## Summary description

sera CO2-Tabs plus are designed for aquariums to provide a steady supply of carbon dioxide. Each pack contains 20 tablets that dissolve slowly, ensuring a consistent CO2 level for healthy plant growth. Ideal for planted aquariums, these tabs enhance photosynthesis and overall aquatic health.

## Long description

sera CO2-Tabs plus are compact, slow-dissolving tablets formulated to supply a steady source of carbon dioxide for freshwater aquariums. Each pack contains 20 tablets designed to release CO2 gradually, supporting photosynthesis and promoting healthy, vigorous growth of aquatic plants. The product is intended for planted aquaria where controlled and reliable carbon supplementation improves plant color, growth rate and overall tank stability.
Advantages
These tablets provide a consistent CO2 release without the need for complex pressurized systems, making them suitable for aquarists seeking a low-maintenance carbon source. Their slow dissolution profile helps maintain more stable CO2 levels compared with single-use, fast-dissolving additives. The tablets are calibrated for aquarium use and integrate easily into routine maintenance schedules.
Suitable for
Freshwater planted aquariums requiring supplemental CO2
Small to medium-sized tanks where pressurized CO2 systems are impractical
Hobbyists looking for an easy-to-dose carbon source to improve plant growth
Temporary CO2 supplementation during plant propagation or recovery
Key specifications
Form: slow-dissolving effervescent tablets
Quantity: 20 tablets per pack
Intended use: supplemental carbon dioxide for freshwater planted aquaria
Delivery: gradual CO2 release to support photosynthesis
Compatibility: suitable for typical aquarium water parameters used in planted tanks
How to use
Place one tablet directly into the aquarium water according to tank size and plant density; observe the tablet as it dissolves and follow routine water monitoring to assess CO2 effect. Replace tablets at intervals consistent with dissolution time and observed plant response. Do not exceed the recommended frequency for your aquarium size; combine with appropriate lighting and nutrient dosing for balanced plant growth.
Usage recommendations
Use sera CO2-Tabs plus as part of an integrated plant care routine: monitor plant appearance, adjust dosing frequency to avoid CO2 fluctuations, maintain adequate fertilization and lighting, and ensure regular water testing to keep parameters within safe ranges for fish and plants.
