Wildfires: how to protect your pool from smoke and ash

Even far from a fire, smoke and windborne particles can reach your pool. The goal is not to use more products, but to follow a simple method: remove debris, maintain good filtration, test the water, and treat only what needs to be treated.

Smoke and fine particles can settle on the water's surface and place additional demands on filtration.

What to monitor

Possible effects on your pool

Water balance

Ash can change the pH and increase sanitizer demand.

Water clarity

Very fine particles can make the water look dull or slightly cloudy.

Filtration

Baskets, cartridges, or filter media may become clogged more quickly.

Visible debris

Soot and ash should be physically removed before adding any products.

Action plan

What should you do if ash falls into the pool?

1. Remove debris

Use a leaf net and empty the skimmer baskets.

2. Brush the surfaces

Stir the fine particles back into suspension so they can be filtered.

3. Circulate the water

Monitor the filter flow rate and pressure during the smoky period.

4. Test the water

Check the pH and sanitizer, then adjust only as needed.

5. Clean the filter

Backwash or clean according to the type of filter and how dirty it is.

6. Clarify as needed

If the water remains cloudy after filtration, a clarifier can help capture fine particles.

1. Test the pH and sanitizer first

Avoid treating the water solely because the sky is smoky. After a period of smoke or ash deposits, first test the pH and sanitizer level. A complete laboratory analysis may be useful if the water changes quickly or the situation persists.

For a saltwater pool, there is no need to automatically increase the generator's output. Adjust it based on the water test results and the treatment system used.

2. Prioritize filtration

In most situations, filtration does much of the work. Keep circulation efficient, empty the baskets regularly, and monitor the filter pressure. An abnormal increase in pressure or a decrease in flow often indicates that cleaning is needed.

3. Check phosphates only when necessary

Phosphates may become relevant if a significant amount of ash, runoff water, or flame retardants has reached the pool. It is best to test before treating.

If the results show a high level, a targeted treatment can then be used according to the manufacturer's recommendations.

Two useful products

Use only if your situation warrants it

We are intentionally keeping the selection short: one product for confirmed phosphates and one clarifier for fine particles.

4. When should the filter be cleaned more thoroughly?

If the flow remains low, the pressure rises quickly, or the filter has captured a large amount of particles, a more thorough cleaning may be useful. For a sand filter, this may include backwashing and, if needed, a filter media cleaner. For a cartridge filter, remove and clean the cartridges according to the manufacturer's recommendations.

Key takeaways

The right strategy: clean, filter, test, then treat

A pool exposed to smoke does not automatically need a long list of products. Start with physical actions and filtration. Then let the test results guide chemical adjustments.
