Calcium Rise Without Dosing

[Ponterbuck]

Not sure what you are suggesting. Precipitation of calcium carbonate on sand lowers calcium and alk.

Dissolution of enough sand to boost calcium to 660 ppm from 400 ppm would ADD 36 dKH of alk to the water.

So the sand seems an unlikely explanation.

Test error or overdosing seem likely.

Randy like i said i was taking a shot at it! I was just guessing. Your explanation sounds dead on nuts to me!

Randy thanks for the info! Liked i said it was a guess. The reason mine is high is I switched to red box fritz salt from the blue. I didn’t write it in my log book. I don’t even remember doing that switch! One to many head injuries! I’m loving this place i get so much information now If i can manage to retain my thoughts!!! I DO try to learn about one topic a week so maybe someday….lol
