Is it possible to dose Base Elementz without diluting in RODI?

I guess its unavoidable for the one dry element, but can the others be dosed straight out of the bottle? Right now i'm dosing 280ml per day so 28ml is easily possible with great accuracy from my Kore 5th.

They probably can, but I'll bet there is a much higher risk of stopping up the dosing tubing/pumps at such a high concentration.
Of course, you'll have to make sure that you are dosing the correct diluted amount of the alk (Elementz 1) relative to the other 3.
This will also change the calculations for how much tank water to remove in order to prevent salinity from rising.
