Title: calcium level
Post by: anne on October 28, 2006, 01:46:22 am

This is really weird: I just dumped and refilled (and the tub came up to temp in less that 6 hrs! Happy, happy!) We have really hard water around here, generally. I would have assumed that the calcium content of the water to my house would not change much. It has been 500-550 in the past. Granted, I have only checked it 3-4 times, as I did not expect it to be very variable. Tonight, after filling the tub and letting it get to temp, my Ca level is about 80!!!! What's up with that???? Now, I did add metal gone, but I'm pertty sure I have measured post-dosing before and it has still been high. I guess I should check the tap water. Duh.

I wish mine was that low.  :(   That's strange for it to just drop like that. :o  Maybe I'll get lucky too. :)

Yep, even tap water is 80. I measured it 2 times. Is this sort of tap water variation normal? Should I add extra Ca to my tub, or wait a bit?

Does anyone else have Ca that fluctuates from 550 to 80???

    It all depends on where your water supply comes from i.e. ground water, well water or surface water.  If your municipality is using ground water or you use well water, a large amount of rain in the last few weeks could have a dramatic effect on the hardness level
