I have been struggling to get the pH up to 7.4 as it is, so I will need to be careful with the dichlor then. I still have trichlor tabs left over from last year that I can put in the chlorinator, is that a no no with my pool readings or could that work since I already have it?

FC:1.5
CC: .5
pH: 7.4
TA: 300+
CYA: less than 30

Water is crystal clear
