I think my skimmer has finally broken in. I went to check my tank after a brief power outage and found my sump full of frothy bubbles that had overflowed out of the collection cup. The strange thing is that I had to make major adjustments to get the bubbles to slow down to a reasonable level (turn the pump and lower the output tube almost all the way). I thought that it was already broken in (I've had it almost a month now) but I might be mistaken. My tank has been much cleaner than usual. First off, has anyone else experienced that having the pump at one angle gives drastically different results than having it at another angle? Its hard to explain, but the water intake is up against the skimmer body when the pump is at one angle. This results in a lower water level than if the intake is unrestricted. When the intake is restricted the skimmer is also much noisier. Since this has happened, having the intake restricted seems to be my only option for keeping the bubbles under control. Also, with this configuration the outflow is much less (when previously it had been so much that it was minor problem with splashing). I have an octopus 150 needle wheel which is similar to the euroreef and asm's from my understanding. It seems to be doing a good job now, I'm just curious if anyone else has ever experienced this. Am I doing something wrong? I apologize for the length and incoherance of this post.
