Using salt in liquid chlorine pool

I've been reading all the info on TFP for the past few months and I recently discovered the pool school ebook. I never read the information about salt since I don't use a SWG but while reading the ebook I saw that it says "For improved water feel without a SWG, try levels around 2,000." I use liquid chlorine as my sanitizer and was hoping someone could explain to me why I would use salt without a SWG. I thought one of the things at TFP was only adding necessary chemicals, so there must be some kind of benefit I'm not understanding from having just salt alone. Would adding salt to my pool have any negative impact on the pump or the robotic cleaner that I leave in the pool

Welcome to TFP :)

All pools are salt water pools, the liquid chlorine you put in your pool every day is salt water.. I bet your pool is already above 500 ppm salt content... most pools stay right around 1500 ppm salt.. Get a Taylor K-1766 salt test kit and check to see how much you already have before adding more..


It will not hurt anything being in a salt water pool... My systems have been in salt water pool for 9 years now and nothing is wrong with the pump and filter.. It will make the pool water "feel" better when getting out and you will be closer to getting a salt water generator for the really easy pool care.. once you go SWG you will never go back, it is life changing.. If mine died today I would have another one ordered tonight :)

For reference, the ocean is 35ppt (parts per thousand) salt. "Saltwater" pools are between 2 and 4 ppt. Non saltwater pools are typically between 1-2 ppt. Adding a little salt does improve water feel. The main difference between a saltwater pool and non-saltwater pool is a saltwater pool has an electrical device that is able to split saltwater into its elemental parts, one of which is chlorine. It is still a "chlorine" pool, it just has the ability to make its own chlorine. Most people that convert do it for the ease of maintenance. But water feel is also a prime factor.

+1. Was in the ocean last night. It was like swimming in Campbell’s chicken noodle soup.

The salt pool is like being on a strict diet with just a very light sprinkle of salt to the meal.

A lot of pool builders talk about the corrosive effects of salt on coping, concrete, and killing plants. Some have people sign waivers if they do a Salt Water Pool. I think I would avoid one of those pool companies, since they obviously don't know what they are talking about. My pool builder pushed back against salt water pools.
