You require to have a variety of swimming pool chemicals in order to maintain healthy and clean water. The different chemicals do have an important role and these general types are mentioned here but before you spend any money just be sure you know where you are going to keep them.
The first one you should look at is known as a sanitizer and this is the one that deals with any bacteria that may be floating in your water. The main chemical used in this type is chlorine and it is this which really cleans up the bacteria but care has to be taken so you know that you have added the right amounts for the amount of water and be careful you do not overdo it.
You have to look at using some kind of ph correction because if the ph is too high then things such as the chlorine are not going to be able to work as well as it should. This particular chemical helps to keep the water around neutral and it does mean that the water is going to be a lot healthier and free of bacteria as a direct result.
Flocculants are really designed to help your sand filter and it normally includes aluminium sulphate. What it does is it helps to prevent sand from going through the filter by releasing a coagulant and this in turn stops the water from becoming all cloudy which is what would normally happen.
The final chemical is intended to keep what is known as balanced water which really means the heater is not going to corrode. The chemical you have to add does depend on your own water as hard water or soft water can require different things such as the alkalinity being increased or even calcium having to be added.
These swimming pool chemicals have just been mentioned in brief but within each type there are different chemicals you can actually use. It is therefore very important that you do ask someone who is an expert at this kind of thing before you spend any money as at least then you know you have the right thing for your situation.
