On a hot summer day, we all would like to jump into a cool and stimulating pool and after that, as the sun sets, there is no better way to relax than to slip into your own backyard spa, summer or winter. However, taking pleasure in all needs some regular attention. Keep in mind that the water in your pool and spa has been an ever-changing situation that calls for regular and vigilant monitoring. For some people, this means, employing an expert service technician to come by one or two times a week. However, you can look after your pool and spa yourself. The necessity to treat water has been generally accepted for a long time. Cleanliness, particularly, is known as a way of controlling infectious diseases. Following are just some of the more general problems connected with pool maintenance, and some instructions for resolving them.Green waterIf the pool water is clear, green water may be attributable to the dissolved iron, inappropriate use of anthracite filters or the use of iodine or bromine. Chlorination will change the dissolved iron into a red-brown precipitate that can be vacuumed and sorted from the pool. Appropriate pH control will put the water off from the dissolving iron from the pipes and filters of the pool. In extreme situations, the settling procedure can be assisted through spraying an ounce of crushed aluminum sulfate on top of every 100 square feet of the surface of the pool. Let the aluminum settle quietly during the night. Be certain the pH of the pool water is higher than 7.6 earlier than using aluminum. Cloudy green waterGenerally, owing to the growth of algae, instant super chlorination and maintaining appropriate free chlorine remains may resolve the problem. An algaecide may be required. In situations that have progressed past the curable phase, drain the pool and rub the floor and walls with muriatic acid with great care. Dark and skidding spotsThe growth of algae may generate dark and, or skidding spots on the sidewalls and bottom of the pool and spa. Use the same procedure for treating the cloudy green water problem. Occasionally, sprinkling a small number of particles of calcium hypochlorite straight on the spots may prevent the algae growth. However, this may result in white spots on a colored liner or painted bottom, as well. Dark, skidding spots in swimming pools and spa on the deck may be treated with calcium hypochlorite as well, but the solution must be rinsed in detail earlier than allowing people to use the area. Useful tipIf you are not aware of the pool and spa operations, there are many certification courses that are designed to offer people like you, the basic knowledge, methods, and skills of pool and spa operations.
