While shocking and adding algaecide is effective in getting rid of algae, it should not be done together. This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.
If you're adding chlorine to your water, there's a good chance you're adding cyanuric acid along with it. Many chlorine products, like trichlor or dichlor granules or tablets, are known as stabilized chlorine products.
Just make sure that you wait at least 20 minutes after adding chlorine stabilizer (and that it's completely dissolved into the water) before you go swimming. The same rule applies to all other swimming pool water chemicals including adding alkalinity increaser, chlorine, algaecide, and more.
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. Add the stabilizer slowly through the skimmer as per the product's instructions.
You should not add all pool chemicals at the same time. You should also avoid mixing pool chemicals together. Adding chemicals at one time can cause dangerous chemical reactions and serious injuries. In addition, it will make it difficult to balance the pool.
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. It is always best to test first!
If the stabilizer level is too high in a pool, it will lock the chlorine molecules, rendering them ineffective as a sanitizer. This usually happens as a result of using chlorine tablets that contain cyanuric acid.
CYA is a pretty strong acid on its own, so the best way to add it is to dissolve it in a bucket of warm water. Then go all around and pour the solution just inside the edges of the pool. For safety's sake, wear gloves and goggles when you mix it.
There are two methods you can use to dissolve stabilizer into your pool water. You can either add the stabilizer to a pool skimmer box sock and hang the sock in front of the return jet or place it in the skimmer box. Or you can simply mix it in a bucket of water first and dump it into the skimmer box.
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.
Areas exposed to high levels of sunlight should maintain 60 – 80 ppm (parts per million). Pools using an ORP Controller (Oxidation Reduction Potential) such as the AutoPilot Total Control, should maintain 30-50 ppm. Indoor pools do not need cyanuric acid, unless it gets periodic exposure to sunlight.
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.
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.
High CYA will weaken your pool's chlorine and keep it from doing its job. Referred to as chlorine lock, this happens because high CYA overpowers the free chlorine level in the pool. With compromised chlorine you'll soon start seeing issues like algae and cloudy 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.
You should keep your outdoor pool or spa's Cyanuric Acid level at 0-30 parts per million (PPM).
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.
In the pool industry, Cyanuric Acid is known as chlorine stabilizer or pool conditioner. Cyanuric Acid (CYA) is a pool balancing product used to help chlorine last longer. Chlorine, in its natural form, is unstabilized—which means it degrades when exposed to sunlight.
Stabiliser is the generic name given to the use of cyanuric acid (also known as iso-cyanuric acid) or its chlorinated compounds of sodium dichloro-isocyanurate and trichloro-isocyanuric acid. When added to an outdoor swimming pool cyanuric acid bonds loosely to chlorine to minimise its degradation by UV light.
The most important factor though is the size of the pool. You'll need about 52-104 oz of liquid chlorine per 10,000 gallons of water. This amount should get the chlorine level to between 5 and 10 ppm.
Chlorine issues often cause cloudy water. Adding a recommended dose of pool shock to your pool can clear it right up. Poor circulation or filtration can contribute to cloudy water. Make sure your pump and filter are working properly.
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.
Alkalinity Adjusting Chemicals for Pool Start Up
This should be the first chemical that you add to your pool during start-up. This one can really affect the pH level of your pool. Sorting this out first prevents you from ruining your hard work on your pool's pH level by doing it afterward.
