Probably. As it drinks water, ppm will go up. As it uses nutes, ppm goes down.@3rd
well I topped it off just now and it went from 310-300.....
So am I getting false readings because of the difference of liquid volume?
You need a line to put the water level at the same place everyday. When you top off, then check ppm, you'll see it drop daily.
