How to Put in Pool Chemicals?

The fact is that your swimming pool needs chemical additives to keep the water, clean, clear, and safe. Even if you skimmed, scrubbed and vacuumed the pool every day, you’d still need to add chemicals to maintain the proper water chemistry. But what’s the best way to deal with these chemicals? If you’re looking to learn how to put in pool chemicals, we’ve come up with a list of considerations to help with your pool maintenance duties.

Safety First

Even though you’ll eventually be swimming in a solution containing your pool chemicals, before they’re added to the pool, you’re dealing with concentrated chemical substances that could cause you physical harm. For this reason, proper safety precautions should always be taken. When dealing with powdered chemicals you should take note of the wind patterns and consider using goggles if it’s very windy. You might also consider wearing gloves and protective clothing when handling chemicals. When applying the chemicals to the pool, you should do it as close to the water surface as possible to prevent them from splashing or being misdirected by the wind. Rinse off the container after the chemical application to prevent damage to yourself or the surrounding areas.

Caution with Chlorine and Acids

You want to ensure that chlorine is never mixed with acids as it can cause extremely poisonous chlorine gas. It’s therefore important to keep chemicals in the original containers and keep them separate from each other. And to prevent accidental mixture, do not store liquids above powdered chemicals.


Sanitizers are added to the pool water on a regular basis to prevent the growth of algae, bacteria, and viruses. Chlorine is the most popular type and is typically available in a powdered or granulated form or as solid tablets. When using chlorine powder, you would normally dissolve it in a bucket of water first. When pouring it into the pool, distribute it evenly by walking around the pool’s perimeter as you pour the solution into the water. It’s best to start and end at the deep end of the pool if you have one. If you’re using tablets, they can be added to a chlorine float, into the skimmer basket or by using an automatic chlorinator.

Total Alkalinity And pH

Total alkalinity and pH are the water chemistry levels that you’ll need to monitor regularly. Ensuring the alkalinity levels are correct is necessary before worrying about pH as the alkalinity has a direct effect on the pH levels. Once your alkalinity is stabilized you can concentrate on pH. To know what chemicals, need to be added you’ll need to do a water test that will indicate whether the alkalinity or pH needs to be raised or lowered. To boost total alkalinity, you would use an alkalinity increaser. Reducing stubbornly high alkalinity levels might require the addition of muriatic acid or draining the pool altogether. For pH adjustments, you would use pH increasers and decreasers.
