FunkieReefJunkie, I am curious about the "top hat" structure
at the bottom of the skimmer...
#1) Can this piece be removed to clean the bottom of the
skimmer? It looks to be glued in place.
#2) The input from the pump appears to empty into the upper
portion of the "hat" (labeled "bubble injection chamber") where
the bubbles rise up through small holes into the skimmer body.
Is this chamber open to the lower "return chamber" near the
bottom? Or does this chamber have a solid bottom so that no
bubbles can travel downwards? I suspect the latter.
#3) The small holes at the top of the chamber appear to be
tapered. Is this correct?
#4) Is my cutaway sketch reasonably accurate in terms of how
the bubbles flow?
