I can say that I have a salt water pool with a liner. I’m on year two and trying to learn the chemistry.
unfortunately it was opened at super chlorinate and I didn’t know to lower it. I also have a auto cover that I use all the time so it didn’t off gas enough. Early I saw an oily film on the water. Then a thick yellow build up that we now think was hydraulic that was getting pulled by the cover. By the end of the season I had a massive oil/ hydraulic film that was undeniable. I have no idea how I will get it cleaned now or how much. ? the scum bugs weren’t enough. Tons of rust built up on the unit too. Obviously PH is extremely important. I will look into an organic oil vs the hydraulic. I’m frustrated with the guy that opens and closes so I may search someone else. I hate to replace parts already but the filter is a mess and the rust is extreme.
