Does Cal-Hypo raise CYA?
• Cal-Hypo (calcium hypochlorite), will not raise CYA but will raise the calcium (CH) level Thanks! The brand I have is "chlor brite", which is indeed used for pool shock. You'd think the guy at the pool store would know this?! Sounds like liquid is the only option for me since water in CA is already hard as it is.
Does chlorine raise CYA?
Of the two forms of chlorine that will raise the CYA level (trichlor being the other), dichlor is the worst offender. It will raise the CYA level almost as much as it will the FC level.
What happens if you use calcium hypochlorite every day?
If that wasn’t bad enough, using calcium hypochlorite every day will eventually raise your calcium hardness levels way above the recommend range, not to mention the complications surrounding daytime use considering it doesn’t contain any pool stabilizer.
What is calcium hypochlorite chlorine?
What is Calcium Hypochlorite? Calcium hypochlorite—or what most people just call “cal hypo”—is one of various types of chlorine you can buy, and it looks exactly how you’d expect pool chlorine to look.
Does calcium hypochlorite raise cyanuric acid?
In addition to raising available chlorine, cal hypo boosts pH, alkalinity and calcium hardness (CH) levels. Trichlor has the opposite effect on pH and alkalinity — reducing it. And where cal hypo affects CH, trichlor increases cyanuric acid (CYA).
Does calcium hypochlorite contain CYA?
Cal hypo does not contain stabilizer (cyanuric acid), though it can be stabilized toward sunlight in recreational water through the use of cyanuric acid. You can buy it in slow dissolving tablet forms, or more rapidly dissolving granular forms, depending on your needs.
What are disadvantages of using calcium hypochlorite to keep a home swimming pool clean?
The main drawback in using calcium hypochlorite is the need to store the chemical properly to prevent any possible contact with heat or moisture. If calcium hypochlorite is exposed to even small amounts of either, it can cause violent explosions, fires and the release of highly toxic chlorine gas.
Does sodium hypochlorite raise CYA?
Also, sodium hypochlorite will not contribute to an increase in calcium or cyanuric acid. It remains one of the purest and simplest formulas for the disinfection of bacteria and the prevention and removal of algae in swimming pools. Brief history of liquid sodium hypochlorite its other uses etc.
How do you chlorinate a pool without raising CYA?
Non-Stabilized Chlorine Options to Trichlor TabletsLiquid Chlorine. Regular bleach, or sodium hypochlorite – contains no cyanuric acid. ... Salt Chlorinator. Salt Chlorinators, aka salt chlorine generator will create most of the chlorine needed for your pool. ... Cal Hypo Tablets. ... Go Low Chlorine. ... Go Tablet Free.
Does liquid chlorine lower cyanuric acid?
Most cyanuric acid reducers won't work as effectively in an over-chlorinated swimming pool. Check the chlorine level in your pool with a water test kit or test strip. If the chlorine levels are above 5.0 ppm, leave the pool exposed to sunlight or use a chlorine neutralizer to lower it.
Which is better for Pool sodium hypochlorite or calcium hypochlorite?
When buying disinfectant for your pool, you'll probably most commonly see cal-hypo. But if you live in a region where calcium deposits are an issue, sodium hypochlorite might be the more effective way to go. Just make sure that you're testing all your levels frequently and using it with a stabilizer like CYA.
How soon can you swim after adding calcium hypochlorite?
2-4 hoursIt is recommended to wait at least 20 minutes to an hour after adding water balancing chemicals. You should wait 2-4 hours (or one full cycle through the filter) to swim from the moment you use calcium chloride in your pool.
What pool chemicals contain cyanuric acid?
Dichlor and trichlor contain both chlorine and cyanuric acid so it is not necessary to add cyanuric acid to the pool water. Dichlor usually comes in a granular form and is marketed for the residential swimming pool market.
How do you keep CYA from getting high?
The only effective way to lower your CYA is to partially drain your pool and refill it with fresh water. If you think your cyanuric acid is too high, the first step is to stop adding more CYA or stabilized chlorine to your pool before diluting your water.
What does calcium hypochlorite do for pool?
When the cal hypo is poured into the pool, the chlorine compounds will encounter the microbes and begin to disturb their functions. It does this by attaching to the enzymes of the microbes' cells. Soon it will ultimately kill the bacteria by disrupting all the inner workings and destroying the cell walls.
What causes CYA to drop?
When bacteria get going consuming CYA, it tends to happen fairly quickly. In addition to water dilution, CYA can also drop by being slowly oxidized by chlorine, but that usually takes months to notice. It's possible that some chemicals in the water may make that reaction more rapid, but we don't know for sure.
Does Shock Affect Cyanuric Acid?
How often do you Shock your pool? Shocking your pool need not wait till your pool has gone green with “algae bloom” and you do not have an option. During the pool season, you should shock your pool every week. But, Does Pool Shock Affect the Cyanuric Acid (CYA) level?
How do you Shock a Pool without Raising CYA?
If a Pool Shock is stabilized, it will have CYA. Stabilized Pool Shocks are convenient but not at all necessary.

What is trade % in chlorinating liquid?
Your calculations are essentially correct except that chlorinating liquid goes by Trade % which is not the same as Weight % of sodium hypochlorite as found in bleach, for example. Trade % is the Volume % of Available Chlorine which is the Weight % of Available Chlorine times the density of the liquid.
Does aeration lower pH?
The aeration causes carbon dioxide to outgas which makes the pH rise and in spas where the water is hotter it also causes outgassing of hypochlorous acid itself (so some of it doesn't breakdown to lower the pH). Finally, the graphs that are typically shown in CPO and similar courses are incomplete.
Does chlorine build up over time?
While the Free Chlorine (FC) will get broken down (converted to chloride -- salt) from sunlight and oxidizing organics (mostly urea/ammonia) and killing algae, bacteria and viruses, the Cyanuric Acid (CYA) and Calcium Hardness (CH) do not go away and instead build up over time.
Does CYA affect pH?
When you add chlorine to a pool with CYA, the pH goes up more (or with acidic chlorine, the pH drops less) than it would if you added the chlorine in a pool with no CYA.
Why does my pool water drop in CYA?
This can be due to water evaporation or a large splashout that requires refilling the pool, or even if it rains.
What is the ideal cyanuric acid level for a pool?
The ideal range for cyanuric acid in your pool is between 30 and 50 ppm (parts per million). Anything lower and you will likely see some undesirable side effects when it comes to your water chemistry. Let’s talk about why this happens, why it matters, and how to raise cyanuric acid (CYA) in your swimming pool. Skip to:
How to add chlorine to a pool?
Here’s how to do it: 1 Start by balancing and testing your pool water. 2 Figure out how much chlorine you need to add to the pool so that it reaches between 1 ppm and 3 ppm. 3 Safety is priority so always use chemically resistant rubber gloves and protective eyewear when handling chlorine. Long sleeves and pants are a good idea too. 4 If using granules, add the measured amount of granules to a 5 gallon bucket of water and mix with a stir stick. Fully dissolve it so that no granules attach to the pool walls and damage the pool finish. Walk around the perimeter of the pool and pour the solution in. 5 If using liquid chlorine, you can pour the measured amount straight into the pool or skimmer. Be careful it doesn’t splash on the walls. You may want to dilute it by adding it to a bucket of water first. 6 If using pucks, add them to a chlorine dispenser or the skimmer basket. Be aware that some baskets can be damaged by the chlorine sitting in them for long periods of time. 7 Retest the water after it has fully cycled (takes about 6 hours) to get an accurate reading of the chlorine and CYA in the pool. Adjust/add more if necessary.
Why is my pool green?
A green pool is caused by a lack of clean water, which leads to algae growth. Depending on your situation, you can also develop pink slime or black algae, both of which leave your pool a nasty shade of ugh! Water chemistry imbalance. With low CYA not protecting chlorine, the chlorine level drops.
What is chlorine bind?
When free chlorine binds to ammonia pollutants such as sunblock, sweat, and urine in the water, it becomes combined chlorine (chloramines). Not only is this form of chlorine a much less effective sanitizer, it also kicks up a pungent “chlorine smell”.
What is stabilized chlorine?
Stabilized chlorine (sodium dichlor, trichlor) is available in either powdered granules, liquid, or puck/tablets. All are easy to add to the pool and can be done a few different ways.
What to use to handle chlorine?
Safety is priority so always use chemically resistant rubber gloves and protective eyewear when handling chlorine. Long sleeves and pants are a good idea too. If using granules, add the measured amount of granules to a 5 gallon bucket of water and mix with a stir stick.
Does Shock Raise Cyanuric Acid?
You need to shock your pool every week in the season to ensure it is well sanitized and disinfected. Regular chlorination is of course important but shocking your pool is the “fast and furious” way of killing off most of the germs, bacteria and algae. But Does Shock Raise Cyanuric Acid Levels?
Dichlor Shock and Cyanuric Acid (CYA) Relationship
The full name of the Dichlor shock most commonly used is sodium dichloro-s-triazinetrione. Dichlor is a compound of Chlorine and Cyanuric Acid (CYA). So using Dichlor shock will naturally increase both Chlorine and Cyanuric Acid (CYA) levels.
Unstabilized Chlorine Shock and Cyanuric Acid (CYA)
Chlorine is the “sanitizer” and Cyanuric Acid (CYA) is the chlorine “stabilizer”. Cyanuric Acid (CYA) protects the chlorine from being broken down by the UV rays of the sun.
Chlorine Free (KMPS) Shock and Cyanuric Acid (CYA)
The key ingredient of Chlorine Free Shock or Non Chlorine Shock is Potassium Monopersulfate (KMPS). KMPS is a powerful oxidizer that will get rid of organic contaminants and clear up the pool water pretty fast.
Do Chlorine Tablets Raise Cyanuric Acid?
Chlorine tablets are generally used for regular chlorination so that the pool chlorine level can be maintained at the optimal level of 2-4 ppm. Trichlor tablets and Cal Hypo tablets are most common.
