Problem

You are finding algae in your spa water.

Origin

This typically results from improper chemical treatment of the spa.

Why Algae in My Pool?

Algae are naturally found in the environment (soil, air) and are transported into the pool water by bathers, rain, wind, etc.

The appearance of pink algae is associated with:

- Elevated water pH

- Inadequate disinfection and maintenance

- Insufficient hydraulics (insufficient filtration time)

What is Algae in My Pool?

We talk about algae, but algae are, in fact, a type of bacteria.

They are a slimy/viscous substance that initially appears on plastic parts: PVC, fittings, skimmer baskets, cleaners, inflatable liners, solar covers, etc.

How to Get Rid of Algae and Remove Stains?

- Lower the pH below 7.0 (this will enhance the effect of shock chlorination).

- Vigorously brush the pool walls and the floor (where algae have developed).

- Continuous filtration.

- Leave any contaminated plastic objects in the pool (toys, mattresses) to prevent recontamination.

- Perform shock treatment. If you use chlorine, use shock chlorine. Otherwise, you can use a product based on hydrogen peroxide, such as REVATOP.

- Add a special pink algae algaecide: REVAGUARD (compatible with all pool treatments).

- 24 hours later, raise the pH to between 7.2 and 7.6 and adjust your disinfectant levels.

- Stop filtration after 72 hours and clean the filter.

- Resume routine treatment within the specifications.

Note: Do not swim during the entire duration of this operation.

After this treatment, you will be in the clear!

What Causes Water Contamination?

Pool or spa water is exposed to various forms of contamination during its "lifetime." Each swimmer inevitably brings organic and inorganic matter, as well as germs eliminated by the body, which end up in the pool water (see the table below). Outdoor pools are also contaminated by sun products, grass, soil, and foliage. Furthermore, air circulation introduces other microorganisms and contaminants into the water, including dust, pollen, and algae spores (also in indoor pools).
