Can you give GH leavles of your mix water (RO with any mineral topics added and the water it's mixing with) along with your target GH. What is you knowlage of water chemistory like? I ask, as playing with pH GH and more importantly KH leavels without a good understanding of the processes behind how it all works can lead to severe problems, such as pH crashes.
Looking forwared to your reply
