BTW - I have owned about 9-10 RO skimmers. Some of them really are good - I have one with a Sicce PSK pump that is as good as anything that I have ever owned. I have had others with the AquaTrance, RO and bubble blaster pumps that were just OK - not bad, but not great. I think that most people who love RO skimmers have never used much else, or had bad skimmers. IMO, they do not outperform ASM, LifeReef or the Tunze suggested above, but you can certainly do a lot worse with a lot of the other newer brands.
Tunze and LifeReef are awesome skimmers if they are in your budget.
