JBL PERMANENT CO₂ TEST – Continuous CO₂ and pH Monitoring for Freshwater Aquariums
JBL Permanent CO₂ Plus pH Test offers real-time, ongoing monitoring of carbon dioxide levels and pH in freshwater planted aquariums. This practical and reliable test provides a constant visual indicator of CO₂ concentration, helping aquarists maintain stable, plant-friendly water conditions.
Using the test is simple: fill the clear test chamber with the reagent and attach it to the inside of the aquarium glass using the included suction cup. The solution’s color changes based on the CO₂ content and pH. By comparing the color to the adhesive reference chart, you can easily determine whether CO₂ levels are optimal and adjust dosing accordingly.
This test is particularly useful in planted tanks, where adequate CO₂ is crucial for photosynthesis and healthy plant growth. It also aids in preventing pH imbalances and ensures a stable environment for fish and invertebrates.
