Blue Horizons Total Alkalinity Reducer 5 Litre

Product Information

Baking soda ( sodium bicarbonate) raises total alkalinity while having almost no impact on pH, so it’s perfect for situations where you need to raise alkalinity in isolation…. like this one. It makes your water cloudy. As pH rises and calcium falls out of solution, it floats around in your pool water causing it to appear murky or cloudy, especially with higher calcium hardness. If you’re a pool operator, you probably already know that pH fluctuates. In particular, it naturally rises. Correcting pH is almost always accomplished by lowering it with acid or injecting CO 2. Let’s not forget rainwater, which can dilute the water and therefore lower the concentration of total alkalinity. The same applies if you drain and refill the pool, depending on the total alkalinity of the fill water used.

Keep reading for a complete guide on what affects your pH and how to lower pH in a pool with pH decreaser or muriatic acid. How Do pH and Total Alkalinity Affect Each Other? Aside from that, the cyanuric acid in stabilized forms of chlorine (including most tablets or granular chlorine) also contributes alkaline substances to the water, and these will inflate your total alkalinity reading.

Alkalinity cannot be measured in real-time with probes, at least with today's technology. Perhaps someday it will be possible, but for now, we must rely on titration or color-change on a test strip. The most common titration is with liquid reagents, where each drop is counted as it neutralizes more and more of the sample until the color changes. Follow your test kit manufacturer's instructions. For example, stabilized trichlor chlorine has a pH of around 3. So when you use trichlor chlorine to sanitize your water, you make it more acidic. But because it’s stabilized, it contains cyanuric acid. And that buffers the acidity in your pool water. Buffered acidity can raise the alkalinity.

Another way to visualize pH is an H 2O molecule of water. When a Hydrogen ion (H +) dissociates or breaks away, it leaves behind a Hydroxide ion (OH -). The H + is the acid, and the OH - is the base. So when you see substances that have an (OH) in them, such as sodium hydroxide (NaOH), or calcium hydroxide (Ca(OH) 2), you know it will have a high pH. The roles of pH in water chemistry Method One: Turn off the pool’s pump and add the muriatic acid in a small, steady stream directly into the deep end of your pool. This ensures the acid will go directly to the bottom, rather than floating around at the pool surface. Then turn your pump on and let it circulate the acid through the water. If you want to increase total alkalinity in a swimming pool, you need to know the gallonage of the pool and your pH. It helps to have an accurate dosing calculator. Raising alkalinity is as simple as adding sodium bicarbonate to the water. Then, add the reagents into the water. After adding the reagents, make sure to add a small amount of chlorine neutralizer. This is one way to get the correct reading of the total alkalinity in your pool.

After that, go ahead and test your water again. You should see that your pH level is now very low (don’t panic, this is normal) and your alkalinity is about where it needs to be. Then, leave it for two hours to let the chemicals dissolve fully in the water. After that, you can turn on the water pump. Keeping your pH level within this range is extremely difficult without total alkalinity keeping guard, as it provides a buffer to counteract small changes in the water chemistry.

So when you're maintaining your water, keep in mind that higher TA will mean more acid required to reduce pH, and it will also encourage pH to rise higher. Lower TA will mean less acid required to reduce pH, and will limit how high pH can go. We definitely want TA in our water, but we do not need as much as the textbooks say in some cases...it depends on the time of year (water temperature in particular), and the type of primary chlorine. Acid chlorine like trichlor needs more alkalinity, whereas salt chlorine systems, liquid chlorine and cal hypo can be fine with less than 80 ppm TA, provided you maintain LSI balance.We elaborate on this thoroughly in other articles listed above. Technical explanation: The more of your water’s surface area is exposed to air, the faster it outgasses carbon dioxide. Since carbon dioxide is acidic, reducing the amount of this substance in your water naturally leads to a rise in pH.

Pool alkalinity, total alkalinity, or simply TA, measures your water’s ability to resist change in the pH level. If you want to lower the pH in your pool, you need to use a low pH chemical, otherwise known as an acid. And yes, we are aware we are recommending lower total alkalinity levels than the textbook standards (provided your LSI remains balanced, so keep water temperature in consideration!). The lower alkalinity will allow you to contain pH more effectively. How alkalinity is measured Knowing how important pH is to your pool chemistry, it’s unsurprising what happens when it comes out of balance.

The ideal level for total alkalinity in a swimming pool is between 80 and 120 parts per million (ppm). This provides enough of a buffer to your pH without making it too difficult to adjust when you really need to. Health departments care mostly about water being maintained with adequate disinfection speed. So of the three reasons cited for maintaining a pH between 7.2 and 7.8, by far the most important to the health department is chlorine strength (%HOCl). When your water becomes too basic, however, it leads to cloudier water, weakened sanitizer, scaling of pool surfaces, and just general discomfort on your skin and eyes.The most effective and easiest to control, at least in terms of raising your total alkalinity, is bicarbonate. You can add bicarbonates to your water by simply adding sodium bicarbonate (baking soda).
