Bottom of the bubble plate after being removed. As JCTewks and hahnmeister obseved, this split-plate design allows the bubble plate to be easily removed through the neck of the skimmer.
Here is the area below the bubble plate. Note the clear acrylic deflector. I'm sure this helps eliminate the chance for microbubbles in the sump.
Here is one of the pumps with the pump cover removed. The mesh mod could have been a little better. This is the only complaint so far.
