Why does BRS recommend this?

When it comes to ozone reactors the Poseidon is a class leader by producing by constantly outperforming its competition.  With an adjustable output, and patented Cold Spark Corona Discharge not many other ozone generators come close to its performance in its price range.  With serviceable parts, and great customer service, Ozotech only does ozone and they do it very well.


Input - 3/16"
Output - 3/16"


Bulk Reef Supply considers Ozotech to be the leading brand of ozone products available to the aquarium industry for a number of reasons:

  • Ozotech only does ozone and they do it well. Their products are not a sub line of an aquarium company whose specialty isn't ozone.
  • The Corona Discharge unit is replaceable by the aquarium hobbyist in just a few minutes, where other brands require the user to buy a new unit when the corona discharge wears out.
  • 1 year warranty
  • Ozotech has fantastic customer service. Troubleshooting and customer service phone calls and emails are answered promptly.


Using Ozone will have the following benefits in the aquarium:

  • Healthier corals and increased polyp extension due to the oxidation and breakdown of corals defensive toxins
  • Consistently clear water and proper light penetration due to the oxidation and breakdown of color pigments.
  • Increased skimmer efficiency due to ozone causing waste particle to attract each other creating larger easier to filter particles.
  • Oxidation and breakdown of fish waste and uneaten food.

Safety Note We strongly recommend using ozone in conjunction with an ORP controller to ensure it is used safely. It is extremely important to use carbon on both the air and water output of the reactor or protein skimmer. Ozone is not healthy to breath in large quantities so if you can smell it in your home at all please change the carbon.

Product Questions

What size are the input and output connections?
Question by: David Holbrook on Jan 30, 2023, 8:23 AM
Will I need an air pump to use this in conjunction with a reefoctopus 150ext skimmer or will it draw enough air through it on its own?
Question by: Will on Jan 24, 2018, 5:56 PM
The skimmer will pull more than enough air through the ozone generator. : )

Hi - will this require an air dryer for the input? Would be running inside the cabinet of a Red Sea Reefer.
Question by: Bryan Mack on Nov 14, 2016, 2:58 PM
Great question! It is highly recommended to use an air dryer for these Ozone Generators, especially with them being installed in a high humidity environment such as under the stand. :-)
