Evolution of the Bullet Skimmer

This article describes the thought processes, and the construction of the Precision Marine Bullet skimmer. I have been very fortunate to be involved in this project, from its conception to the final production models. Hobbyists need to see and understand what actually goes into building a skimmer, and that is my reason for presenting this report. The construction materials, testing, and final optimization of the unit, adds up to a serious commitment of time, effort, and money. I must thank the owner of Precision Marine, Mike S. for his commitment to the project, for without his expertise in constructing these skimmers, and providing the raw material, this project would never have gone forward.

Back in August of '98, another avid hobbyist, James Wiseman, and I had been discussing our fish tanks. In particular, we had focused on the role of feeding large amounts of food in a closed system. One concern that kept arising was how our tanks would handle this nutrient load. The outcome of the discussion was that if we wanted to feed heavily, we would have to find a way to export the extra waste. One possible solution to this problem is to eliminate the extra nutrients via skimming (foam fractionation). Both of us had used traditional air-powered or counter-current skimmers and were disappointed by their lackluster performance. We thought a more efficient... Read more...
