150G is pretty decent size tank for reef. How about putting more emphasis on the actual equipments such as
calcium reactor, chiiler,
ozone reactors, etc then look into devices which will suit/control your needs the best. Pardon me if already done so. Google for more info. there are other forums which focus on reef such as Manhattan Reefs or Reef Central. Ask and I am sure some one will respond from their perspective/opinions/experiences, not just a theory. Who knows, it may even be me. LOL
Just an opinion.
BTW, there is a decent article about reef set up in the August issue of FAMA.
Check it out!
