No, salt does not damage the plaster. Improper water balance will.
My experience is that the stains will go away by themselves, through the effects of the chlorination of the water. Does not matter if the pool is a salt pool or fresh water pool. If the pool has a plaster finish, brushing the stains with a wire pool brush will speed up the process.
Filling a plaster pool with water from a salt type softener will severely damage the plaster. Salt water softeners exchange salt for calcium and leave the water in a calcium deficiency. Seeking its dynamic balance the water will leech calcium from the plaster to satisfy its need for calcium making the plaster etched and rough. Adding salt to regular tap water is not the same as filling with soft water as the calcium is still present in the tap water. 180 ppm of calcium is considered the minimum and low calcium can be raised by adding calcium chloride.
Very important that the water chemistry be correct, otherwise the finish WILL be damaged. Clorine, pH, alkalinity, calcium MUST be correct for a finish to last. A salt system IS a chlorine generating system and is not really relevant here.. A "soft" water system is usually not the right pH for a pool thereby causing damage.
you can put it in any time you like. before . during or after. ^^^ completely wrong. You must add salt after the specified time that the plaster manufacturer says.
What has been your chemistry balance for the year - month-to-month? Without seeing the pool finish, it seems that your pH and alkalinity have been off for months. What chemicals do you add regularly or on a weekly basis? I have much doubt that it was the conversion to salt. A bad plaster job would have other signs. Please, get back to me thru my message board. So that I can further analyze situation.
YES! Salt water DEFINITELY causes corrosion in your swimming pool. I am a 25 year pool professional and I have seen first hand what salt does to gunite pools. It will eat you pool equipment, stone, concrete, metal, you name it. Keeping your pH neutral will slow down the process of corrosion, but it is still happening, regardless of your water chemistry. Do yourself a favor, DO NOT use salt in your pool.
Salt acts as a catalyst in the chemical reaction that causes plaster to set. The presence of salt speeds up the hydration process of the plaster, triggering quicker crystallization and hardening.
It really depends on the initial balance of the fill water and the surface of the pool and the type of sanitizer system being used. Depending on the fill water you might have to initially adjust pH, Total Alkalinity and (for plaster and fiberglass pools) add calcium if it is low--calcium is a non issue for vinyl pools). If there are metals in the water (from well water or local conditions) then a metal sequestrant will be needed initially and as a regular maintenance chemical. Also, many new plaster startups require the use of a metal sequestrant for the first year to maintain the warranty and some startup procedures for plaster might require larger amounts of some pool chemicals for the first weeks to months (such as acid startup for exposed aggregate pools and bicarbonate startup for plaster pools.) If chlorine or a salt water system is being used then CYA (stabilizer ) will be needed, as will a chlorine source. (Salt pools need to have their chlorine level brought up to the proper level before the salt system is turned on by the addition of a chlorine source such as liquid chlorine or bleach.) If it is a salt pool then salt will be needed once the plaster has started curing (Salt can be added immediately in fiberglass and vinyl pools). If the pool is a bromine pool or a biguanide/peroxide pool then the appropriate sanitizers/oxidizers will be needed. Your first step would be to test the fill water and adjust pH, TA, and CH if needed, add any other needed chemicals (such as metal sequestrants) then add the appropriate amount of CYA if it is a chlorine pool (and the appropriate amount of salt if it is a salt pool and the plaster has cured for a month or immediately for vinyl and fiberglass) , and then add the appropriate sanitizer/oxidizer (chlorine, bromine, or biguanide/peroxide). If the builder has specific instructions for pool startup and plaster curing then be sure to follow them! The chemical requirements for a plaster pool are going to be different for the first year as the plaster cures. Typically, the amount of acid needed is much higher as the plaster is curing.
I have a salt water system and recently had my pool resurfaced. There was no staining. If you put your salt in the skimmer like you we're supposed to there should be no staining, If you put your salt directly into your pool it could stain from the minerals in the salt. If you used table salt there will be much less staining than if you used road salt. ANSWER:: You should NEVER use road salt or table salt. Wrong chemical make up! Follow directions on the "pool salt" bag. The salt goes into the pool and not the skimmer!! You must brush any salt that lingers on the floor until it is mostly dissolved. DO NOT add salt until the water has filtered for at least 24 to 36 hrs. or that recommended by the manufacturer or pool builder. Do not rely on other people to tell you what needs to be done. GO to the source -- builder - manufacturer. You should not have staining if the above basics are followed. Additionally, you must run the standard pool equipment for about 2 weeks or more. This gives the plaster time to cure properly. The salt system can and most likely be installed by the builder as he installs the pump and filter. The salt system unit will not be turned on until the plaster has cured. After the cure you must follow procedures on the proper start-up of the salt system. K
It should not be a problem at all. A: you should not have a water softener tied into the swimming pool PERIOD. The product resulting from a water softener can be detrimental ( not good) to the pool plaster and the equipment. In fact, it may harm the salt system readings and components.
Yes, salt can evaporate with pool water. As pool water evaporates, the salt content remains in the pool. When the water evaporates, the salt will be left behind and may accumulate in the pool. Regular testing and monitoring of the pool water chemistry is important to maintain the proper salt levels.
