My TDS will be slightly off because I had to change 5 litres (half a bucket of water) to do some cleaning.
after WC before dosing - 120-125 (can't remember exactly)
after dosing: didn't record
day 2
after dosing: 130
day 3 (changed 5 litres of water before measruement)
before dosing 125
after dosing 130
My meter showing a 5pm change looks reasonably accurate give or take a few ppm because my dosing is roughly 3.5ppm based on my calculations.
But I am surprised that TDS didn't change that much from the day before. Anyway, I have the whole week to check.
