AquaMaxx BioMaxx BioPellet Reactor Information

Product Manuals & Documentation

AquaMaxx BioMaxx BioPellet Reactor

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

AquaMaxx BioMaxx bio pellet 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.

The AquaMaxx Bio Pellet Reactor utilizes a fluidizing plate to keep biopellet media suspended and evenly dispersed. The upward flow design provides maximum contact time between your aquarium water and the bio pellets inside the reactor. The Aquamaxx BioMaxx Biopellets Reactor also includes a special plate on the lid to keep media within the reactor without the need for sponges.

Adding a bio pellets 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 BioMaxx BioPellet Reactor requires a small pump/powerhead and tubing to push water through the reactor (sold separately). You can plumb the reactor using ¾" flexible tubing. Using a ball valve is highly recommended because it will allow you to dial-in the correct flow rate. A flow rate of 200-300 gallons per hour (GPH) is recommended for the AquaMaxx BioPellet Reactor. A flow rate of 300-600 GPH is recommended for the AquaMaxx BioMaxx XL BioPellet Reactor. Exact flow rates required to tumble the media will vary based on how much media is being used.

An optional hang-on adaptor (sold separately) is available for additional mounting configurations. For best results, use AquaMaxx BioMaxx Plus BioPellets or similar biofiltration & nutrient control filter media.

All AquaMaxx products carry a 90-day manufacturer warranty and include detailed instructions and diagrams to help hobbyists get up and running immediately.

XL Model - Great Flow!

Comments: My previous media reactor had issues with sufficient flow and bio pellet clumping. After a couple of years, I decided it was time for a change. I researched several bio pellet reactors, and purchased a AquaMaxx BioMaxx XL for my 120g reef. After an easy load of bio pellets and installation (external to sump/refugium), I hooked up my Mag 7 pump (700 gph), which was barely sufficient to run my previous reactor, and realized that it was "way" too much flow. The pellets were swirling clear to the top of the reactor (3 cups of pellets). I backed off to a Mag 2 pump (250gph), and it is perfect! Very nice laminar flow, and the pellets form a nice circular vortex. No problems whatsoever with clumping. I tightened the screws on the top, and checked the hose fittings, and have had absolutely no issues with leaking (as other reviews indicated). Very pleased!

Comments: This is the best bio pellet reactor I've witnessed in action. Around 150gph will tumble 250ml of pellets perfectly. No need to blast the pellets and cause them to break down prematurely with this unit.

Spins 4 cups with ease

Comments: I bought the Aquamaxx XL to replace a Reef Octopus BR-140. When I bought the BR-140 I purchased an Eheim Compact+ 2000 Pump to power it. This did not work. I had run the BR-140 with my spare Iwaki return pump to get it to float 4 cups of pellets. This worked fine and I got great results from running bio pellets. But the noise from running two huge return pumps, one for the BR-140, and one for my whole 175 gallon tank. Pretty silly. Now with the Aquamaxx XL I can spin the same 4 cups with ease using my Eheim pump. The design creates a spinning action in the chamber that keeps the pellets suspended with a fraction of pump strength of other reactors. So impressed with Aquamaxx design I bought there protein skimmer too.

Comments: Very good construction that focuses on ease of maintenance. the input swirly thing completely disassembles to clear debris easier than anything I have seen. I can pull it apart, clean and reassemble in under 10 minutes. I have owned one since Christmas 2013 and just set up my second on another system.

Comments: I have used four different biopellet reactors and this is by far the best. It is also one of the least expensive. The reactor is designed to spin the pellets and this works extremely well and you can use a less powerful pump and still get results. There are no clumps of pellets or dead spots with this reactor. I like it even better then the much more expensive recirculating models from other companies.

Comments: This product is very easy to use simple to set up nothing but the best quality looks like so far. There's not much to this product and it is very easy to set up with minimal amount of plumbing. Does exactly as it states. Need little to no fine-tuning. Extremely easy to clean. Very simple design.

Comments: this unit was purchased for my 111 gal densely stocked mixed reef with a heavy population of sps. since bio-pellets came on the scene, i've tried nearly a dozen different reactors. i've used everything from bargain models from well-known reefing companies to expensive hand-mades by boutique builders - all with mixed success. all reactors were able to lower my nitrates from low to nil, but even with near constant tinkering, adjustments, and borderline-rebuilds - i encountered frequent pellet-clumping, media-screen clogging, and other headaches. so i was skeptical of this product due to its low price. and when the box arrived, emblazoned with "made in taiwan," i nearly returned it without even breaking the packing tape. i'm pleased to say that i have been entirely disabused of doubt. i never pay much mind to reviewers who've only owned a product a short while, and if you share my opinion on this matter, please understand that pellet reactors aren't rocket science. if the pellets tumble well, the reactor is working. this reactor is working exceptionally well. the unit is robust, attractive, and well-built. more importantly, using the same plumbing, (used) media, and pump as its predecessor which never fluidized the pellets well (and cost nearly 3x as much as the aquamaxx), i have perfect fluidization now. furthermore, i was so confident in this product after only a few days, that i decided to try to add more pellets. the aquamaxx is now fluidizing twice the volume of media as my old reactor which was significantly larger, in addition to being much more expensive. this reactor is a home run. i use a mix of Vertex and Two Little Fishies media, Tygon tubing with a 5/8" ID, and a Danner Mag-Drive Supreme 5 pump.
