🧪 Why Add CO2?

Aquatic plants thrive on carbon dioxide (CO2), but natural CO2 levels in aquariums are very low. Adding pressurized CO2 allows your plants to photosynthesize efficiently, grow lush and healthy, and outcompete algae. Without CO2, even with high lighting, plants may struggle to grow and algae may take over.


📏 Additional Specifications:

  • Output Pressure Gauge: 0–50 PSI

  • Pressure Relief Valve: 51–53 PSI

  • Compatible With:

    • Standard CO2 cylinders (CGA-320)

    • Paintball tanks

    • UNS Disposable CO2 cartridges


🌱 What Else You’ll Need:

  • CO2 Tubing

  • Diffuser

  • Check Valve


Upgrade your planted tank with reliable CO2 control—the UNS Mini Dual Stage CO2 Regulator is the compact, all-in-one solution trusted by aquascapers worldwide.

Beautiful addition to my reef!

The fish arrived in perfect condition. Packaging was triple insulated with heat packs. Acclimation was smooth and it was eating frozen mysis within 2 hours of introduction. AquaEditorial never disappoints.

Good but picky eater

Beautiful specimen, arrived healthy. Takes a while to adjust to new food but eventually started eating pellets. Great addition to my South American cichlid tank.

FAQs

Emily R.·2 days ago

What temperature should I keep the tank at for this fish?

Betta USASeller·replied

Great question! We recommend maintaining a water temperature of 82–86°F (28–30°C). Discus are tropical fish and thrive in warm, stable water conditions. A reliable heater with a thermostat is essential.

Michael T.·5 days ago

Can I keep this with other fish in a community tank?

Betta USASeller·replied

Yes! Discus are peaceful and social. They do best with calm tank mates like Cardinal Tetras, Rummy Nose Tetras, and Corydoras Catfish. Avoid aggressive or fast-moving fish that may stress them.

Sarah L.·1 week ago

What size tank do I need for a small group?

Betta USASeller·replied

We recommend a minimum of 55 gallons for a small group of discus. They need spacious aquariums with open swimming areas, live plants, driftwood, and gentle filtration.

David K.·1 week ago

What should I feed them?

Betta USASeller·replied

Discus are omnivores and benefit from a varied diet. We recommend high-quality discus pellets, frozen bloodworms, brine shrimp, and beef heart mixes. A varied diet helps maintain vibrant coloration.
