My 29 gal. aquarium

i just bought a aqua clear powerhead rated for 30 gal and i also bought a Berlin Air lift 60 skimmer, any good? and finally got a salinity measurer
 
Most people swear by either the Remora AquaC and the new coralife super skimmer. I just got the remora for christmas and it has been working really well on my 20 gallon. You dont have to screw around with it to make it skim what you want. I am not familiar with the berlin skimmer so maybe somebody else has something to say about it.
 
The Berlin is a good choice, from the reviews I've read. I'm thinking about getting it myself. Is the one you are talking about an in-tank skimmer?
