Hey 77. thanks for chiming in. I realized after finding the bakpak manual online that it is the valve. I havnt messed with the skimmer yet, just the emporer HOB. I will check tonight. I emptied the cup when i moved in and there was stuff in it. I cant see behind the tank to know. I am probably going to take it off this weekend and clean up the salt creep and run vinegar thru it (not sure of it has "bio bale" but if so i will take that out and keep it wet).
It sounds like, given the current bio load, I may not even need the HOB filter?
