Just had a Jandy JXI 400 propane heater installed yesterday (didn't expect to be able to do a heater this season, but one was available and installer had an opening.....plumbed and electric hook-up yesterday), working on propane hook-up. Installer was discussing LSI with me and impact on the heat exchanger over time. I explained that I do a pretty good job maintaining proper levels with a TF-100 kit on a weekly basis, but have not paid attention to LSI calculations. Ours is a vinyl pool and maybe mistakenly I've not really focused on CH level because of the vinyl....but he said I'd definitely want to pay attention to that and bring that level up. Below are my current numbers and you can see CH is 25. I downloaded the Orenda calculator and with my numbers the LSI is pretty far out of wack. I've also read a few threads here discussing CSI calculation vs LSI....so which should I follow? Looks like the Pool Math app has CSI logging and the Orenda app is LSI.....thoughts on which to follow to "properly" balance my water.....goal being to extend the life of the heater equipment?
