So the mark 0.4 is really .40 ???
I'm sorry i still don't understand.???/
i thought with the black maker ending at 0.4 at low res.. times that by 2 = 0.8
so u saying 0.4 = and adding a zero at the end giving me 0.40
and that equaling 300 times 2 equals 600
Ron
1.0 is 1.00 and the last reading of 0.1 is 0.10
I just have to add a zero at end right ??/
But what about when it says times 2 , i times the calculated results .
like u said 300 times 2 = 600
darn why so high ? i'm not adding anything to it. (tank) i did another water change yesrtday. 3 gal
