Hi guys,

When using high precision scales to calibrate the 2.1 doser, what weight equals what volume of water?

For saltwater at 1.025, I think 100g = 97.5ml?
Freshwater must be 100g = 100ml?
And the reagent - what does 100ml weigh?

Bonus question - when re-calibrating the reagent pump, do you need to de-prime the head before disconnecting the tube?

Thanks,

Alex.
