Carbon dioxide test

Carbon dioxide (CO₂) is essential for photosynthesis in aquatic plants. If it's too low, plants stagnate and algae proliferate. If it's too high, fish risk suffocation. The JBL CO₂ Test precisely controls the amount of dissolved CO₂ in the water, based on pH and KH values, to achieve an ideal balance.

✅ The benefits of a good dosage of CO₂

1. Effectively stimulates the growth of aquatic plants
2. Allows precise adjustment of CO₂ injection (JBL CO₂ system or other)
3. Preserves fish health by avoiding toxic excesses
4. Maintains a stable pH through balanced carbonate hardness (KH)
