First posting. We gave up on our local pools stores this year and I bought a test kit and took over the maintenance myself. By reading through this site and following the recommendation, I felt like I had things under control. So much so, that I decided to switch the pool over to salt water. I installed a Circupool RJ60+ system earlier this week and followed the recommendation for chemistry. I am taking readings every three or four hours and am dialing in the %duty cycle on the SWG. My wife was not too excited about the switch, but I got her in the pool to prove to her it is not really that salty, and she immediately noticed the yellow staining in the steps. It was not there before, as my wife would have noticed. The skimmer basket is stained as well as the drain cover. All the exposed PVC (water return jets) are not stained.
After reading through the forums, I am wondering if it is iron? I am on city water and have never had this kind of problem before. If it is iron, the only way it could have gotten in the water was from the salt as the only other thing I have added is muriatic acid. I am trying to get my TA down from 90ppm and used muriatic acid to pull the ph down to 7.2 and aerate. Could the low ph cause this? Has anyone noticed this happening when converting to salt water.
