Ozone Generator with Air Drier

The Reef Octopus RSO-25 Ozone Generator with Air Drier raises your aquarium's ORP, boosts dissolved oxygen, and helps break down dissolved organics that leave water looking yellow or tinted. The built-in air drier keeps humidity out of the ozone-producing chamber for more consistent, reliable output.

• Benefits: higher ORP, increased oxygenation, clearer water, reduced pathogen load
• Includes: integrated air drier for consistent ozone production

Important: ozone should be dosed through a dedicated reactor (such as the Octopus OR-150) rather than injected directly into a skimmer, and should always be run with an ORP controller and a carbon-scrubbed exhaust — overdosing ozone can harm fish and corals. Never run an ozone generator without proper monitoring equipment.

Compatible with: dedicated ozone reactors such as the Octopus OR-150 (sold separately).
