Re: Reconstituting RO/DI Water



Yvan......it is a commercial product.  It's a white powder that you put into
R/O water to reconstitute the stuff....only in America Yvan......buy a unit
to take everything out and then buy a jar of powder to put stuff back
in.........I was just kidding......some people use R/O right to add buffers
and some "things" back in the R/O water.  Some fish can't take a pure dose
of R/O water people think........certainly not right from hard to pure R/O
for sure but honestly most experienced apisto people just cut the R/O with
tap water........depending on your tap water!
