Dont know what it was. The skimmer was new. Tank was nothing special really, a 42BF FOWLR with 4 fish and LR. Salinity was 1.023. No additives, dechlorinators or anything were used. I even did a big (70%) water change to try and get it to work. No luck. I took it apart a couple of times. Nothing wrong, no clogs or anything. You could not run it as the directions stated with the air @ 2:00. The cup would overflow instantly no matter where it was. Wide open with the cup just in the body enough so it didn't fall out was the best it could do. It it was lower, it would run fine for hrs, then just overflow all over the place for no reason at all. Very frustrating especially since they bought it on my recommendation. It was embarrassing for me.
