Often, many water and surface problems can be handled by the individual pool owner. The information below provides solutions to some common pool issues. Always make sure the water is properly balanced prior to any addition of corrective chemicals.

Water Problem Description Solution Prevention
Algae The most common type of algae is the floating green. Other types include yellow/mustard and black (which is really a shade of dark blue). Algae can easily take root in pool walls and bloom quickly, sometime within hours. An algaecide is the main artillery. Just make sure you’re using a algaecide designed to combat you type of alga. Copper and silver are the most common active ingredients in algaecides, though there are some nonmetallic formulas that remove algae nutrients from the water thereby starving the organisms. Of course, chlorine also kills algae. You might consider brushing the algae from the pool wall to expose all the cells to algaecide. Green or yellow algae can be brushed away using a nylon or polyester brush, where as black algae may require a wire brush. Apply the algaecide regularly as recommended on the product label. Note that some products are designed to kill algae, others to prevent algae and still others to do both. Make sure you`re using the right product for the job at hand
Cloudy Water Many things can cause cloudy water, including unbalanced water and poor filtration. Assuming the problem us water relater and not the fault of equipment, the problem could be caused by algae, high levels of Total Dissolved Solids(TDS), body oils, low sanitizer levels or high pH or calcium hardness levels. Shocking the water usually clears up any cloudiness, especially if the culprit is algae. If shocking doesn’t work, use a clarifier to help the filtration system to do this job. Use a clarifier regularly, following the instructions on the product label. Make sure the clarifier you select is compatible with the sanitization system you’re using
Stains Stains cn be caused by organic debris that get into the water or by metals that come out of solution when the water isn’t kept in balance. Copper can cause greenish blue, blue or black stains. Iron stains are red or brown. Manganese stains are tan or purple. A gray stain, however can mean a litany of other things – from oxidized metal or scale deposits to moisture trapped in the plaster or even a towel burn. Balance the water before treating the stain or else it might occur again. Use a stain remover, available from your pool or spa supply store, that’s designed to treat the type of stain you have. If your pool is plaster and is severely stained, you might need to consider draining the pool and having the surface acid-washed by a professional. Keep the water balanced all the times. Use a stain preventive or metal remover when starting up your pool or spa and whenever fresh water is added
Scale Scale occurs when minerals, especially calcium, come out of solution. The result is white, gray or even brown deposits that mar the and spa surface and can damage equipment. Scale most often occurs when pH, total alkalinity or calcium hardness levels are high Make sure the water is properly balanced. Then use a Scale-removing and thoroughly brush the walls to suspend the scale so the filter can trap it. You may need a special title cleaner to remove scale deposits from the waterline area, where they’re most noticeable. Keep the water balanced all the times
Corrosive Water Corrosive water is acidic. It can damage pool and spa equipment and etch pool surfaces Use soda ash (sometimes sold unde the name like pH-Up) or sodium bicarbonate to raise pH and total alkalinity Keep the water balanced all the times, paying special attention to pH and alkalinity.
Alkaline Water Alkaline water is the opposite od corrosive water and usually results in the formation of scale. When th pH or alkalinity levels are too high, sanitizers don`t work effectively and cloudy water can result. Lower pH and total alkalinity by using pH-reducing product. These include sodium bisuffate, sulfuric acid, hydrochloric acid and muriatic acid. Consult your pool and spa supply dealer to find out which product is the bes for your particular situation. Sometime the best way to lower pH is to replace some of the water with the fresh water (assuming the source water isn`t alkaline). Keep the water balanced all the times, paying special attention to pH and alkalinity. If pH regularly drifts upwards, routinely replace some of the water to counter the introduction of bather waste, such as sweat, body oils and sunscreen.
Eye and Skin Irritation Improper pH levels are usually the cause of red, burning eyes, itchy skin and rashes. An insufficient level of sanitizer, which allows the buildup of chloramines, can also be to blame. Test the water to find out whether any water-balanced factors are out of their ideal range. Then shock the pool water to get rid of chloramines. (After shocking, keep the swimmers out of the water until the chlorine residual drops below 10ppm.) Keep the water balanced all the times. Shock the water routinely to eliminate unwanted chloramines.
Odor Spa and pool owners often complain that their water has an unpleasant chlorine odor. It`s a common misconception, however, that this odor is caused by having too much chlorine in the water. On the contrary, a strong chlorine odor means the water is producing chloramines. The presence of chloramines indicates an insufficient level of sanitizer in the water to oxidize or burn away the chloramines. Test the water to find out whether any water-balanced factors are out of their ideal range. Then shock the pool water to get rid of chloramines. (After shocking, keep the swimmers out of the water until the chlorine residual drops below 10ppm.) Keep the water balanced all the times. Shock the water routinely to eliminate unwanted chloramines.
Discolored Water Algae and metals are the most common cause of discolored water. Manganese, for example, can give the water a brown, black or lavender hue. Copper can give the water a greenish tint. Iron can cause a brownish cast. If the problem is algae, follow the guidelines for algae above. If a metal is the culprit, use a sequestering agent to keep the metal in solution. Also use a flocculant to cluster the metal particles so they’re large enough to filter out. Keep the water balanced all the times. If your source water has high mineral content, use a metal remover (available from your pool and spa dealer) whenever you add fresh water to the pool or spa.
Foam When the level of total dissolved solids is high and alkalinity is out of whack, pool and spa water tends to foam when agitated. Some algaecides also cause foaming. This is usually more of a protein in spas than in pools. Use a small amount of defoamer and allow it to circulate for several minutes before adding more as needed. For a Long-term solution, balance, shock, and/or replace some of the water with fresh water. Keep the water balanced at all times. Ask bathers to shower before entering the pool or spa to minimize contaminants in the water. Change spa water completely every two or three months, depending on bather load.
Scum Scum is caused by a combination of contaminants, among them body oils, soaps, cosmetics and lotions. Scum lines around your pools and spa are rarely harmful, but they can be gross Use an over the counter tub and tie cleaner to scrub away the scum. Use as little as possible to minimize the amount of cleaner entering the water. Having swimmers and bathers shower before entering the pool or spa. Use a Scum-absorbing product (available from pool and spa supply stores) that traps scum before it has a chance to cling to the pool and spa walls.
