With a SWCG dropping your TA to around 70 ppm will slow the pH rise caused by the cell generating and causing aeration of the water which causes CO2 to outgas which causes pH rise.

However, before you attack TA get the CYA in line and get the unit adusted to maintaiin 5-6 ppm FC. Then adjust the TA and keep your pH between 7.6 to 8.0 (actually, when it climbs above 7.8 drop it back to 7.6.)
