To keep your pool safe and sanitary, you have to add the correct amount of chlorine to the water. If you have a buildup of chloramines (compounds found in human sweat, among other things) in your pool, shocking the water with pool shock can reduce that buildup and help you enjoy your pool for years. So, here are our top picks for the best pool shocks in 2021 you can order online.

Best Pool Shocks Worth Considering in 2021

HTH 52026 Treatment Swimming Pool Shock - Best Overall

This pool shock is an excellent option for those who want a chlorine cleaner to be used in a swimming pool. This cleaner is effective in killing odor-causing bacteria, so your pool water can remain pleasant to be around. This pool shock can be applied directly to your pool, and it won't fade pools with vinyl liners. It is compatible with all types of swimming pools, including gunite or saltwater ones.

Pool Essentials Treatment 6 Pack Pool Shock - Runner Up

This fast-dissolving pool shock provides all the help you need when it comes to pool safety to remove contaminants. It's also extremely easy to use - just apply it directly to your pool water and watch it go to work. It does the job without imbuing your pool with unpleasant chlorine smells, and can even clear up cloudy water. However, we've seen reports that this product can potentially stain liners, so be careful if your pool has one.

Pool RX 101001 6 Month Algaecide Blue Treats Pool Shock - Honorable Mention

This particular pool shock works a little differently compared to the ones highlighted above; rather than applying it directly to your pool water, these capsules are designed to be dropped into the filter basket of the pump. Once they're placed, a single unit can treat anywhere between 7,500-20,000 gallons of water. It combats algae buildup effectively and can even turn green water into a more appealing clear/blue shade. It can be used for salt pools, as well, so you don’t have to worry about it being too harsh on the water.
