With summer just around the corner, its time to get those swimming pools sparkling clean. So where is the best place to start when it comes to pool chemicals and how best to use them? There are so many options when it comes to pool chemicals that sometimes it feels a little overwhelming. Everyone wants that perfectly blue pool, but how do we get there?

Why Do We Use Pool Chemicals

Pool chemicals are the easiest way to keep you pool blue, clean and algae and bacteria-free. Pools by nature are open to all sorts of bacteria – from dirt and debris blown in by the wind to oils and skin cells from every time people swim. 

So, finding the best mix of pool chemicals before summer and swimming season starts is key to maintaining a healthy swimming environment. 

What Is The Best Option

There are many different options when it comes to pool chemicals, and you can use them all or just one or two – you can even opt for the natural eco-friendly way, but these are three of the top options when it comes to pool chemicals:

The Sanitizer

There are a few options when it comes to a sanitizer, but chlorine is the most popular option. Whether you use tablets or granules, Chlorine is what keeps your pool algae and bacteria-free.

The PH Balance

The PH of your pool is especially important as if it is incorrect then the chlorine cannot do its job. The two pool chemicals you need for this is a PH decreaser and a PH increaser. You will use the increaser more, but it is always good to have the decreaser on hand just in case.

The Shock Treatment

It is important to do a shock treatment to your pool on a regular basis. Otherwise known as super chlorinating simply means adding a high dose of chlorine to your pool in one go. This is a great way to get rid of algae and any stubborn bacteria.
