You will need to purchase a separate CO2 indicator solution (such as a bromo blue or pH-based solution) to use with the checker. These are widely available at aquarium shops or online.\u003c\/p\u003e\n\u003ch4\u003eQ: What material is the drop checker made from, and is it safe for aquariums?\u003c\/h4\u003e\n\u003cp\u003eA: The drop checker is made from high-quality borosilicate glass, which is heat-resistant, chemically inert, and completely safe for use in freshwater planted aquariums. It will not leach any chemicals into your tank water.\u003c\/p\u003e\n\u003ch4\u003eQ: How does a CO2 drop checker work?\u003c\/h4\u003e\n\u003cp\u003eA: A CO2 drop checker works by trapping a small air bubble inside the glass chamber. CO2 from your tank water diffuses into this bubble and reacts with the indicator solution, changing its colour. Blue indicates low CO2, green indicates an ideal level, and yellow indicates excess CO2, allowing you to fine-tune your injection rate for optimal plant growth.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the drop checker compatible with all fish tanks?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The glass drop checker attaches to your aquarium wall via the included suction cups and is compatible with all standard glass aquariums used in freshwater planted tank setups.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Does the CO2 drop checker come with indicator solution?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No, the CO2 indicator solution is not included with this glass drop checker.
