CYA...30 - 40
Temp...82 (water has not been this cool since May 1st)
Not concerned w/the pH & alk....... added MA to knock it down. New-ish plaster
My questions is: Why did my Cal go from a steady 250 to 300? Have added nothing except the normal bleach and the MA. I did the Cal test twice. I am not complaining about the cal of 300, in fact, I'd prefer it to be there; however, I was laying low to see if it would creep up on its own because of the new plaster??? Could this be the cause?
