This article "Aquarium-Pond UV Sterilizer History" has been updated. Here is an excerpt: "Internal/Submersible UV Sterilizers:
Circa 2007- ? Internal/Submersible UV Sterilizers/Clarifiers in their current form are relatively new to the aquarium/pond hobby/industry. However, they have unfortunately taken the hobby by storm. Why unfortunately? Because the vast majority are only good as clarifiers, despite less than honest statement these can actually be useful for disease pathogen control and Redox balance magnetism. The other major issue is many have issues with seals and/or ballast, resulting in life spans of well under a year, which does not seem to show up in poor Amazon reviews since these UVs usually get reviewed based on initial use.
It is noteworthy that one of the first to enter the market was the Green Killing Machine. It was quickly rejected by professional aquarium maintenance professionals due to its short life and ability to only clarify, but good marketing to discounters has allowed this product to unfortunately proliferate the market."Carl
