Inground concrete 9 x 3 x1.2 Hayward salt chlorinator T7 cell, have tried liquid H2SO4 now using PH-,PH ok for about 3-4 days then back to 8 plus on water test, chlorine at top but ok running cell on 15%. Salt registers 34000 which is normal range 28 -36 ok.This pool is totally enclosed from outside eements even insect proof. Run filter 1 hour morning and night also robot cleaner once a week. Use daily for an hour, wife and I plus kids at weekend for a couple of hours. Pool is overflow system and do not see a lot of waste water. Have brought PH down to bottom of scale and turned off outside water and at the end of week PH has climbed back to 8 plus. Water looks excellent and can see at night with lights on water shows nothing looks really good. Water great to swim in no sore eyes or itchy skin but am concerned about calcium build up in T cell or on tiles

Hello Wazza1 - The pH in salt pools will always run on the high side. It is normal to add pH minus or muriatic acid every few days. There are chemical feed systems available that will inject a small amount of muriatic acid periodically into the pool water. Something like the Stenner pump and tank system would accomplish this task.
