The bubbles in the rubbermaid are not unusual considering its your return from the tank. The baffles in the skimmer area look like they are being overflowed negating their use. Raising the skimmer tub level with the rubbermaid will drop some of the bubble creation.
Correct me if i'm wrong, but is the skimmer tub low to accumulate the overflow excess in a power down? If so then you need to raise those baffles. IMHO
