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.
To achieve the recommended amount of 30 ppm, add one pound of CYA stabilizer per 4,000 gallons of water. The chemical is a strong acid so wearing gloves and goggles when preparing the solution is well-advised. Once the required amount of stabilizer has been calculated, mix it in a five-gallon bucket of warm water.
It's also included in chlorine tablets or sticks (called trichlor) or shock (called dichlor). When they're mixed together in shock or tablets, the resulting product is called stabilized chlorine. Typically, pool owners won't need to add any extra stabilizer separately if you're using one of the combination products.
Because of the importance of stabilizer, there are unfortunately no alternatives. If you stopped using it, you would continually struggle with chlorine levels, bacteria, and algae. We understand that all the chemicals needed to keep a pool looking healthy can add up and become costly.
If your CYA levels dip too low, your chlorine will be completely gone in a few hours and your swimming pool will become susceptible to bacteria and algae growth. If the pool stabilizer levels get too high, however, it overpowers the chlorine and makes it less effective.
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. Most products require 1 lb. of stabilizer per every 3,000 gallons of water.
With pump running, remove skimmer lid and slowly pour the required amount of stabilizer granules into the pump system. ADD IN SMALL AMOUNTS! Do not put more than 1 pound of stabilizer* into the skimmer over the course of an hour as the particles could jam your pump basket.
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.
What level should it be at? Stabilise levels in the pool should be between 30-50ppm. As a rule of thumb it's best to test for stabiliser (CYA) once a month to maintain a correct level. Roughly add 2kg per 40,000L to raise the stabiliser level by 30ppm, but always read the guide on the packaging.
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.
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.
Baking Soda is used for raising the total alkalinity of the pool, which is the key to keeping the ph in balance. It's not a stabilizer.
Liquid chlorine and granular shock have the same active chemical that sanitizes your pool, what changes is the strength and the way you use it. Liquid chlorine is less costly, unstabilized and comes in liquid form. Granular shock is stabilized and comes in a solid form that dissolves in your pool.
Clorox® Pool&Spa™ XtraBlue® Chlorinating Tablets go the extra mile to help maintain healthy pool water. These multi-functional tablets work hard to keep your water clear from both bacteria and unsightly algae. Each tablet dissolves slowly and contains stabilizer for a long lasting clean.
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.
In general, about 13 ounces of granular stabilizer will raise the CYA level of 10,000 gallons of water by 10 parts per million. Add the stabilizer to the skimmer basket while the pump is running, and keep the pump running for 24 hours after you add the stabilizer.
Baking powder is also a chemical leavener that is made up of baking soda, a dry or powdered acid (like cream of tartar) and an inert stabilizer (like cornstarch), which works to absorb moisture and keep the baking soda and acid from interacting before it's time.
What can you use instead? Bromine — considered a safe substitute for chlorine. Looks for BCDMH tablets, which are typically 66% bromine and 27% chlorine. If unable to find, you can use just bromine but it may leave the water a dull green color.
Stabilizer, or cyanuric acid, is a _very_ weak acid, it can takes a few days to completely dissolve in pool water, it will not however ruin or damage your liner. Sprinkle the stuff on the water surface, let it drop to the floor and in a few days it'll be all gone.
Adding Stabilizer
Some suppliers suggest adding granules via the skimmer so that they dissolve in the filter, releasing stabilizer to the pool over several days. Pool owners should avoid backwashing the pool for three days after adding stabilizer, allowing time for the product to fully dissolve and circulate.
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
