Types of mustard algae

Mustard algae can be of two different types depending on the level of toxicity. The first form is non-toxic but can still cause skin irritation and itching.

The second type of mustard algae leaves a greasy residue on your pool walls, which may be unsightly to the eye.

Cause of Mustard Algae in a Pool

The most common cause of mustard algae is over-chlorination, which can be caused by a lack or too much maintenance on your pool equipment.

This is because chlorine reacts with the oils and fatty acids in your pool water. It then creates a chemical reaction that produces free radicals.

A free radical is an unstable atom or molecule which has lost its electrons to become highly reactive by generating other molecules through oxidation reactions.

This condition may occur sooner if you have not maintained your pool regularly. It may fluctuate if you have been using too much chlorine, which is the case with a poorly maintained swimming pool.

If this chemical reaction continues in pools at high levels, they can be damaged due to the free radicals produced from oxidation reactions. The damaged pool walls are the breeding grounds for mustard algae.

Effects of mustard algae

Mustard algae in swimming pools may cause skin irritation and even irritate your eyes if you look at them directly.

The slime on the pool walls makes it difficult to see how dirty your water is. This can be a safety concern for children.

It also affects indoor pools; it can also be found in many outdoor pools since they receive the same chemical reaction as indoor pools.
