PH was 7.4 for the last week and I've been trying half heartedly to raise it without raising my TA so I aerated for a day and got it up .2 ish. Today I aerated again for maybe four hours but also threw in a box of Mule about 2-3 hours ago as per the pool calculator. I just checked it and it's showing a PH of 8. I've stopped aerating. Is there a natural spike when aerating? The acid demand test was 1 drop to bring it down to 7.8 . I can of course use some dry acid but don't want to chase it back and forth. We've had a lot of rain lately and t-storms are in the forecast and Toronto gets acid rain. Any advice / comments?
TA Was 140 Now 130
