Calcium hardness rising

[duxthaman]

Ok so I've been testing with my new TF100 kit since Saturday. Starting to get the hang of it. Got a speed stir and that's fantastic.

Here are are my original tests from Saturday morning:

FC- 6
CC- 0
Ph- 7.9
TA- 150
CH- 350
CYA- 90

took the tricolor out at this point and started adding bleach and MA, while aerating to bring TA down and increase FC.

My my readings tonight are:


FC- 10
CC- 0
Ph- 7.7
TA- 110
CH- 400
CYA- 80-85

Why is my calcium hardness rising? I know it's still in the acceptable range but was curious why it's rising?

2 drops difference? Likely within the noise or minor testing error. I would not worry about it and see how things continue to trend.

Ok, thanks...still new to this so wasn't sure if it was something "known". I'll just abide and keep it cool man
