So i bought a cheap amzon TDS tester since I was wondering what my water quality is like.
Out of the box i am not sure if i even need to calibrate for accurate readings but i looked at the manufacture detail and i could not find anywhere anything that says it needs calibration before use, or even how if i do need to calibrate.
My tap water reading is 161 TDS
My RO water is 190 TDS which is higher then tap does not make any sense
I also tests a bottle of filtered water and it was 21 TDS
.
My RO/DI filters are used and not new got them when I boght my tank second hand a few months ago.
I am new to this so any directions is welcome.
