I have an OctopusBH2000 hob skimmer. Its been running for months. I just added a hob power filter to my tank and didnt disturb the skimmer but it overflowed water out of the top. I let it settle down and plugged it back in and the water rapidly went to the top. I put the small valve that come with it back on the air hose and can manage to stop the overflow with adjustments but the air isnt coming out of the pump in a spiral like it always has, it seems to be going everywhere and I have an enormouse amount of air in my tank. I took it apart and cleaned it and its still the same. Any advice? Will that much air harm my fish?
