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!
