So today my DOS added 200ml instead of the scheduled 12.6ml and spiked my pH. I think it was related to the fact that I manually dosed alkalinity to raise it and I spiked the pH above 8.4. When I set up the dos I incorrectly entered an advanced code of "if ph > 8.4 then 0" the 0 was supposed to be "off". Would this cause the dos to add the 200ml instead of 12.6? I changed the 0 to off statement.
