Water Balance Basics
Alkalinity level in pool system is a measure of hydroxides, carbonates, bicarbonates and other alkaline substances. It is also termed as buffering capacity of water and helps to keep a balance of the pH level too. For ‘gunite’ and concrete pool systems, the alkalinity levels should be maintained at the 80-120ppm range. The level of 125-170 ppm needs to be maintained for painted, vinyl, and fiberglass pool systems. These levels need to be maintained or else pools may become defunct and unhealthy. Changes in the alkali levels need to be adjusted with the aid of base and acids. Whenever the alkalinity level gets lowered it is raised by adding a base. A rise in alkalinity is lowered by adding acids to water. These steps can be easily avoided and the alkalinity balance of pool systems maintained with the use of cartridge filters. This is because the cartridge clogs all particles that alter the alkalinity levels of pools. Hence, it becomes mandatory for pool systems users to make use of the new filters.
Cartridge filters can remove chemicals like chlorine as the polyester filament used as its filtering medium has the capability to adsorb chemicals on its surface. As the adsorption continues, it shows up in the filament that henceforth requires cleaning or a replacement. While using the cartridge filter, people can learn from its taste, appearance and smell as when it is necessary to change the filter. It is true that it is good to add chlorine in water as it is effective in killing germs and parasites. But too much of suspended chlorine makes it a poison. It damages delicate body tissues whenever chlorine gets adsorbed into our body through the skin or via intakes. Pool water contains Chloramines that is the cause of red eyes. Moreover, high level of chlorine in water, releases gas that causes breathing difficulties. It also leads to respiratory problems when chlorine combines with other organic chemical compounds. This is the reason why the chlorine level in water needs to be kept balanced. Cartridge filters are good in this respect for they trap free chlorine ions and adsorb them on the surface of the filtering medium. This is what keeps the pond water safe from excessive chlorine concentration for swimmers.
The use of chemicals like chlorine is necessary for maintaining the balance of pool water. When sand filters are installed the use of Silica sand and angular sand work well. But when a cartridge filter is brought to use, it serves as a potential medium for coagulating dirty particles that alter the chemical balance of water. This filter is way ahead of all other filtering equipments to keep swimming pool water clean. Its cartridge serves the sole purpose of pool water clarity maintenance. It purifies water by trapping impurities.
