Welcome to TR!
I had a
Ca shock too a bit ago: 700
ppm. I did the test again it it dropped to 550
ppm. Still high but it shows how finicky the test kits can be. I use the Salifert one which requires a scoop of dry colored stuff. I have actually gotten into the habit of thinking of it like a scoop of flour. I dig in with the spoon they give and then scrape over the top with a knife to make a perfectly level scoop. I assume it works now; i would really like an electric meter though!
TR is a great site! We are glad to have you on!
