Can You Put Too Much Clarifier in a Pool?

A pool clarifier is used to clear up any particles that may be causing your pool to be murky or cloudy. It works by clumping the particles together into manageable-sized chunks that your pool’s filter can handle. While that much is clear for most pool owners, it can be tricky to determine the right amount of clarifier to add, and you might find yourself wondering whether it’s possible to use too much. 

You can put too much clarifier in your pool. Each pool clarifier brand has a specific quantity recommendation for a certain volume of water, and exceeding that threshold can leave your pool murkier than before.

This article will discuss putting clarifier into your pool. It will answer your questions regarding the right amount of clarifier and how to add it correctly, how to tell if there is too much clarifier in your pool, what happens if there is too much in your pool, and how to resolve the issue. Stick around for the details. 

What Is the Right Amount of Clarifier for a Pool?

The right amount of clarifier for a pool can range from 4 oz (29.6 ml) to 32oz (946.4 ml)per 1000 gallons of pool water depending on the specific brand of clarifier used and the water cloudiness and hardness.

Given these variables, you’ll need to check the instructions on your clarifier before use to determine the right amount for your pool. Most brands indicate these details on the packaging, so finding the ideal clarifier quantity for your pool shouldn’t be too hard.

What Happens if You Put Too Much Clarifier in a Pool?

If you put too much clarifier in your pool, the particles will form into too large chunks for the filter to clear, thus enhancing your murky water issue rather than resolving it. 

The purpose of clarifier is to force the particles together into a manageable size for the filter. When you add too much clarifier to a pool, it overworks itself, making the particles too large for the filter. This reaction results in water that appears dirtier than before.That’s why your pool will look more cloudy and murky if you put too much clarifier in it.

Check on your pool frequently during the filtering step to see if it is working correctly. If your pool gradually becomes more transparent, you put in the right amount of clarifier. If it looks unchanged or worse, you put in too much. 

How To Fix Too Much Clarifier in Your Pool

Fixing the issue of too much clarifier in your pool is simple but time-consuming. There are three options for resolving the problem if you added too much clarifier to your pool.

  • Completely drain and refill the pool. This method is time-consuming and could be considered a waste of water.
  • Keep filtering the water until all of the clarifier is gone. This method could overwork your filter or take many days to complete.
  • Partially empty your pool, add clean and balanced water, and filter the remaining clarifier out. This method tends to be the best of both worlds. However, you must ensure that the water you add is balanced, or you risk reinforcing the murky water problem.

How to Put Clarifier in Your Pool


If your pool’s water has a foggy appearance, you probably need to add clarifier. It is important to note that a clarifier is not intended to be used regularly. Its purpose is to remove particles that are dirtying your pool; not be used as a daily or weekly cleaner. 

There are seven steps to putting clarifier into your pool:

  1. Clear the algae and read the clarifiers instructions. It is a good idea to use clarifier at the beginning of pool season to remove any particles that may have accumulated. If you notice that your pool has algae buildup around that time of the year, you’ll need to tend to that issue first because adding a clarifier will not remove algae. Once you have removed the algae, read the instructions on your particular clarifier brand to know the right amount needed for your pool. 
  2. Balance your pool water pH. A Clarifier only works if your pool has a neutral pH balance. You can purchase test kits for your pool to ensure that the chemicals and PH levels are balanced before putting clarifier into your pool. 
  3. Determine your pool’s water volume. The amount of clarifier that you put into your pool depends on the volume of water in your pool. Note your pool’s water volume to ensure you put in the right amount of clarifier.
  4. Add a clarifier. You can choose between a tablet or a liquid clarifier. There are also numerous brand options available. Regardless of the brand or form of clarifier you use, pour or drop it in according to the package directions. 
  5. Filter the water. Once you finish adding clarifier, you will need to turn on your pool’s filter. You must constantly filter the pool water for at least two to three days or until your pool is sparkly clean. 
  6. Clean the pool filter. It is typical for the clarifier and the particles it removes to get stuck onto the pool filter. You will want to clean your filter after using clarifier to make sure it is not blocked up, hindering further use. 
  7. Test and balance your pool. Once the clarifier has completed its job, you will want to retest and balance your pool. Make sure it is back at neutral PH and chemical levels. Also, double-check that your pool’s water volume has not lessened.


You can put too much clarifier into your pool. Read your specific brand of clarifier’s instructions beforehand to see how much clarifier it requires for your pool’s volume of water.

Putting clarifier into your pool is a simple process that takes a few days to complete. You want to ensure that your pool’s water is balanced before adding a clarifier. Allow your filter to clear out the clarifier and particles over a few days. 

If you put too much clarifier into your pool, it will make the water more cloudy, but do not panic. You can easily resolve the issue.
