Getting Know About Pool Algaecide
Ever since pools became a part of the household facility, scientists together with chemists have worked on solving these strains. Then, they figured out a solution to detect all algae problems, called algaecide.
Basically, algaecide is known as a chemical treatment killing and preventing algae growth. This product is quite effective because it’s immune to mineral content, pH, sunlight, and water temperature.
Learning About Pool Algaecide and the way it works?
There are 4 types of pool algae known to science. Except for the red algae, the rest 3 are commonly seen:
Green Algae – Known as blue-green algae, is the most common kind and all it takes is warmth, water, and sunlight to grow.
Yellow Algae – This is another form of blue-green algae colored with yellow carotenoids. These chlorine-resistant algae can grow without sunlight.
Black Algae – This is a strain of green algae that favor plaster pools, where it can put down roots. It is protected by a thick multilayer cover from chlorine and most of the algaecides.
Red Algae – Known as pink slime or pink algae, it is a different type of bacteria that are chlorine-resistant and light-free survival.
Algaecides play an essential role in maintaining your swimming pool safe from algae.
It can either be seen as algaecide to kill tiny, single blooms or as algae-stat to stop and handle pool algae development.
Different algaecides mean there are different ways to control algae:
Quat Pool Algaecides – Usually called Quaternary Ammonium compounds – general detergents; that’s why overuse of this product might lead to some foaming in your pool.
Microbial disinfectants found in this product are normally attached to the unfavorably charged part of algae. The outside cover of the algae will be destroyed and penetrated by chlorine.
They come from 10 to 50% strengths or concentrations and quite pocket-saving.
Polymer Pool Algaecides – Polyquat elements in this algaecide with long chains of carbon, which are benefited from both staining-free and non-foaming substances.
Just like Quat Pool Algaecides, this product has a positive charge attaching to a negatively charged algae, rapidly expand over the organism then smoothen its cell.
These products are two times effective than the Quat, long-lasting and more expensive. Popular for four-seasons pools, polymers come in 30-60% concentrations.
Metallic Pool Algaecides – This consists of copper ions which have been used in centuries for water treatment.
Amino acids are bonded or chelated by the cooper to minimize any possible stains from continuous use, which is sometimes seen mainly as a problem for plaster pools.
Like other two algaecides, these products positively charge and attach to the algae, weaken it for chlorine to penetrate. It is recommended to treat green and black algae 7% concentrations.
