is a stefani water purifier suitable to create RO/DI water? does it do the same job? because i have one of them. apparently the purifier removes everything but fluoride so i dunno if it can do wat an actual R/O unit does.
any suggestions?
RO/DI is pure water. Basically there is nothing in it which is why it is the best for SW use. The salt mix you use to made your SW adds back the stuff that your tank, corals, and fish need.
