Natural Methods of Controlling Algae Growth in Outdoor Swimming Pools

Abstract

Outdoor swimming pools are among the places prone to algae growth thanks to having nutrients including nitrate and phosphate, as well as having exposed to enough light. Also, the algae existing in the swimming pools may engender likely troubles such as smell, color, or bad scenery, whence making the algae treatment a must. Reducing the nutrients by growing aquatic plants is amongst effective methods to control algae in the swimming pools. In this research, a pilot test sample was fabricated via simultaneous planting of three aquatic plants- water lily, lemna, and sea lettuce- in the separated section of the main area so that the pool water is used, to study the effects of the plants on the number of algae, on concentration of nitrate, phosphate, and water turbidity. The results showed that the concentration of nitrate, phosphate, and water turbidity in the pilot was getting low by a large amount compared with the control sample. This was evidence that the three plants water lily, lemna, and sea lettuce were conducive to algae decline. Therefore, one could hold in check the algae growth in swimming pools through developing the research results without using chemical materials.
