The media reactor can expand the surface area and contact time between the media and the aquarium water. 
Let’s introduce you to the various JNS media reactors:

​

​

• Multi-Use Media Reacto

They are accommodated with most media.
We have designed various types and capacities to fit your needs:
- in-sump: SIGMA-1 / SIGMA-2
​- in-sump (with magnet mount): FR-S / FR-M
- external: FR-1ES / FR-1E / FR-2E / FR-2ED
   Hang-on bracket for FR external: H-10
​- external (with hang-on-back design) FR-S

​

• BioPellet Media Reactor

We customize the media plate inside the reactor for bio-pellet to create a spiraling flow that keeps the media suspensive and maximum the contact surface. 
We have bio-pellet reactor: 
- in-sump: OMEGA-1 / OMEGA-2 / ALPHA-1 / ALPHA-2
- external: ALPHA-1E / ALPHA-2E

​

• Zeolite Reactor

Zeolite media can help you to create a more natural saltwater environment by removing any excess nutrients and organics from your aquarium water without removing vital trace elements. 
Zeolite media needs to be agitated every day. 
Try our JZR series zeolite reactors (JZR-1 / JZR-2) to make daily agitation easier.

​

• Calcium Reactor

Calcium is necessary for reef build.
Having a calcium reactor to take over annoying counting job for you. 
Check our T series calcium reactors: T-NANO / T-1 / T-2 / T-3
If you have needs of extension, second reaction chamber for T series is also available: T-X

​

• Nitratereductor

The nitratereductor creates a low dissolved oxygen environment with a very slow flow rate and grows the anaerobic bacteria that take nitrate as food.
And the Bio Balls included in the product provide the complicated passages to prolong the contact time for water and anaerobic bacteria. 
Traditionally we need to worry about the clogged problems in low flow rate reactors, clogging will grow cyanide which is poisoned. 
But JNS adds an inlet filter (for T, TS, TN series) and significantly reduces those problems!
Check our TN series nitatereductors: TN-1 / TN-2 / TN-3

​

• Sulfur Denitrator

​Sulfur denitrification was originally developed for the treatment of wastewater in water treatment plants. 
Nitrate (NO3−) is reduced and ultimately produces molecular nitrogen (N2) through a series of intermediate gaseous nitrogen oxide products. 
And now this technology has been utilized in the aquarium. 
Check our TS series sulfur denitrators: TS-1 / TS-2 / TS-3
