Use the Colombo CO2 Indicator to monitor the CO2 level in the aquarium. The ideal CO2 level for aquarium plants is between 20–30 mg/l. Combine with Colombo Flora Grow for complete plant nutrition.
💡 Tip
Add the Colombo CO2 Diffuser 3 in 1 for a clearer CO2 system — check valve, bubble counter, and diffuser in one compact device.
❓ Frequently asked questions
How long does a refill bottle last?
The Colombo CO2 Basic Refill contains 12 grams of CO2. The duration depends on the aquarium size and the set dosage.
Is CO2 injection necessary for aquarium plants?
Not mandatory, but highly recommended for faster and healthier plant growth. Without a CO2 system, Colombo Flora Grow Carbo is a good alternative.
