Ozone is an extremely aggressive gas which - if not used properly - can damage one's
health. For this reason, ozone should never be breathed in directly.
In addition, at high doses ozone can damage the skimmer.
The dosing of ozone must be set so that no free ozone can be discerned on the skimmer lid.
Deltec skimmers can be operated with between 20 and 50 mg/hours of ozone per pump. An
ozone-resistant T-piece is placed in the air hose above the skimmer pump. The free end of
the T-piece is connected to the ozonizer by means of an ozone-resistant hose. The air valve
of the skimmer must be throttled until air is independently sucked through the ozonizer.
