PPM

[hammy]

Hi all,

just wondering when we talk about ppm (eg, 10~20ppm for KNO3, etc), are we refering to the entire tank's volumn or just the part after water change...because if its the latter, how would we know how much is left in the tank (after water change) to determine the desired ppm level?

Hi Hammy,

It's refering to the entire tank's volume.
