MY ph was running high so i took a sample to the store to see what they got. Ph was 8 and TA high over 300(which is what i got with tf-100). I added dry acid in two pound increments to correct TA. 10 lbs in total. TA still high but ph now 7.5, water looks great. walls are now feeling a little rough, I'm assuming because of the high ph? Just had partial water exchange about 2 months ago. any ideas on getting TA down? more dry acid? will the walls reverse back to normal over time? thx
