The Tropical Aquarium Purifier is an ozone generator from Philips, like the Philips that makes lamps, TVs, cameras and a whole host of consumer electronics. While walking the floor of InterZoo we actually strolled by the Philips booth several times but on the last occasion we very faintly heard one the booth hunks say something about ozone and our interest was immediately piqued. Philips and O3? Nah that can’t be right. So we strolled these bloggin eyes into the Philips booth to be surprised by an ozone generator called the Tropical Aquarium Purifier, an electronic product that was specifically targeted for the aquarium trade. Presumably Philips wouldn’t get into the aquarium ozone generator biz unless they believed that their product would be either very reliable, lucrative or both. At first we believed this would be the greatest aquarium product since flake food but then we saw that the Philips Tropical Aquarium Purifier mdoels produce between 0.55 to 1 mg O3 per hour. What in the world are you supposed to do with half a milligram, 0.0005 grams of Ozone per hour? Scrub a betta bowl? Makes us wonder why Philips thought a half a milligram of ozone per hour would have any use in an aquarium when the smallest ozone generator produce between ten and 100 times that. In any case, perhaps this would be a good ozone source for pico reefs and quarantine tanks where only a minimal of Ozone would be desired.
