I got my TA to 150ish and lowered my ph to 7.0 but I am having a hard time getting the TA lowered to 100 so I can add the Borax. I have the jets spraying to break the water and the kids played in it all day but the TA stays steady at 150 or 160. Can I still add the Borax and MA or should I wait and keep working at the TA to get it down to 100. I am afraid to let the PH get to low with the kids swimming.
