hi i check my tds quit regular since got system a month ago was running at 0 ppm up until last fri, when checked on sunday was 1ppm so ordered resin for change but checked again today and it as shot upto 10ppm. my question is is when it starts to go does it go very fast as it has been at zero for ages then 1-10 in a matter of days.
also at what tds should i change i believed this to be 2ppm but cheked the windows after today and they where good as it was the second clean on the house.

I always change mine at 002.

Some products will shoot up very quickly whilst filling, I find Tulsion will remain at 001 for around 1500l then it will shoot up.
