Hello all. Setting up my 93 gallon cube tank and I am having some skimmer issues. I picked up a used deltec sc1455 skimmer which was working perfectly in another display tank. Set in in my sump on an egg crate platform in just under 9 inches of water which is in the parameters of the skimmer as per the manufacturer. Now keep in mind this is 50% new salt water and other half was from an established tank to help cycle faster. Currently have no live stock but wanted to try and get the skimmer tuned even if i wasn't collecting anything. I can not get a foam head to start and the water level is at the top of the regulation tube and still can't get foam high enough to reach the cup. Only thing I notice is that I am missing the regulater on the Venturi line from the pump. So it is just free flowing air. Is this the cause of my problems or is it since I have no real nitrates and new water that is causing me the issue. Any help would be appreciated. Also the Venturi line is not clogged because when I put my finger over it I notice a huge difference in water level in the skimmer.
