Dr. Tank CO₂ Fertilizer Tabs – Effervescent Carbon for Optimal Plant Growth

Dr. Tank CO₂ Fertilizer Tabs provide an easy-to-use, effervescent carbon source that enhances plant growth through improved photosynthesis. These tablets release CO₂ directly into your aquarium, supplying essential carbon for lush, vibrant aquatic plants. In addition to CO₂, they contain an inorganic carbon source that continues to support photosynthesis even after the effervescent effect subsides.

Key Features:

Boosts Photosynthesis & Growth – Provides a steady carbon supply to enhance plant health and vibrancy.
Effervescent CO₂ Release – Tablets actively dissolve, releasing CO₂ for approximately 20 minutes.
Long-Lasting Carbon Support – Contains an inorganic carbon source for sustained benefits even after bubbling stops.
Flexible Use – Can be used alone or with a CO₂ system for more intensive plant care.

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.
