|Alkalinity is often overlooked in pool water testing and is an important aspect in proper water chemistry. The experts at Pool Supply Unlimited have serviced thousands of swimming pools and know what it takes to obtain crystal clear, balanced water. Follow our simple program and we will guarantee your water will be algae free.
Recommended alkalinity for swimming pools is 100-120. Our alkalinity booster is the purest chemical on the market today and will boost your alkalinity without adding unwanted inert chemicals.
At Pool Supply Unlimited we have seen the damage that unbalanced water can cause when in contact with concrete, grouting and metals like copper and steel. Water can either corrode such surfaces or deposit a white film or crusty, coarse substance called scale. The two types of unbalanced water conditions are corrosive and scaling.
Corrosive water is "aggressive" and attempts to dissolve concrete and metals, pitting concrete and destroying steel filters and copper heat exchangers. A tell-tale sign of corrosive water is staining, which is the deposit on the pool's surface of colored metal salts of iron (brown) or copper (blue/green/grey/black). Scaling water does the opposite. It attempts to deposit or precipitate calcium carbonate out of solution, causing a white film or rough, unsightly deposits on pool surfaces, and possibly plugging the filter and circulation piping.
Pool Supply Unlimited can help keep your pool water in balance to avoid unnecessary and costly repairs. This is accomplished by controlling the parameters that determine water balance. The factors are pH, calcium hardness, total alkalinity, temperature and total dissolved solids (TDS). The main focus should be on pH, calcium hardness and total alkalinity.
Total alkalinity is the measure of the ability of water to resist changes in pH. Total Alkalinity acts as a "buffer" to the pool water from wide variations in pH. It is the governor or pH and is a major factor that affects water balance.
A buffer is a chemical system that resists change when acid (pH decreaser) or bases (pH increaser or alkalinity booster) are added to the swimming pool. Water that has no buffering ability has a very low alkalinity and is subject to rapid swings in pH levels when small amounts of acid or base products are added. The result is highly unbalanced water that can cause damage to light rings, stainless steel ladders, copper heat exchangers and concrete pool surfaces.
Pool Supply Unlimited has many varieties of test kits that will aid you in maintaining the proper balance of alkalinity in your swimming pool.
