Depends on the type of sanitizer. Chlorine pools may use Calcium Hypochlorite, Sodium Dichloro-s-triazinetrione, lithium hypochlorite, sodium hypochlorite, Potassium Per-Oxy-Monopersulfate (Non-chlorine shock) and even gas chlorine. Non-chlorine pools may use Hydrogen peroxide, UV bulbs, Electrolosis through titanium plates and many other methods.
Absolutely do not mix shock with bleach. there are chemicals specifically designed to remove Iron from the water. Ask your pool supply store. Hatawa
Backwash first then shock. If you shock and then backwash you will be throwing away the shock you just put.
Have the water tested to ascertain the cause (organics, iron, etc.) If it is organic (algae, etc) you want to shock the pool with chlorine. If it is iron you want to use a chelating agent, available in your local pool store, to remove the iron from the water before you shock..
People use salt, bromine, chlorine, and other assorted chemicals
you should use a chlorine floater, shock it once a week and add algaecide weekly as a preventative.
The saline system will eliminate the need to add any sanitizing chemicals (pool-chlorine, algaecides, 'shock' chemicals). Everything else about the water treatment remains exactly the same as for any pool (pH, alkalinity, conditioner, vacuuming etc etc).
Pool filters are designed to remove impurities from the water, such as dirt, leaves, and other debris that can make the water cloudy or dirty. While pool filters can help improve the overall quality of the water, they do not remove all chemicals. Chemicals used in the pool, such as chlorine, are necessary to keep the water clean and safe for swimmers. Therefore, it is important to regularly test the chemical levels in the pool and make adjustments as needed to maintain safe and balanced water chemistry.
3800 gals of pool water shock it with 1 gal bleach
Yes; mix the shock with water and pour it into the pool directly in several locations and run the filter.
If your pet get into the chemicals see a vet. If your pet is drinking water from the pool, even after chemicals have been added to the water, they will be ok.
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.
No the concentration of these chemicals isn't strong enough to do any harm
