salt mix.
 

hey, i work in a dialysis unit and have access to ULTRA pure ro/di water. if was to mix lets say 20gal of water would it keep ok? or should i jsut store the ro/di water then mix when i need it?

Store the water until you need it.

Heat to tank temp and aerate with a powerhead large enough to really move the required amount of water for at least a day before adding salt mix.

It's been my experience to not let the salt mix stay in the mixing container longer than a day, otherwise it will often begin to precipitate stuff on the sides of the container.

thanks for the info :biggrin:
