Hello all, my pH is low (bright orange = matching 6.8 box of Taylor test from my TF100 kit), my TA=90. So obviously I need to raise pH without raising TA too much. From what I read, it sounds like in such circumstances it is better to use Borax than washing soda, as the latter tends to raise TA more. However, since Borax is poisonous, how long it takes before anyone can enter the water after the treatment? And, when should I test pH again after adding Borax, to see whether I need to add more (obviously pH=6.8 is the lowest Taylor can get, so I am wondering/worried it might be actually even lower than 6.8)
Thanks in advance.
