Thanks for the link, Dave. I think my magnesium had gotten way out of balance before the move. it was taking entirely too much two part to keep things balanced. I have tried to get Mg test kits four times and all four times they were either sold out or on back order (depending on where I tried). Good info. I was trying to get my alk/dKH a little higher, hoping it would help choke it out some, too. It got better at around 10, but never went away.
