A lot of the time I find people who do a fresh fill from a well and shock without using a scale and metal out. End up having discolored water. It is always a good idea when filling from a well to use a metal out. After letting the water circulate 24 hrs. continuously you should check and adjust your Alkalinity and PH if necessary. After Alklalinuty and PH are adjusted to their proper ranges ALK-80-120ppm PH-7.2-7.6. You should make sure all metals are out of your swimming pool water. Your local pool dealer can help you with testing these levels. After all metals are ride from the water you may then shock your pool. Ideal chlorine readings are between 1-3pm you should try to maintain this level to ensure crystal clear water. Note: during the day time hours it is rare to have a chlorine reading in your pool. The sun burns chlorine levels out of the pool rather quickly. It is always advised to add your chlorine after the sun goes down. To ensure your pool water is sanitized properly. If after doing all of these steps and your pool water still seems to have a brownish/black tint to it. You may have a black algae forming. They make algicide for black algae always follow the directions to a T. Algae usually causes a slippery feeling to the liner. If the liner seems to be colored in spots you can try a chemical called stain treat by United chemical. It works wonderful with spotting on the bottom of liners.
you may have metals in your water especially if its well water. Use metal free before you add chlorine.
This usually occurs if your water has a high mineral content; the chlorine reacts with the minerals (ie well water) and changes color. You can treat with a chelating agent or metal remover.
Sounds like a problem with too much iron in the water see your pool shop about this and they should be able to help you. Take a sample of water with you when you go.
Stop adding salt to the pool and use tablets and shock when needed.
24 hrs
yes
Shock your pool at sundown and you can swim in it the next morning.
It is chlorine reacting with the metals in your pool water.
A person can go swimming in a pool a few minutes after adding algae treatment and shock to the water. This is provided that a low dose was used. The manufacturers of the algae treatment recommend that a person waits 45 minutes to an hour to swim after adding a normal dose.
Salt generators make the same chemical, sodium hypochlorite, that you buy at the store. The major difference is that it costs a lot more to make than to buy it. See other posts I have made in this arena for more info.A salt water pool IS a chlorine pool. Period! IF it needs shocking you shock it the same way as any chlorine pool, by adding more chlorine either by manually adding it or setting the SWCG to the boost or shock setting.
Backwash first then shock. If you shock and then backwash you will be throwing away the shock you just put.
A green pool is often easily fixed by adding "shock" to the water, or cleaning. Any local pool service listed in the local paper or yellow pages should be able to address the situation readily.
3800 gals of pool water shock it with 1 gal bleach
There is chlorine shock and non chlorine shock. Fo chlorine shock, which is the normal shock, it is the same a s Chlorine but unstabilized, so it will not last in the pool very long.
You do not need to remove it.
