If your aquarium filter just can’t keep up with your tank, it’s likely you’ve tried a number of solutions.
But, believe it or not, rinsing or changing filtration media can hurt more than it can help.
The disruption to the beneficial bacterial colonies can be hard to come back from.
One way to combat this is to use the best aquarium media reactor, a tube-like setup that uses upward flow for effective and efficient filtration.
A media reactor might be just the boost your struggling aquarium needs to get back on track.

What is a Media Reactor?
Everyone knows that filtration is one of the most important parts of maintaining an aquarium. Low water quality can have a profound effect on your fish and plants but maintenance can be tricky.
Filters should be rinsed every few weeks and the filter itself should be replaced every month. The problem with this is that it disrupts a significant part of the beneficial bacterial colonies that are needed to maintain the nitrogen cycle in the tank.
Most beneficial bacteria live in the substrate of your tank but the filter media is their next favorite place to grow. Rinsing and replacing it eliminates these colonies and it takes a while for them to reestablish.
An easy way to avoid this problem is to use a media reactor. A media reactor is an advanced filter with a tube-like design. Water moves through an inlet to the bottom of the reactor then up through the filtration media before being cycled back into the tank.
This upward filtration is much more effective than a typical filter primarily because there’s more surface area which means more contact between the water and the filter itself.
Are Media Reactors Necessary or Not?
If your regular filter seems to be doing the job, you may not need a media reactor. It all depends on the size of the tank and what’s inside of it.
Sometimes, it’s beneficial to start with a regular filter and add a media reactor if you discover that you need one. You can always start out with a standard filter, see how it does, and make the changes you need with a media reactor down the line.
That said, if you have a large reef tank, media reactors are often worth the investment. Any tank that has a lot of needs and a variety of plants, coral, and fish could benefit from the increased filtration that media reactors give.

4. Accel Aquatics Biopellet and Filter Media Reactor
If you’re looking for a reactor that’s designed specifically for bio pellets, take a look at this one from Accel Aquatics. It was made to fluidize bio pellet filter media without using a strong, high-flow water pump.
How does it work? There’s a special flow accelerator inside the reactor that increases turbulence and strong water movement to keep the bio pellets moving. An inverted cone bottom keeps the media from clumping together or settling to the bottom.
You can use this reactor with other filter media, too, including carbon or GFO, just use a water pump that can handle to flow requirements of the filter media you choose.
The inlet can be repositioned so it can be positioned properly in your tank and it includes a holder so you can hang it off your tank if you prefer.
- This reactor is specially designed for bio pellets but can be used with your choice of filter media.

How to Install Media Reactor?
Installation varies slightly from model to model but there are some basic things that they all have in common.
1. Find a suitable position for the reactor. Some of them can be placed inside and some hang on the back of the tank but you should place it so it’s in a place where you have easy access.
2. Make sure the tubing is attached properly and cable tied in place. Some of these reactors come with tubing, some don’t but it’s a good idea to have extra tubing on hand no matter what to allow for different installation scenarios.
3. Specifically, connect the intake tube to the pump and place the pump in the tank.
4. Then, attach the output tubing to the reactor. If you’re using a sediment filter, place it at the end of the output tubing.
5. Remove the lid and fill with your favorite filter media. It’s very important to follow the manufacturer’s instructions for aquarium size, flow rates, and other precautions for each type of media.
6. Place sponges and strainers above and below other media.
7. Put the lid back in place then turn on the pump.
Once your reactor is up and running, performing regular maintenance is important to make sure it keeps running efficiently.
Some maintenance includes:
- Disconnect the power supply then remove the pump from the tank for cleaning.
- Rinse out the sponges and strainers.
- Clean the impeller using water only. Never use soap or detergent.
- Use a small brush to clean inside of the housing for the motor.
- Clean the pump, impeller, and intake once every three or four weeks.
Sometimes, a regular aquarium filter just isn’t enough to keep up with the requirements of your fish tank. If that’s the case, a media reactor is a quick and easy way to make sure the water is clean and balanced.
There are a lot of great options out there whether you’re looking for the best nano media reactor for nano tank or something that suits your 150-gallon saltwater tank. We hope the information in this guide helps you choose the best one for you.
