorine and allow the chlorine to dissipate naturally. You can also use a chlorine neutralizer, which will chemically remove chlorine from the water.

The following tips can help you lower the chlorine level in your pool more quickly:

* Increase the water temperature. Higher temperatures cause chlorine to evaporate more quickly.

* Expose the pool to sunlight. Sunlight helps to break down chlorine.

* Use a pool cover. A pool cover will help to prevent chlorine from evaporating.

* Add plants to the pool. Plants will help to remove chlorine from the water.

Once the chlorine level has dropped to a safe level, you can add plants to the pool. Be sure to choose plants that are tolerant of chlorine and other pool chemicals.

Here are some plants that are tolerant of chlorine:

* Water hyacinth

* Water lettuce

* Duckweed

* Salvinia

* Anacharis

* Elodea

* Hornwort

* Cabomba

* Hygrophila

* Rotala
