Hi all, need some help please. I just got an external RO 110ext protein skimmer that I'm trying to install outside the sump of my 60 gallon tank (30 gal sump, total 90 gal). I'm pairing it with a DC pump (Jebao DCS-1200) rated at 320gph. No matter what I do, water over floods the skimmer, flooding everything. I open the gate valve all the way, floods, close it, floods. I've turned the DC pump down all the way and still floods out the top. I used to run an HOB on my old set up, which was plug and play, this is new venture. Am I missing anything? I feel like I've reached the end of the internet and can't find an answer. Thanks in advance.
