I recently purchased a new bak pak 2. I'm a little confused because the setup says to lower the collection cup until it is 1/8" below the water surface. However, when I do this the bubble level never makes it to the top of the cup. It sits at the very bottom no matter how I adjust the air inlet. Now when I push the collection cup all the way down the bubble level is higher, but still not at the top of the collection cup. I have looked at some videos online and other skimmers are constantly producing large, frothy bubbles at the top of the cup. Could it be that my problem is the skimmer is still in the "break in" stage? It has only been running for 24 hours. Any ideas? Thanks in advance.
