Hi All - I'm so excited to have found this forum. I got my first new hot tub in Feb 2023 and wish I had found this group sooner. After suffering a lot of unbalanced water chemistry my first 3 months, I found Ahhsome and everything got much easier with the first purge. Plus, trading up to the K-2006 drop kit from test strips was a game changer. I have a 370 gal tub with UV-C and an ozonator. I struggle the most with borderline CH (~100-110), high pH (8.0) with borderline low ALK (~70-80). It's been baby steps, but I'm getting there.
