AQPET AQ-CO2 Indicator Permanent test for monitoring the CO2 level in freshwater aquariums

AQPET AQ-CO2 Indicator (Permanent test for the monitoring of the co-level level in freshwater aquariums), is an essential device for those who manage a planted aquarium with co-edge spread.
The system consists of a glass / acrylic body equipped with a suction cup for fixing the inside to the tank and a segment to accommodate the indicator solution.

Principle of operation

Inside the acrylic bubble, once positioned in the tub, it remains air that communicates with the surrounding water through a small opening. The dissolved co-delivered in the indoor air by lowering the pH, which activates a color reaction in the indicator solution.
The detected color indicates:

• Blue → co₂ too low

• Green → co₂ in the optimal range (about 20-30 mg / l)

• Yellow → excessive co₂

Main features

• Passive operation without power

• Slow but stable chromatic change

• Reliable reaction indicative of the dissolved co-level level

• Easy installation by suction cup

• Suitable for long term monitoring with reagent replacement every 4-5 week

Main advantages

• Continuous and visual monitoring of the level of co₂, without electronic equipment

• Indispensable to ensure optimal conditions of plant growth in plans co₂

• Cheap, simple to use and maintain

• Reduction of the risk of problems related to incorrect levels of co₂ (stress or toxicity for fish and invertebrates)

Practical tips

• Install the indicator on clean glass and slightly above half of the aquarium height, away from the direct diffusion of co₂ to avoid altered readings

• Read the color after at least 4-6 hours from the change of the indicator solution

• If blue → increase slightly issue co₂; If yellow → reduce flow; If Green → Keep current cojection setting

AQPET AQ-CO2 Indicator It is the ideal tool for continuous visual monitoring of the level of carbon dioxide in freshwater aquariums. Combined with the reactive solution AQPET AQ-CO2 Solution, allows a simple but accurate management of the co₂ system, favoring the well-being of the aquatic flora and plants.
