Only one minor comment I have. Even though you have a vinyl pool and the higher TA with lower CH is OK for water balance, your SWG will cause a lot of pH rise if you have a higher TA so I would stick with a TA of no more than 100 and probably 80 is best (if you have a CYA of 60-80). You really only need a higher TA when you use an acidic source of chlorine (like Trichlor) and you won't be using that.
