The Dymax CO2 Indicator Solution is a refill solution for CO2 drop checkers that changes colour to show the CO2 level in your aquarium.

Key Features

• Use in a drop checker such as the Dymax Crystal CO2 Indicator

Good To Know

• Drop checkers react slowly — read the colour about 2 hours after the CO2 turns on.
• Confirm your CO2 level with a drop checker — green is the usual target, yellow means too much, blue means too little.
• Replace the solution every few weeks, or whenever the colour looks faded.
• Keep out of reach of children and pets.
