Hi, I am in the process of balancing my water. My original TA was 300 and so far by following the acid/airation method I have added 400g in total of acid and it is still only on 140. What would be the normal amount to have to add altogether to get the TA from 300-100. My tub holds a 1000ltrs.
I understand that ph need less acid to adjust it the lower the TA is but does the TA become easier to adjust as well or does the reduction in TA stay directly proportional to the amount of acid u add No matter what the TA is (eg 150g will adjust a TA of 300-260 and a TA of say 140-100.) If thats the case as TA comes down u add less acid to adjust ph from 7.8-7.0 and therefore the TA adjusts less?
