The Free Chlorine and Cyanuric Acid Relationship
2024年7月20日 · Pool stores and the pool care industry recommend free chlorine levels from 1–3 ppm that are often inadequate for sanitation and algae prevention. Their recommendations are based on outdated information that only focused on individual chemical levels as opposed to the ways that the different chemicals in your pool affect each other.
Maintaining Ph when using a salt chlorine generator
2022年6月28日 · The hydroxyl ion makes this a basic reaction that raises pH, but because the disinfecting chlorine is a weak acid this overall reaction raises the pH by less than a strong base would. Note that there is a small amount of extra base in the form of Sodium Hydroxide (lye or caustic soda) that comes with Sodium Hypochlorite and is there to help ...

Liquid chlorine raising ph?? - Trouble Free Pool
2019年11月30日 · The pH mostly goes back down as the chlorine gets used up. Calcium hypochlorite has more of a pH effect than sodium hypochlorite. In addition, calcium hypochlorite has insoluble dust that clouds the water for hours and leaves precipitate on the bottom of the pool.
Does pH affect chlorine consumption? | Trouble Free Pool
2008年11月5日 · At a pH of 8.0, the overall half-life becomes 25 minutes. Going the other way, at a pH of 7.3, the half-life becomes 41 minutes while at a pH of 7.0 it becomes 54 minutes. So between a pH of 7.0 and 8.0 the chlorine loss rises by a little more than a factor of 2. So, in theory, the breakdown of chlorine from sunlight is somewhat faster at ...
chlorine, PH, test strips vs. drops | Trouble Free Pool
2011年9月1日 · My aqua chem chlorine drops are reading more or less perfect (between 1.5 and 3) on the chlorine level, but then I tested with an Intex test strip which measures Free Chlorine, and it shows the lowest mark (0.2). Which one do I trust? I know they say strips are notoriously inaccurate, but the PH And alk readings seem good on it.

2013年7月16日 · The kits we recommend go quite a bit further in how high they test to, and in the accuracy of the tests, especially the chlorine test. FAS-DPD will accurately test to 50 ppm chlorine, and will give you both the free chlorine (FC) and combined chlorine (CC). Both numbers become very important in keeping your pool sanitized and algae free.

2017年6月6日 · Adjust pH to 7.2-7.8 3. Start your SLAM with the instructions provided in my signature CYA is added with powdered Cyanuric Acid (aka Stabilizer) and pH is Lowered using Muratic Acid. You can calculate the amounts to add using Pool Math. It's important to note that the pH test is not accurate at SLAM levels.
