[Killietalk] TDS vs. Conductivity

[Charles & Sue Harrison <csharrison at inkmaker_net>]

Simplicity is fine as long as one understands the primary 
fundamentals. The complicated parts belong in the theory. The bottom 
line:

  TDS is measured with a balance or scale.

Conductivity is measured with electricity/ a resistance meter.

if one keeps these thoughts in mind, then go run with it . . . raise 
n breed the fish with the knowledge and experience of those who come 
before and in your experience, tables and charts. measure what you 
can and change what is best. it is not all predictable nor 
controllable, but that is why we study Science, to control and 
predict our environment . . .

Change as much water as often as you can,
Charles H
