Have a wallyworld test kit so I cannot do some test.
Hardness test seems to not be working correctly.
5.0 CL (seems to be around 6-7 kit only checks to 5)
7.8 PH
130 TA
45 CYA

I think my problem was shocking the night before I added water in the early am. Need to try to add fill water when chlorine is on the low side.
And of course keep using metal free.

Thanks
