one pound of cal hypo, granule chlorine, will treat 10,000 gallons of pool water. So use 1/4 pound to shock, two or three times that if pool goes green. If pool has a vinyl liner use sodium hypochloride, liquid shock, instead of granules.
Stop adding salt to the pool and use tablets and shock when needed.
better to get a bag of shock rather then guess and do it yourself local pool supply should have it
our pool dealer sells us regular pool shock [champion brand] for our bromine treated 25,000 gal pool, have had no problems in last 5yrs
Yes, some pool shocks are sold with algecide.
The easiest way is to use 4 lb of non-chlorine shock. Hatawa
Cheese.
Backwash first then shock. If you shock and then backwash you will be throwing away the shock you just put.
bleach
Use a chlorine reducing agent. You can get them at the pool supply. One is called After Shock, but there are others.
The length of time between pool shocks varies. It depends on factors such as how often the pool is used, how many people use the pool and other factors. It is best to have a test kit to check the chlorine level and the pH balance to decide how often to add chlorine or to shock the pool.
3800 gals of pool water shock it with 1 gal bleach
