Aquarium Co2 kits are used to provide the tropical aquarium plants with CO2. Tropical plant needs Co2 to grow and thrive. Tropical Co2 kits ensure that your tropical plants recieve the appropriate amount of co2 to grow.
Aquarium CO2 kits come in 4 basic Co2 types.
The gas bottle aquarium CO2 kit uses a compressed form of CO2 and is delivered via a CO2 regulator into a buble counter which measures out the amount of CO2 delivered into the aquarium.
The disposable co2 aquarium system uses much the same system exept the CO2 bottle is meant to be recycled after use and not refilled.
The fermentation aquarium CO2 uses a chemical process to give off CO2 which is delivered via air hose into the aquarium.
A tablet CO2 system for the tropical aquarium uses a tablet which when mixed with aquarium water delivers CO2 into the aquarium.
If a tropical aquarium has good CO2 then the quality of the aquarium plants will be greatly increased and you will find your tropical aquarium plants thriving for years to come. |
