From the webpage:
"Protein skimmers help remove nitrate buildup, remove decaying matter and toxins, and replenish oxygen. By removing waste material, protein skimmers also help prevent aggressive algae growth and improve water quality to enhance light penetration for a brighter, cleaner, and clearer aquarium. Benefits are remove waste, decrease algae growth, lower phosphate, and improve water quality which can all be achieved by increasing oxygen bio-availability. The Aqua Ionizer directly increases Dissolved Oxygen content which allows greater oxidation of impurities and wastes. This results in the best protein skimming available on the market."
Sounds like the author has a grip on what a protein skimmer is (mechanical removal) and links a secondary claim (oxidation) to justify that this is ALSO a protein skimmer. Your call.
A long time ago the science was published as an advertisement. I take solace in the fact I use PVC (transparent to IR) and the magnets in my pumps are many times stronger as a magnetic field.
