I’m a rookie to all this and we got this filter from my Lfs as a trade for a our freshwater filter. (We started with a freshwater tank but the well water was way to alkaline and ph was way too high so switched to saltwater.) After I put filter media in the well the protein skimmer started picking up tremendously. Really great, nasty water the first couple days. But now it’s just filling up with what looks like regular tank water, and it fills up in about 15 min. Is it working properly? Is it supposed to flow over that way? Please see the link for the video. Thank you!
