Co2 Drop Checker Replacement Solution by Co2Art


15ml Premixed Drop Checker Solution by Co2Art

Monitoring and maintaining the correct Co2 levels in your planted aquarium is vital. The drop checker is a reservoir for an indicative fluid that tells you whether you have too much, too little or the correct levels of Co2 for your plants to grow, and that is a safe level for fish. Replacing the solution in your drop checker on a regular basis will help you maintain the correct levels of Co2 in your tank.
