How Much Liquid Chlorine to Shock a Pool With Algae - Get Your Pool Summer-Ready

How much liquid chlorine to shock a pool with algae will depend on how green your pool is; whether it is light, medium or dark green.

How to Prepare for Shocking

Here is the step by step process for preparing your pool for this treatment. Keep in mind that you should do this in the evening so that you get optimal results.

Step #1: Clean Your Pool

You have to make sure that your pool is completely clean and doesn’t have leaves or debris in it. Any dust or debris floating on the top or on the bottom can interfere with this process. Chlorine can attack the organic matter more rather than the algae.

Step #2: Lower the pH Level

Calcium products have a better efficacy when it comes to lower pH level. So, add a bit of acid to the pool for adjusting the pH level to 7.2.

Step #3: Assess the Algae in Pool

You have to now determine the severity of the algae in your swimming pool. You can assess this by the color of the pool. Light green means mostly clear with visible patches. If the color of the pool is medium green, then the algae is in all areas. Dark green means the algae deposit is very thick.

Shocking Treatment for Algae

After cleaning the pool and adjusting the pH level, you have to proceed further to add the chlorine into the pool. Most of the shock treatment packages will direct you to add 1 lb. (1 bag) of shock per 10,000 gallons of the pool water. This can be fine for any normal conditions. But if your pool is severely attacked by algae, then you will need to take other steps.

The best technique for the pools that are severely attacked by algae is to provide shock treatment unless until the water of the pool starts to turn blue-ish. Here is the chart that you have to use for shock treatment based on the color of the pool.

For light green pools, use 1 lb. of shock treatment per 10,000 gallons of water. So, for 25,000 gallons of water in pool, use 2.5 lb. of shock treatment.

For medium green pools, use 2 lb. of shock treatment per 10,000 gallons of water. So, for 25,000 gallons of water, use 5 lb.

For dark green colored pools, it is better to use 3 lb. per 10,000 gallons of water. So, for 25,000 gallons of water, you have to use 7 lb.

Conclusion

So, if you had a question in your mind regarding how much liquid chlorine to shock a pool with algae, you probably have now gotten the answer. You’ll have to calculate the amount of water you have in your pool and determine the color of the pool.
