Temporarily Out of Stock

The latest in BioPellet Reactor design from AquaMaxx. The unique flow pattern of the Omega helps to keep the biopellets in suspension, creates a gentle tumbling and eliminates clumping. The low pressure design also allows for the use of an energy-efficient pump and helps extend pump life. Maintenance requirement is also greatly reduced by the convenient filling port.

Controlling nutrients inside our aquariums is one of the keys to preventing nuisance algae growth. The AquaMaxx Omega BioPellet Reactor is a finely-tuned fluidized filter designed to help hobbyists remove nitrates and phosphates from reef aquarium systems.

AquaMaxx Omega biopellet reactors are computer designed, precision-cut and made of polished A-class acrylic. All AquaMaxx media reactors are rigorously tested to ensure reliability, efficiency and affordability.

Adding a biopellet reactor to your reef aquarium filtration system will improve the water quality for fish and other marine life. Biopellets initiate a more efficient denitrification process that removes nitrate and phosphate from aquarium water to prevent algae growth or harm to invertebrate and coral.

The AquaMaxx Omega BioPellet Reactor also includes a high-quality Sicce Syncra pump. The Italian-Made Sicce pump is quiet, energy-efficient and durable. This reactor and pump combination offers hobbyists unparalleled performance and reliability.

Broken with no support

Pros: works great until it breaks

Cons: Aquamaxx will not even respond to email requests for support

I purchased this reactor 6 months ago and as far a biopellet reactor goes, it is awesome. What is NOT AWESOME is that during routine cleaning, the acrylic tube that the Sicce pump mounts to broke it's cheap weld and came free from the reactor. To be clear, the tube did not break, the weld that holds the tube to the reactor broke. I sent multiple emails to Aquamax asking for warranty support and haven't gotten a single response.. I cannot recommend a product that a company will not stand behind on a clear defect that should be covered during the advertised warranty period.

Best reactor

I have this on my 300 gal and it’s got 1000ml of biopellets in it and I had to turn the pump down and it still tumbled better than any reactor I’ve ever seen.

Keeps the pellets spinning and tumbling

Pros: Keeps pellets moving without any clumping or dead spots

Cons: Occasionally the output filter plugs with smaller pellets

This is a new approach to keeping the pellets moving by blowing them with water to constantly keep them in motion. I’m very pleased with the performance. The only troubling spot is that every couple of days after starting and using existing pellets from my other reactor is that the smaller pellets eventually plug the output filter. To resolve I just turn off the pump and jiggle the entire unit to cause the pellets to release from the output filter or I open the top plug and insert a bottle brush to clean the pellets off. I hope after a couple of weeks this will stop. Overall this seems to be one of the best reactors for keeping the pellets tumbling without clumping.

I would recommend this product.

Hands Down the Best Biopellet REactor

Pros: No clumping

Cons: NONE

For about a year, I have been trying to live w/ the constant clumping in my $250 reactor by CV. I finally gave up and bought the Omega-2. I wish I hadn't waited so long, this reactor is awesome. Tumbles 3 cups of pellets no problem - that's double what I was able to tumble with my CV reactor. The best part, the Sice pump is easily serviced and cheap to run. I had to use a 1,200 GPH pump on my CV reactor just to get 1.5 cups of pellets to move. Easily fits into the first chamber of my Trigger 39 sump even with a Vertex Omega 180i skimmer. I couldn't be happier, this reactor is the bomb if you use biopellets.

Good reactor but minor problems

Pros: Good design for tumbling the pellets

Cons: Tube for connecting the pump is too short; Fill plug easily dislodges

Reactor works well regarding tumbling of the pellets. However, the connection for the pump is too short. I had to use a zip tie to hold the pump onto the reactor. Additionally, the plug at the top of the reactor can come off easily. Does a good job of reducing nitrates

Great Concept

Pros: Easy to Add Media, Great Tumble

Cons: Pump Clogs Easily

The Omega-2 Biopellet Reactor is a very innovative design that eliminates the biggest problem with polymer media. Most reactors cannot generate enough flow to keep the biopellet tumbling and the bacteria on the media ends up dying and polluting the system. This reactor has no problem with flow! Unfortunately, it creates a separate issue that has to be addressed. The pump provides so much flow when using 1 cup or less media that the bacteria gets blasted off of the pellets. The flow rate also grinds the pellets down and breaks them a part. To prevent this you should install a ball or needle valve between the pump and reactor or on the reactor outlet. Just be sure you don't slow down the pellets too much or they won't tumble. I would also recommend you use a funnel to add pellets or they'll get everywhere!
