Algae reappear in pools mainly because a chemical treatment failed to completely sanitize both the water and surfaces. In some cases, poor circulation in the filtering system prevents chlorine from getting distributed throughout the pool and cleansing the water. Water misdirection usually occurs because some pools are designed to redirect the water to the surface, helping pool owners collect debris much more easily and giving a moving effect to the water. Unfortunately, this allows generally the bottom areas of the pool to have little to no circulation and makes the use of algaecide ineffective. Removing organic material like leaves is also important because decomposition changes the pH level and allows algae growth to speed up. In addition, algae are costly and involve constantly filtering the pool daily with more chemicals to fight off the unsightly color.
Having algaecide applied everywhere is crucial as well because various algae species have spores that can survive outside of the pool. Once a spore comes into contact with the water, expect to fight another infestation once again. The most common form of algae though is the green variety and it can be eradicated through pool shock. Granular and highly concentrated, this chlorine quickly makes the water an unlivable environment. It’s also recommended that you do a pool shock once a week, to prevent algae spores from blossoming into a bigger problem. Scrubbing or brushing the floor, walls and steps also stops algae from firmly placing their roots in cracks on the surface. Running your pool at night will further reduce the risk of an algae infestation as well. Chlorine effectively keeps the water in your pool sanitized by removing most bacteria and algae altogether, but any buildup will make any effort to maintain the pool useless.
