I agree with the concept that a good skimmer is important. In fact, to me skimming has nothing to do with other forms of filtration. You can have an incredible filter, but without a skimmer you are not directly removing organic waste. You are simply breaking it down, generally into nitrate, and causing a reduction in the carbonates that make up your buffer system and help to stabilize alkalinity, calcium, and pH.
Bottom line, in a marine aquarium we want to leave the organic breakdown to live rock and live sand, exclusively. The skimmer supplements this process, and the better the skimmer, the more efficiently these organics are directly removed from the system. There are many factors that contribute to the amount of organics produced, and all of these factors need to be considered. Stocking level and type of livestock are very important considerations.
In many cases, less expensive models of skimmers will be very effective, such as The SeaClone, Coralife SuperSkimmer, and AquaRemora, each progressively better than the prior. When the need necessitates, higher quality skimmers are the way to go. The deltec brand certainly falls into the category of a high quality skimmer, and the results justify the price.
