Welcome to our forum.
...When I refilled, my pH was 7.4, TA was 100 or so, without adding anything!...
I have only had the kit one year, so i hope that the reagents are not old.
Have you tested the pH and TA since the initial fill? My tub shows levels like that out of the tap, but its true high pH/TA shows up a day or two later. If so, the precipitation could just be an indication of unbalanced water.
I was told that the reagents are only good for one year.
...I just added a bit of baking soda to bring up the TA, but I seriously doubt that slightly low TA is causing ppt...Can anyone vertify for me that you get non ppt'ed CA measurements using a Taylor kit and N2?
...i think my water is high in other minerals... It was because I have always added "metal Gone" first....
Page 5 of the Taylor kit manual has a list of criteria for when the reagents are "old" but there are no listed expiration dates. I have stored them properly, and I have none of the signs of age (discoloration, floaties, etc)I doubt that they only last one year, or we'd all have to be buying a whole new kit every year. Puzzled......
