1. ADVANCED TECHNOLOGY: Fish tank generator uses ionisation technology to clean the fish tank cover, break down nitrites, and restore clarity to the water. 2. CONNECTION TO AIR PUMP: Aquarium generator cannot be used directly in water; it must be used with an air pump. A hose connection is sufficient. 3. DECONTAMINATION: Fish tank air water ozonator releases high concentrations of active oxygen every minute, actively decomposing odors, formaldehyde, nitrite, and other harmful substances, helping to reduce pollutants. 4. EASY TO USE: Aquarium generator can be used continuously. It can be turned off when the water is clear and restarted if water quality deteriorates. 5. NOTE: Aquarium generator helps maintain water quality in the tank. Ventilation is recommended, and usage can be adjusted according to water conditions. ADJUSTABLE: Water quality is generally adjusted to a middle value of 5. To prevent backflow, it is recommended to place the ozonator 7.9 inches above the tank level.
