as soon as you put the water in you can ad chemicals to it
To raise the pH of your pool you add soda ash (sodium carbonate). To lower the pH of your pool add muriatic acid (hydrochloric acid) or sodium bisulfate. You should always add chemicals with the pump running and check your levels again once the newly added chemicals have been circulated around the pool.
no. there are "natural pools". but if you want the classic clean blue pool, you have to.
Most authorities advise adding chlorine (and other chemicals) in the evening. I would not add any chemicals during the hottest part of the day or when the sun is beating down. Most people prefer to add pool chemicals at night after they're through with the pool so the chemicals can work overnight.
You will need to add an amount of chemicals that is proportional to the size of your pool. The containers of the chemicals should tell you how much to add for the size of pool you have. It might be better if you take a sample of water to a local pool supply store, so that they can tell you exactly what you need for your specific pool. http://www.ehow.com/about_5390392_chemicals-put-new-pool.html
Add clarifying chemicals and turn the pump back on.
Add chemicals in manually and give it a good stir every so often.
Water needs to be tested for, lets say, a pool, because it is important to know what chemicals to add to your pool.
You can add chlorine and that should keep the pool very clean.
Make sure your chemicals are balanced and add a clarifier available at your pool supply dealer.
You can add some kind of herbs to the pool.
This is something that can be done yourself, or with the aid of a local pool supply store. You need to test your water to see what the level of chemicals are, and add chemicals to balance the levels.
Well, whether it is illegal or not to clean a pool with people in it is unimportant, it is inadvisable considering that most of the chemicals that are added to a pool are hazardous until dissolved in the proper concentrations in the pool. Most of the chemicals used to balance or clean a pool need at least several hours and sometimes up to a day to disperse completely in the pool water. Some of the chemicals are relatively mild like baking soda, but others can be quite deadly to humans such as the chlorine and the acids used to adjust ph. never add shock to a pool when there are people in it. other chemicals should not be added either, even though they may not pose a threat.
