New fill after flushing away the old... But I still have questions. After cleaning & flushing; this I know:
Add new water (60° starting temp)
Install clean filter
Add Metal Gon
Add Brom-start
Add Calcium hardener if it's low (from the well, it's 100, it should be 250)
Test for Alk, PH, Bromine. Adjust with Spa-up or Spa-down.
Enjoy when temp is 102°.
Now my questions:
Should the new water be added, then brought to temp (at least 80°) before any chemicals are added?
Should the new water be shocked before first use?
How long should I wait between the steps above?
Over the history of owning a tub, I've always had trouble getting a Bromine response above 1 (with exceptions, of course); it should be 3 to 4. I have the feeder set to 4 openings.
We have a full time recirc and O3 (Ozone) so it's never been too concerning, but I believe there something I should be doing to get a better number.
Tanks, and Soak On!
