On 7/18 we took the TA down to 50 with MA before we added the 50ppm borates with boric acid. 7/26 test had TA at 50, 8/2 test had TA at 50. All that time, pH was 7.4. We haven't been in it as much recently due to other issues going on but the pH seems stable.
Today when my husband tested, the pH was still 7.4 but the TA is up to 80.
Should I put in acid to get it back down to 50? I guess I thought that it would stay at 50 longer since we're using bleach for the FC.
I do need to use dichlor now to get the CYA back up since it's been since 7/18 that I've used it and based on another thread trying to figure out why my FC use is so high, I want to get it back up to 35 - 40.
I'm thinking since I'm going to use some dichlor to add about 8ppm CYA (it's below 30, I just can't tell how much below but it shouldn't be too much lower), the dichlor being net acidic should help drive TA Down and I don't need to use MA?
