Using Conditioner in Your Pool

There are plenty of chemicals and routine maintenance when it comes to owning a pool. But just because you pour chemicals into a pool doesn’t mean that’s all you need to do to keep it clean. In fact, owning a pool means you must have all the necessary water and chemical levels well balanced. We’ll be going over one of the most overlooked chemicals that does a lot to help with your pool and its existing chemicals. We’re referring to pool conditioner.

Pool Conditioner Explained

Conditioner? Cyanuric acid? Pool stabilizer? What does this all mean? In fact, all three mean the same thing. Cyanuric acid is a type of chemical compound called triazine, which means it contains three nitrogen atoms and three carbon atoms. Still confused? Let’s break it down. Cyanuric acid is a pool stabilizer because its sole function is to stabilize the water in your pool for as long as it can. It basically helps keep your water clean for longer.

How Pool Conditioner Works

Not only will chlorine burn off when sanitizing water, but it can also be dissipated by the sun’s UV rays if not protected. This protection is from cyanuric acid (CYA) in your pool that is provided by Leslie’s Conditioner. If there is no CYA in the water, up to 90% of your chlorine may burn off in 2 hours. Ideally, your CYA level should range from 30–50 parts per million for pools using tabs and 80-100 parts per million for salt pools.

How Do You Add Conditioner to a Pool

Adding Conditioner to your water is a process that is not complicated, but requires you to follow additional instructions carefully. Conditioner takes days, rather than minutes, to dissolve, unlike many chemicals. It also has a tendency to expand slightly once exposed to water. Because of this, the application process is different compared to adding a chemical like Soda Ash.

Follow these Directions When Adding Conditioner

  1. Determine the correct amount of conditioner needed to reach your intended target of between 30-50 parts per million (ppm) or 80-100 parts per million (ppm). Your cyanuric acid levels can be tested using a home test kit or visiting a local Leslie’s.
  2. Shut the system off.
  3. Remove the skimmer and filter basket from your system. Baskets can halt the flow of conditioner into the filter once it’s added.
  4. Replace all lids that were removed to take the baskets out of your system.
  5. Turn the system on.
  6. Add the required amount of conditioner into a bucket of pool water and mix it into a slurry.
  7. In small increments, add the slurry into the skimmer. Once you notice the conditioner disappear, add the next small dose. Continue this until all of the mixture is gone from the bucket. By adding conditioner this way, the product will get stuck in the pool filter, allowing it to safely dissolve into the water without staining.
  8. Continue running your pump for one hour after the addition of conditioner.
  9. Replace all baskets in your system.
  10. At night, make sure to run your system for at least 8 hours to help the conditioner dissolve.
  11. Avoid backwashing or cleaning your filter for 48 hours after the addition of this product. Because it takes multiple days for conditioner to dissolve, if the filter is cleaned only 24 hours later, some product will be removed with it.
  12. Retest your water in 7 days to ensure your CYA is within the necessary range.
