Hi all! Haven't been here in a good while, mostly because things have gone pretty seamlessly with the spa operation.( In good part because of the great advice I got from everyone here back in October)
In any case, we purchased a Dimension I spa with the Vision and ozonator, filled it and the 4 of us (two kids, two adults, occasional friends ) probably using it 2-4 times per week (down from daily when we first got it)
It continues to be lovely and clear, smells great, and is staying easy to balance if it's a little off in the ph dept or what have you.
Now it's been 4 months...is there some parameter that will say "change the water now!"
Or is it Ok to leave it be if all looks and tests well?
The PPM is creeping up a bit, probably a bit over 100 if I trust the chart color--I think I remember that being a marker?
Thanks in advance for any advice!
