Question

Which type of algae is the most difficult to control in a pool, often requiring superchlorination and brushing to eliminate:

A) Mustard algae
B) Green algae
C) Black algae
D) Blue-Green algae.

Answer 1

The most difficult type of algae to control in a pool is black algae, which requires super chlorination and brushing for elimination. The correct option is C)

Step-by-step explanation:

The type of algae that is most difficult to control in a pool, often requiring super chlorination and brushing to eliminate, is Black algae. Black algae are known for their resilience and ability to adhere strongly to pool surfaces, making them more challenging to eradicate than other types, such as mustard algae, green algae, or blue-green algae. To effectively remove black algae, it may be necessary to engage in super chlorination, which involves raising the chlorine levels significantly higher than usual, combined with vigorous brushing to break through the algae's protective layers.
