The function of the liquid CO₂ Level Indicator Reagent is to put it into the CO₂ Level Indicator Reagent glass container, which is then installed inside the aquarium. We can then determine whether the CO₂ levels in the aquarium are sufficient based on the different colors displayed by the CO₂ Level Indicator Reagent

The glass aquarium water CO₂ drop checker container is made of glass with an air-sealed design that prevents the liquid inside from coming into contact with the aquarium water. Its high transparency allows for easy observation of the CO₂ Level Indicator Reagent's color

The 2pcs DIY CO2 reactor bottle caps are compatible with standard carbonated beverage bottles available on the market。The CO2 bubble diffuser stone can let the CO2 bubbles become more small and dissolve more thoroughly in water, promoting healthier aquatic plant growth.

The U-shaped glass tube prevents hoses from wrinkling against the glass walls. The black check valve prevents water from flowing back into the aquarium. The large black clamp is used to isolate the tube for ventilation. The 2-meter-long tube meets the installation requirements for this product set.
