simply buy the required amount of salt for the pool from a pool shop or other salt supplier and and toss it in the water.
I don't know, because it is not true the amount of salt that is used in a salt water pool while slightly more corrosive then fresh water (About the same amount of salt as you find in tears) will not cause any appreciable damage to modern pool equipment as it is made for salt water pools, salt water pool being by far the most common pool these days.
salt water does provide a lower degree of freezing temperature but the normal amount in a salt water pool is so low that the answer is "not enough to make a difference". Protect your pool and equipment from freezing as you would if it weren't a salt water pool
Yes The amount of salt in a salt water pool is about 3,000 parts per million the average bowl of soup has far more salt in it.
No, the reason you have to have a certain amount of salt in a pool, is for disinfecting and cleaning reasons.I own a salt water pool and the salt level is not always correct, but I notice no difference. We also have pool guys and they handle the salt with no gloves.
If you have a salt-water pool and you have an indicator that says add salt it means that the amount of salt in the pool is not enough for the chlorinator to manufacture chlorine. Take a sample of water to your pool shop and they will help you with what is required. Or get a couple of bags of salt and add salt until the salt warning stops. The latter is a bit of a dodgy way of going about it.
Add salt
the same salt water system used in a pool is also fine for a spa. the amount of chlorine generated is determined by the input current to the salt cell and the amount of time in operation.
Yes as a mater of fact that is what salt water pool normally is. With a salt water pool there is a electronic salt water chlorinator installed that uses the salt in the water to create chlorine. However if you don't have a salt water chlorinator and prefer the feeling of a salt water pool then there is no reason not to add salt to the pool as well as keeping up the chlorine yourself.
Go to your pool shop and they will be able to supply you wit a floating gauge that will do the job for you
No the concentration of salt in a saltwater pool is about equal to the amount of salt found in tears so there is nothing to worry about. as a mater of fact it is probably good for it.
No. salt water is salt water. it already has salt in it
