Thanks for posting, just drained and filled my spa. Added some bromine reserve, 1 TSPL dry acid, 1.5 chlorine free shock, some scale, and let it run for a hour and added 2 bromine tabs. Currently water is at 65 degrees...
I'll post my water analysis once it's at temperature.
I notice a difference in the water appearance already. After chasing PH and TA numbers after initial fill, maybe a month later, I noticed when the jets were on high, almost a seltzer effect of the water. Almost like when you pour a glass of soda into a glass, you get a lot of fizz. I guess it happened slow enough over a month that it wasn't noticeable but I just ran the pumps on high and that effect is now gone. I do know I was adding dry acid, then baking soda, that acid, then soda etc...
Would love some advice after I post my numbers... Seems this site is getting less traffic but if anyone can help I would so much appreciate it
