You can use either type of salt, but the salt for pools is better because it dissolves very quickly. 40 lbs bags cost around $6 at major home improvement chains. It is highly recommended to use nothing but pool salt for chlorine generated pools. YOU CAN NOT USE "EITHER" TYPE OF SALT!!! To save a few cents per bag of salt will cost you an arm and a leg in repairs to damaged equipment ( salt generator). Swimming Pools and related equipment do not do well when you cut corners on cost. You may be able to do it on a few items but in the long run it will end up costing you more. USE WHAT IS RECOMMENDED BY THE MANUFACTURER OF THE SALT SYSTEM !
No, it is sodium chloride in most cases.
In a typical saltwater swimming pool nothing living other then micro organisms should be able to survive. In a saltwater pool with water, filtration and components designed for marine life, they could.
A fresh water swimming pool is a swimming pool that does not use a saltwater chlorinator. A pool that used a salt water chlorinator has salt added to it to so that a salt water chlorinator can electronically convert part of the salt into chlorine. A fresh water pool has chlorine added to it directly either manually or Automatically.
No, salt does not damage the plaster. Improper water balance will.
Yes.
Yes it makes no difference to what the water looks like. this is influenced more by the colour of the pool and the sky then anything else.
Just backwash until it is at the level you would like it to be. Or get a floating swimming pool skimmer ond take advantage of the free water and save on pool salt if you have a saltwater chlorinator.
Not at all.
Sorry, but swimming in a saltwater pool is a lot different than swimming in the ocean. In the ocean, pollutants like oil, gasoline, and trash combine with fish urine and dead animals. Another big difference in a pool is that there are no waves! In the ocean, rip tides and tidal waves are a big part of the ocean's cycle. In your pool, waves are non-existent.
sodium chloride
Yes, you can add a clear saltwater system to a ProSeries 14' X 42" Metal Frame Swimming Pool.
Not sure on MS, but in CA saltwater is ok as long as there is a measurable free disinfectant available.
It just stays there. some is lost to the backwash , splashing, overflow and so on but the salt that is in the water stays there.
