About this item

Description

Achieve superior CO2 diffusion with the UNS Pro Inline CO2 Diffuser, designed for seamless integration into your filtration setup. This premium diffuser connects directly to your canister filter’s tubing, ensuring efficient and uniform CO₂ distribution throughout your aquarium.

Unlike existing Inline CO2 diffusers, the UNS Pro Inline CO2 Diffuser does not impede your filter's flow by placing the ceramic plate on the side of the diffuser. This makes the ceramic plate easy to replace and clean as well.


Key Features

  • Fine ceramic disc provides ultra-fine CO2 bubbles, maximizing gas dissolution and minimizing wasted CO2.
  • Available in 12mm (1/2"), 16mm (5/8"), and 20mm (1") tubing sizes for compatibility with a wide range of external filters.
  • Fits perfectly into the UNS Delta and Blitz filter lineup.
  • Installs outside the tank, eliminating visual clutter from your display tank.
  • Built from high-quality, corrosion-resistant materials for long-lasting performance and easy maintenance.
  • Ensures stable CO₂ levels to support lush plant growth and balanced water chemistry.
  • Can be used inside UNS Holding systems to reduce clutter and provide superior CO2 coverage.
Whether you're a seasoned aquascaper or just starting your planted tank journey, the UNS Inline CO2 Diffuser offers a clean, efficient, and professional-grade solution to elevate your aquarium’s potential.

Compatible with pressurized CO₂ systems only.
For use with canister filters or UNS Plant holding systems only.
Not suitable for use with sponge or internal filters.

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.
