My TA is 140. Do I need to do anything about it? I have read a couple different recommended levels & am not sure what to go by, my TF-100 directions say between 100-120 and TFP says 70-90+. I am now over both recommendations, most of the year it hung out around 120. I do not have a problem with my PH going up. I actually add Borax about once a week because it tends to go down. I also aerate sometimes instead to bring up the PH since the borax raises the TA some and mine has been on the high end. Thanks in advance for all your help.
