How Do I Convert My Pool From Baquacil to Chlorine? 

Although we do not recommend biguanides, we understand that there are special circumstances that might warrant a family to choose this option over chlorine. Still, biguanide pools are something we do not see very often but when we do, pool owners have the same question:

How do I convert my pool from Baquacil to chlorine? 

If you find yourself in this same predicament, don’t fret. INYO put together a step by step solution that helps pool owners convert their pool back to chlorine.

1. No More Biguanides

First, if you no longer want to use biguanides- stop putting it in your pool. Let the biguanide levels fall to zero. Depending on the size of your pool, this might take a few days. However, if this process takes longer than expected, we recommend treating your pool with non-biguanide algaecide. This helps prevent algal blooms from forming around your pool. Additionally, we recommend brushing your walls to help prevent algae.

In short, stop adding any biguanides to your pool. 

 

2. Clean Your Filter

Once your biguanide levels reach zero, focus on cleaning your filter. Also, it’s normal for the color of the water to change. Even though your water tests zero for biguanides, there may be residual biguanide in/on your liner or pool equipment. Don’t worry, though, the color change is only temporary and works itself through.

Sand Filters: Change the sand in your filter.

Cartridge Filters: Replace or chemically clean your cartridges.

D.E. Filters: Clean the inside of the tank, grids or fingers, remove and replace D.E powder,  

 

3. Adjust the pH Levels

Next, make sure you test your chemical levels with a new test kit BEFORE adjusting your pH levels. Ideally, your pH levels should be between 7.4-7.6 ppm.

To increase your pH levels, use a pH increaser. If after testing your water your pH and alkalinity levels are low, you can add alkalinity to increase both simultaneously.

 

4. Shock Your Pool

The next thing you want to do is shock your pool. Make sure you purchase non-chlorine shock. DO NOT use any other kind of shock during this step.

Add 4 pounds of non-chlorine shock per 10,000 gallons of water. (ie. If your pool is 30,000 gallons, you need 12 pounds of non-chlorine shock.) Again, don’t fret if you see your water beginning to turn clear green. That is common.

 

5. Re-Adjust Your pH

After a few days, check your pH levels again to make sure it is holding. Again, the ideal level for pH falls between 7.4-7.6 ppm. Also, don’t forget to keep an eye on your filter. Actively clean out your filter to avoid backup.

 

6. Add Chlorine

Finally, your pool is ready for chlorine. Be careful though, you don’t want to just throw chlorine in your water. Slowly introduce chlorine back into your water. If you own a chlorinator, start by adding a single chlorine tablet. Once it dissolves and you water seems OK, continue to add more tablets to your chlorinator. Continue to increase your tablets until your chlorine levels reach 1 ppm.

Once your levels reach 1 ppm, you can continue regular chlorine maintenance.

In short, slowly add chlorine into your pool until your chlorine levels read 1 ppm. Then, continue your normal chlorine regiment. 

What Your Water Looks Like

I mentioned earlier in the article that your water is bound to change in color. In fact, the array of colors is probably one of the only exciting things you see during the transition. Below are pictures that were taken of a pool while converting back to chlorine from Baquacil. I pulled these pictures from our friends over at www.troublefreepools.com

  1. I’m making the switch to chlorine. Thanks for the advise. I’m starting to get balls of white slimy stuff in the pool. Is that the bacqacil reacting to the chlorine?
