I got the maintenance and warranty information for my Leisure fiberglass pool and here are their recommendations
Strictly between 7.2 and 7.4
Must be recorded monthly for warranty purposes
Ideal is between 80-120
Between 1 and 2, never exceed 5.
I know it's slightly different than the BBB recommendations especially on the PH so will need to increase my acid to drop it since it 7.6 right now. But will have to go by them due to warranty reasons.
