I'm gradually switching my tank over to RO, 10g per pwc. But usually when I do a pwc using tap water I use prime..i think im right in I don't need a container for RO because there are no harmful metal etc..correct?
That's right. RO doesn't need prime added to it. But, if it's for freshwater you may need to add minerals back to the RO water by either mixing it with some tap water or using a product like Seachem equilibrium. Pure RO water is essentially a solvent.
