[Updated] Best Aquarium Media Reactor in 2021 (REVIEWS)

If your aquarium filter cannot keep up with your aquarium, you have probably tried several solutions. But believe it or not, flushing or replacing the filter media can hurt more than it can help. It can be difficult to recover from disrupted colonies of beneficial bacteria.

A media reactor (also called a phosphate reactor) is an advanced type of chemical filtration method, which you can use for both freshwater and saltwater tanks. They are generally cylindrical in design and you can fit any filter media you like before submerging it in the water. Your pump then allows the water in the tank to flow through the pipe so that the water is properly filtered.

What is a Media Reactor?

Everyone knows that filtration is one of the most important parts of aquarium maintenance. Poor water quality can have a profound effect on your fish and plants, but maintenance can be difficult.

Filters need to be rinsed every few weeks and the filter itself needs to be replaced every month. The problem with this is that it disrupts a significant portion of the beneficial bacteria colonies that are needed to maintain the nitrogen cycle in the tank.

Most beneficial bacteria live in the substrate in your tank, but filter media is your next favorite place to grow. Rinsing and replacing removes these colonies and takes time to reestablish.

A simple way to avoid this problem is to use a media reactor. A media reactor is an advanced filter with a tube-shaped design. The water moves through an inlet to the bottom of the reactor and then rises through the filter media before returning to the tank.

This upward filtration is much more effective than a typical filter mainly because there is more surface area, which means more contact between the water and the filter itself.

 

Are Media Reactors Necessary or Not?

Depends.

If your regular filter seems to work fine, you may not need a media reactor. It all depends on the size of the tank and what it contains.

Sometimes it’s helpful to start with a regular filter and add a media reactor if you feel you need one. You can always start with a standard filter, see how it works, and make the necessary changes in the future with a media reactor.

That said, if you have a large reef tank, media reactors are often worth the investment. Any tank with many needs and a variety of plants, corals and fish can benefit from the increased filtration media reactors provide.

 

How to Install Media Reactor?

Installation varies slightly from model to model, but there are a few basic things they all have in common.

1. Find a suitable location for the reactor. Some can be placed inside and others can be hung on the back of the tank, but you should place it in an easily accessible place.

2. Make sure the hose is properly connected and the cable is secured in place. Some of these reactors come with tubes, some don’t, but it’s a good idea to have extra tubes on hand regardless of the different installation scenarios.

3. In particular, connect the inlet hose to the pump and place the pump in the tank.

4. Then connect the outlet hose to the reactor. If using a sediment filter, place it at the end of the exhaust tube.

5. Remove the cap and fill it with your preferred filter media. It is very important to follow the manufacturer’s instructions for aquarium size, flow rates and other precautions for each type of medium.

6. Place sponges and strainers on and under other media.

7. Replace the cap and turn the pump on.

Once your reactor is up and running, regular maintenance is important to keep it running efficiently.

Some maintenance services are:

  • Disconnect the power supply and then remove the pump from the tank for cleaning.
  • Rinse the sponges and strain.
  • Only clean the impeller with water. Never use soap or detergent.
  • Use a small brush to clean the inside of the motor housing.
  • Clean the pump, impeller and inlet every three to four weeks.

 

Factors to consider before choosing the Best Aquarium Media Reactor

Size / Capacity

There are many sizes to choose from, so you should choose the one that is compatible with your tank size. Since most manufacturers design different sizes for different types of tanks, it is easier for you to select.

Bomb

This is one of the essential parts of an aquarium reactor. Therefore, you should choose a brand that produces a reliable and stable pump. You can also buy a reactor that does not contain a pump, and you can buy the pump separately.

The pump is like a vital organ because it does all the work to bring the water directly into the reaction chamber. So before you buy the pump separately or together with the reactor, you should read the reviews carefully.

In this way you also know the meaning of the pump and you get an idea of ​​which brand you should choose for a stable pump.

Design and quality

As we mentioned before, reactors are a chamber, a pump and some valves that will help you catch the water flow in the chamber or enter the chamber to charge or change the medium.

Therefore, one of the most important features when choosing a suitable aquarium reactor is to see if it is made of quality materials and built with a solid finish.

Budget

When it comes to choosing the best aquarium reactor, in addition to its features, you should also consider its cost. However, an essential factor to verify is to see if the desired model includes a pump.

This is because buying an expensive aquarium reactor that does not have a pump will cost you more in the future because you have to buy it separately. But this also does not mean that you should select an overpriced model with a pump.

 

Conclusion

Sometimes a normal aquarium filter is just not enough to meet the requirements of your aquarium. If so, a media reactor is a quick and easy way to make sure your water is clean and balanced.

There are plenty of great options out there whether you are looking for the best nano medium reactor for a nano tank or something that will fit in your 150 gallon saltwater tank. We hope the information in this guide helps you choose the best option for you.
