I want to buy the PM Bullet1 or Aqua C EV 120...........which one is
better? My understanding they both work on same idea.
Also I never had a skimmer so help me undersatnd the sump, and how does
the water get to the skimmer, how does the water get back into my tank?
I have a 92 bow and want to set everything under the stand.

Please give me a list of what I need to buy to completly set up one of
these skimmers.

Thanks
