First off, hello! Been a long time lurker and have recently made the dive into reef aquariums. Searched forums and could not locate an answer, so figured I would ask here.
is anyone familiar with the shut off valve posted below? Noticed it had a removable brass nut which blocks water from flowing out. Could I somehow attach RODI to this location or would I have to run a dedicated line? Thank you.
