There are things (magnesium for one) that interfere with that test but only cosmetically.
So, it looks to me like that calcium came from your acid wash....Done is done but I wouldn't do that again. With your fill water around 125 CH and some rainwater, you can slowly reduce CH pretty easily.
If I remember, your water is clear and your TA still high. Is the TA what you want to deal with next?
Remind me what your water looks like
