The use of ozone in seawater filtration is a powerful means of achieving the crystal clear, "fish floating in air" effect seen in the world's most beautiful marine aquaria.  An extremely powerful oxidizing agent, ozone will essentially "bleach" your seawater clean when used in a controlled environment in a safe and effective manner.  Coupled with an efficient protein skimmer, ozone can help improve water quality by breaking down large organic molecules into components more suited to skimming or usable by bacteria.  Ozone users frequently report an increase in skimmer productivity and almost always better water clarity and overall system health.

Our new, version 2.0 Mutiny ozone reactor is designed to react seawater with an ozonated air environment.  The efficiency of this process is optimized by balancing water throughput with contact time, which is greatly enhanced by the use of a specially modified ozone-safe Sicce needlewheel recirculating pump.  Water and ozone are forcefully mixed inside a custom designed diffuser chamber, then dispersed over a bed of thin HDPE ribbon media in an atmosphere of ozonated air.  The high surface area of this media allows much better gas exchange and oxidation of organic material than simply bubbling ozonated air through a column of water, as when using ozone in a protein skimmer.  After aquarium water passes through and exits the reactor chamber, it runs through a carbon post filter which strips out all remaining ozone and any by-products of the oxidation reactions.  This effectively neutralizes the smell in both the effluent air and water, making both safe for fish, pets, and people.

We have chosen the variable output Ozotech Poseidon 200 as our recommended ozone generator.  This unit has proven to be a reliable and high quality machine and is user serviceable as well.

Technical Data

Footprint with connected carbon reactor: 12" x 7" x 21" tall.  

Carbon reactor can be placed remotely for more flexible footprint options.

What's Included

Comes with Ozone reactor, HDPE media, air pump*, recirculating pump, several options for carbon reactor and enough carbon for 2 months of operation. Ozone generator and feed pump are required for operation but may be purchased separately.  

4 feet of tubing for reactor hook up plus flow control valves are included, all ozone safe tubing for water connections is included.  

Ozone safe air tubing plus high quality ozone safe check valve are included with the ozone generator.  If you are using your own generator you will want to plan for connection to a 3/16" barb at the pump.

 *Air pump is included for USA customers only.  Please contact us for other countries before placing an order

Let it rain

Was great once I knew the pumps needed to be started in a different order.i love this this

Superior quality

Finally got to run ozone in the most efficient way , had some difficulties in tuning it at first but at last reached the crystal water affect , noticed some boost in fish health and algae decreased significantly . amazing product !!


Mutiny I Ozone Reactor

Upon first deciding to run ozone on my tank, the first place I turned was Avast. Due to their high construction quality, clever designs and superior customer service, my sump has become essentially a showcase for Avast Marine products. The Mutiny reactor has only bolstered my confidence further. Since installing it, along with an Avast MR5 reactor, filled with lignite carbon, my ORP level has gone from the low 220s up to around 330 and my tank looks great. Customer service was excellent as usual, helping me get everything running properly. There aren't many commercially available ozone reactors out there, but I can't think of any reason why one wouldn't choose this one. Thumbs up!


Mutiny Ozone Reactor

Avast quality and great customer support that I've come to expect from Avast Marine. I got the Mutiny I with an MR5 inline filled with carbon to scrub excess ozone and it works great. I run Bituminous carbon in the reactor with some filter media to keep it in the reactor. Something like Rox 8 is too small and will pass through the filter plate holes.
