Understanding pH vs Alkalinity in Swimming Pools Pool water chemistry can seem complex for new (and even some old) pool owners. The topic of pH vs alkalinity is possibly among the more challenging aspects. Along with pool sanitation, the relationship between pH and alkalinity is the backbone of pool water chemistry. They influence water clarity,…
Cyanuric Acid level of 60-80 ppm is needed in outdoor salt water pools to protect both Sodium Hypochlorite & Chlorine from the UV rays.
Is your pool looking murky or giving off a strong chlorine smell? Guess what? Maybe Low Pool Stabilizer is the key to the problem! While most pool owners—first-timers or seasoned pros—know that free chlorine is essential for keeping a pool clean and sanitized, not everyone realizes that it breaks down very rapidly under UV radiation…
Powder Shock vs Liquid Shock; the dilemma every pool owner struggles with! The fact is that both are effective in getting the job done. Both Cal Hypo, a powder shock, and liquid chlorine are unstabilized chlorine sources, meaning they will not add cyanuric acid (CYA) to your pool. This article aims to help you make…
Owning a pool is a dream come true for most of us. However, keeping the water clean, clear, and safe can make you wish you had been more attentive in your chemistry class! For example, when the pool water turns cloudy, stubborn scale forms on surfaces, and the chlorine effectiveness drops, the common problem is…
Is Your Pool Alkalinity Too High? Is your pool alkalinity too high? Pool alkalinity needs to be within the recommended range. The recommended range for pool alkalinity (aka Total Alkalinity) is 80 – 120 ppm. KEY TAKEAWAYS Both, pool alkalinity too high and pool alkalinity too low are not desirable conditions as they will have…
Did you know that Free Chlorine (FC) in your pool water gets depleted by 50% every 45 minutes under sunlight, if not protected by Cyanuric Acid? Low Cyanuric Acid can result in healthy FC levels of 4 ppm to drop to dangerously low levels (less than 1 ppm) in two hours or so! Bar Chart…
Are you wondering, “Why is my pool water still cloudy, despite adding more and more chlorine?” The test shows adequate levels of chlorine, but it does not seem to be working! So what’s going on? Most likely, this is a symptom of chlorine lock in a pool. Another related issue is chlorine demand. Chlorine demand…
Pool Calcium Hardness Calculator A pool calcium hardness calculator is useful to figure out how much of calcium chloride to add if calcium harness is lower than target and how much fresh water to add if calcium hardness is higher than target. Pool Calcium Hardness Calculator Pool Calcium Hardness Calculator Pool Volume (Gal): Existing CH…
Muriatic Acid Pool Calculator Please feel free to use the Muriatic Acid Pool Calculator below. Enter the Existing pH Level and the Pool Water Volume (Gallons) to get the Muriatic Acid Dose (oz) to bring the pH Level to a healthy 7.5. (The calculator assumes a Total Alkalinity of 100 ppm and Borax of 0)…
