There are few ways more fun to beat the summer heat than to jump into your swimming pool. If you’re lucky enough to have a pool, then you know how much fun they can be. However, you also know how much work they can be, especially with dirty water. One of the best ways to take your water from dirty to clean is to add a pool clarifier.

Pool clarifier takes 24 hours with a dose of 3-4 ounces of clarifier to be effective and clean your pool. Clarifier works by drawing clumps of algae, dirt, and bacteria towards your filter and breaking them down into manageable pieces. It’s important that you have a good filter and pump when using pool clarifier.

Pool clarifier is an excellent product to add to your pool, but you have to be aware of what to expect when you add it. It’s a slow-acting chemical that takes its time to get the job done. However, it’s extremely effective if you’re willing to be patient. This article will explain what clarifier is, how it works, and when the right time is to use it. Let’s get started!

How Long Does Pool Clarifier Take to Work?

Pool clarifier is a slow-acting chemical that can take 2-3 days to work. The speed with which the clarifier works is largely dependent on how much you add, the size of your pool, and the type of clarifier you use. Certain clarifiers can clean your pool in a single day, while others take several days to work. It also depends on how dirty your pool is, as dirtier pools will take longer to clean.

It’s important that you understand how a clarifier works and what kind you need before purchasing any. For example, some clarifiers draw chemicals to the surface in large groups or clumps for easy removal. Other clarifiers attach to waste products in your pool and force them towards your pool filter. Either way, most clarifiers take several days to clean up your pool.

How to Use Pool Clarifier

If you want to give pool clarifier a try, then here’s what you need to know. Using a clarifier isn’t difficult or dangerous, but you should always follow the instructions listed on your clarifier container. In general, however, most clarifiers can be used as follows.

1. Get Rid of Algae and Large Debris

Pool clarifier has the ability to get rid of many things, but large objects aren’t one of them. If you have leaves, grass, or other solid objects in your pool you should either sweep them up or remove them with a net. While clarifier can get rid of algae eventually it will speed up the process if you remove large clumps before adding clarifier.

2. Check the Acidity or pH level of the pool.

Most pool clarifiers are only effective in water with pH levels between 7.4 and 7.6. Make sure that you know what your level of acidity is before adding and wasting clarifier. You may have to add a pH increaser or decreaser depending on the acidity of your pool. Make sure you do this before adding the clarifier.

3. Know How Much Water is in Your Pool

You also want to know how much water is in your pool so you know how much clarifier you need. It goes without saying, but the more water you have the more clarifier you need. Your clarifier instructions should tell you how much clarifier you need based on the water level of your pool.

4. Read Clarifier Directions and Add Accordingly

Once you know your water level, have the right pH level, and have removed large objects, it’s time to add the clarifier. The amount you add will vary depending on the type of clarifier and the amount of water. However, once you understand what you’re doing, add the clarifier.

5. Run Your Filter to Clear Things Up

Once you’ve added the clarifier, you can go ahead and start up your pool filter. Starting the filter will get rid of the cloudiness caused by the clarifier. It will also help to speed up the cleaning process and get your pool ready for action.

Can You Put too Much Clarifier in a Swimming Pool?

Reading the instructions about how much clarifier to add is extremely important so that you don’t add too much. Adding too much clarifier is harmful to your pool and it will result in problems. The only way to get rid of the excess clarifier is to completely drain your pool and start over. It’s a good idea to start on the low side of how much clarifier you add and increase the dose if necessary.

Why is My Pool Clowdy After Adding Clarifier?

In most cases, clarifier isn’t going to clear up cloudiness instantly. However, if it’s been several hours or a day since you added the clarifier and cloudiness isn’t clearing up, you likely need a new filter or pool pump. It’s important that you keep your filter running nonstop after adding clarifier to get rid of said cloudiness.

Tips About Using Pool Clarifier

Here are a few things to keep in mind if you plan to add clarifier to your pool.

  • Never add clarifier and chlorine at the same time.
  • Make sure that you pH level of your pool is right where it needs to be.
  • Never overdose your pool with clarifier as it could possibly make the problem worse rather than fixing it.
  • Make sure your filter runs non-stop for at least 24 hours after adding clarifier.

Final Thoughts

Pool clarifier is a great product when you know how to use it and in what situations it’s useful. If you’re expecting instant results, then clarifier isn’t the product for you. However, if you’re opening your pool for the first time in the year and don’t plan on swimming for a few days, clarifier is the perfect product.
