pump/motor, and the general plumbing. Look on the ingredient label. In the world of pool chemical, cyanuric acid is often called a pool stabilizer which is produced in granule or liquid. However, other experts disagree, saying that at least a small amount of CYA is good for indoor pools, especially those that may be surrounded by windows that let in a lot of sunlight. That being said, draining and/or diluting water is still the most economical way to lower CYA levels in a pool. Figure 1 below illustrates this: Figure 1: The relationship of chlorine’s “staying power” and CYA, Figure 1 shows us that roughly 20-30 ppm of CYA is enough to give us 95-98% protection from sunlight in the first hour, assuming this chart is accurate.

I know you’re starting to see dollar signs dance in your eyes, thinking of all of the chlorine you’re going to have to buy to keep up with the sun’s depleting effects. We recommend you consult a local pool professional before acting.

Cyanuric acid is used in swimming pools to lower the rate of photochemical reduction of chlorine, hypochlorous acid, and hypochlorite ion. After that, if you use stabilized chlorine each week, you’re adding a little CYA every time. All you need to know is the higher your CYA, the lower your LSI. Another very reliable kit, this one contains enough solution to perform several more tests than the Blue Devil kit. Cleanup Expert Advice. Each time that you add chlorine after that, you’ll be testing chlorine levels and keeping your cyanuric acid levels in-check. The Committee that writes the Model Aquatic Health Code (CMAHC) released a 2016 update that indicates an upper limit of CYA in pools with a fecal incident. Determine if you need to add cyanuric acid to your pool. For every 10,000 gallons, you’ll need about 4 pounds of CYA per every 30 ppm it needs to increase.

It stays in your water for a long time. Perhaps there are valid reasons—costs, structural risks, labor, environmental concerns—for not draining high CYA pool water. On the flip side, like we talked about earlier, if your CYA levels are too high, it will diminish the effects of the chlorine almost completely. If not, most cartridge filters have a drain plug on the bottom of the filter housing that you can easily attach a hose to. You might see it called trichlor when it’s mixed with chlorine tablets or sticks and dichlor when it’s mixed with pool shock. Cyanuric acid levels are raised by adding pool stabilizer. Water. Il doit être entre 7.2 et 7.4. As if CYA's impact on chlorine were not enough of a reason to keep its levels to a minimum, there is more. Just look at how much chlorine (and acid to re-balance pH) is required to achieve the desired sanitation result.

These products have simplified instructions on the packaging. It takes a while to drain a lot of water through a small hose though.

Chemically speaking, sodium dichlor is made up of one cyanuric acid molecule with two chlorine atoms and one sodium atom. Dissolve it in your bucket and pour it around the edge of your pool.
