The time it takes for cyanuric acid to dissolve is 2 to 5 days.
For liquid stabilizer, you only need to leave it on for a few hours to mix through. For granular cyanuric acid, leave the pump on for 48 hours. Then run the pump for a minimum of 4 hours per day for a week (you should be doing this anyway).
When Is It Safe To Swim After Adding Cyanuric Acid? As a general rule though, you can swim in your pool within 20 minutes of adding cyanuric acid. Make sure you have the pump on when you add it so that it mixes in the water. It's always best to check the manufacturer's instructions though.
Test strips are the easiest way to test cyanuric acid in your pool. Cyanuric acid is raised by adding chlorine stabilizer containing cyanuric acid. The only way to lower cyanuric acid is by replacing water.
When the product reaches the filter, there may be a temporary increase in filter pressure which will dissipate as the product dissolves. You may swim immediately if Stabilizer was added through the skimmer, otherwise wait 12 hours to swim until all product in the pool is dissolved.
We recommend adding Acid weekly! Adding a little and often is better for your water and can actually save you money overtime. Large doses over longer periods of time take a larger portion of your 'Total alkalinity' away.
It 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. It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours.
To add cyanuric acid to your pool:
Add a dose of stabilizer to the bucket. Check the product instructions for the right dose based on your pool size. As a general rule, add 13 ounces of cyanuric acid to gain 10 ppm of CYA in a 10,000-gallon pool. Remember, your CYA should be between 30 and 50 ppm.
Recent CDC research presented at the October 2015 World Aquatic Health Conference demonstrates that even at cyanuric acid levels as low as 10 to 20 ppm, the current recommended remediation protocol is not adequate to inactivate the necessary 99.9 percent of Crypto in pool water.
Answer: Cyanuric acid shouldn't be at Zero for an outdoor swimming pool because chlorine will deplete faster in hot and humid weather, leading to cloudy water. If your FC is at normal level of 3ppm, raise Cyanuric acid level to 40 ppm and you will reduce chloramine levels that make your water appear cloudy.
Saltwater pool manufacturers recommend maintaining cyanuric acid levels around 60-80 ppm. This is a bit higher than the 30-50 ppm range recommended for non-saltwater pools. And if you live in an area where your pool gets a lot of direct sunlight, you may even consider bumping your cyanuric acid up to 80-100 ppm.
You should keep your outdoor pool or spa's Cyanuric Acid level at 0-30 parts per million (PPM).
Clearly, when cyanuric acid is in the water, it overpowers pH in terms of controlling chlorine strength.
Before getting in
Don't swim or let others swim if sick with diarrhea. Shower for at least 1 minute before you get into the water to remove dirt or anything else on your body.
TEST IN THE MORNING
If you are having chlorine issues in your pool, the best time to get a water sample is in the morning. Even with proper amounts of chlorine stabilizer, chlorine will burn-off during the day. Testing in the morning will give your water a chance to circulate all night and avoid the sun's UV rays.
Along with balancing the pH levels of your pool water, muriatic acid is strong enough to kill mold, remove rust stains, get rid of calcium deposits, and clean the surfaces of your pool.
According to Clean Pool and Spa, you should wait no less than two hours before swimming in a pool which has been treated with muriatic acid. According to the website, "If you pour muriatic acid in the pool and swim within 10 to 15 minutes you might get a 'hot spot' of acid that can burn you."
If there is a problem with the chlorine, pH or other chemical levels in your pool, adjusting those levels can be enough to correct the cloudiness. For example, if your pool water is too basic, you can add hydrochloric acid or sodium hydrogen sulfate to lower the pH.
If you do add too much muriatic acid, your pH levels can dip dangerously low, and your pool water can cause rashes and eye irritation. Low levels of pH can also damage metals in your pool like ladders, railings, screws, bolts, and other important equipment.
Baking soda is the best way to raise total alkalinity with minimal effect to pH and cyanuric acid.
Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.
Although there are no known adverse health effects associated with high CYA concentrations, most health officials usually limit CYA levels to 100 ppm. Some states recommend a lower level for spas, and some jurisdictions ban the use of CYA altogether.
For diluting, you don't have to use an exact science, but basically, if your cyanuric acid level is 5% too high, then you need to remove about 5% of the pool water.
Open your pool under normal procedures, and let the filter run with its normal amount of chemicals. When all the other chemicals, such as chlorine. pH and alkalinity, are balanced, add the chlorine stabilizer. Add the stabilizer only after the filter has been backwashed to ensure it is cycled through a clean filter.
Yes, at the same time is fine. Those two don't affect each other at all.
