Description
The AQ-CO2 INDICATOR from AQPET is a precision technical device, designed to provide simple, continuous and visual monitoring of the dissolved carbon dioxide (CO?) concentration in any freshwater aquarium. Designed especially for densely planted aquariums, where the dosage of CO? is essential to promote photosynthesis and lush plant growth, this instrument allows you to regulate the delivery of CO? more safely and effectively , avoiding deficiencies or overdoses that are potentially harmful to the aquatic ecosystem.
Easy to install, discreet in design and free of electronic components, the AQ-CO2 INDICATOR represents a practical, economical and indispensable solution for any CO2 fertilization system, both in amateur tanks and in professional setups.
Visual chemical operation – immediate and continuous control, 24 hours a day
The heart of the system is a liquid-based indicator that changes color in response to the pH of the air in the device's chamber, which is directly influenced by the concentration of CO? dissolved in the aquarium water. The reactive liquid (included in the package) visually displays the level of CO? according to a standardized color scale:
- Blue ? CO level ? insufficient
- Green ? Optimal CO2 level
- Yellow ? CO level? excessive
This method allows you to:
- precisely regulate the diffusion of CO?, adapting it to the quantity of plants and the size of the tank;
- avoid risks to aquatic fauna , as an excessive presence of CO? can reduce dissolved oxygen levels, causing stress or suffering in fish;
- optimize photosynthesis , improving plant health and their ability to absorb nutrients, combat algae and produce oxygen.
Monitoring is continuous and passive : it does not require power supply, batteries or daily maintenance.
Compact and functional design – easy to install, simple to read
The body of the AQ-CO2 INDICATOR is made of transparent and resistant plastic, designed to ensure a long life even in aquatic environments with variable pH or with the presence of fertilizers. The device is equipped with:
- a soft silicone suction cup , which allows for firm and secure installation on any point of the internal glass of the aquarium (preferably in a clearly visible area but away from strong currents);
- a semicircular reactive chamber , with an opening facing downwards, which protects the liquid from direct contamination with water, maintaining the reading stable and accurate for several days.
The indicator is compatible with all types of freshwater aquariums and can be easily moved or removed for maintenance or re-setup.
Perfect for planted aquariums and professional setups with active CO2 system
The use of carbon dioxide in aquariums is a fundamental practice for:
- stimulate photosynthesis of aquatic plants;
- improve leaf growth, color and oxygen production ;
- maintain a stable biological balance within the tank.
However, the absence of a reliable visual monitoring system can lead to serious imbalances. The AQ-CO2 INDICATOR allows you to intervene in real time on the regulation of the CO? delivered, optimizing the results and minimizing uncertainties .
It is particularly recommended in:
- planted tubs with liquid fertilization and CO? in cylinders ;
- nano aquariums sensitive to concentration changes ;
- environments with high plant density , where the CO2 requirements are greater.
