ISTA Solution for CO₂ Indicator
ISTA Solution for CO₂ Indicator is a replacement indicator solution designed for use with aquarium CO₂ drop checkers and CO₂ indicators. The solution changes colour based on the amount of dissolved carbon dioxide in the aquarium, providing a simple visual reference for monitoring CO₂ levels in planted tanks.
Maintaining a stable CO₂ level is one of the most important parts of running a healthy planted aquarium. This indicator solution makes it easy to check whether your CO₂ injection is too low, within the desired range, or potentially too high.
Simple Visual CO₂ Monitoring Use with a compatible CO₂ indicator or drop checker to quickly monitor dissolved CO₂ levels by colour.

Important CO₂ indicator colour changes are not instantaneous. Allow sufficient time for the solution to respond before making additional adjustments to your CO₂ system.
Aquascaper's Tip Make CO₂ adjustments gradually rather than making large changes at once. Stable CO₂ levels are generally more beneficial to aquarium plants than constantly chasing a specific colour throughout the day.
