Constant flow rates are achieved, thus no adjustments are required. The small submersible pump running the skimmer is energy efficient and produces less heat transfer than do larger, external pumps. The Turboflotor fits in any sump, under the aquarium. The Bak Pak bio-filter is an external, hang on the back, combination protein skimmer and biological filtration unit. The Bak Pak is designed for a tank to 60 gallons, but you may use multiple units for larger aquariums.
Water first enters the protein skimmer column from the aquarium.
It then flows through the biological chamber filled with Bio Bale filtration media before returning to the aquarium. The protein skimmer is driven by a Rio 600 with the rejuvination system modification which mixes air and water before it is drawn through the impeller and broken up into tiny bubbles. Bubble dwell time is increased by the counter-current flow in the skimmer column. The quality of the foam collected can be controlled by lowering the collection cup. The benefit in this is that organic material such as proteins, lipids, enzymes and amino acids are hydrophobic, meaning that they have a tendency to rise to the surface.
