Swimming Pool Terms That Start with A

An acid demand test determines how much acid is required to decrease the swimming pool water pH level.

Acid demand of swimming pool water generally describes the requirement of acid that needs to be added to the pool water to bring the pH level down, and is measured with an acid demand test.

Above ground pools are swimming pools built on top of the ground, and cost much less than permanent in-ground swimming pools as they are cheaper to build and install.

An algaestat is a substance that is designed to stop the growth of algae by eliminating the algae food source.

Algae bloom describes the uncontrolled growth of algae, where individual algae cells divide, grow, and further multiply exponentially, to the point the water surface and often subsurface is completely overrun with algae growth.

Aggressive water is a water industry term to describe the water actively seeking to gain minerals and metals, resulting in the corrosion of iron and copper surfaces and dissolving of concrete and stone surfaces.

Algaecides are chemicals and systems intended to kill algae growth in pool water, and prevent future algae blooms.

Algae are small, plantlike organisms that are commonly found in swimming pool water.

Acids in swimming pools increase the acidity of pool water, and encourage corrosion of pool surfaces and equipment.

Acidity describes how much acid is present in swimming pool water, or how much the water behaves like an acid.

Alkalinity measures the acid-neutralizing capability of swimming pool water.
