1、[Clean Water Quality] The fish tank ozone generator uses ionization technology to generate ozone to cover and clean the fish tank, decompose nitrite, and restore clear water quality. Create a healthy living environment for fish. 2、[Use Requirements] Ozone machine cannot be used in water, it needs to be used with an air pump, and the hose can be connected. It is recommended to place it 7.8in above the level of the fish tank to avoid water backflow. 3、[Efficient] Ozonizer releases a high concentration of active oxygen every minute, and actively decomposes harmful substances such as odor formaldehyde nitrite. Clean pollutants from the source, decompose and reduce to oxygen. 4、[Continuous Use] Aquarium ozone generator can be used continuously, if the water is clear, it can be turned off, and turned on again when the water quality deteriorates. Continue to maintain the water quality in the tank. 5、[Ventilation Use] It is recommended to use ozonizer for ventilation, adjust according to the water quality, the water difference is adjusted to the maximum value on the right, and the water quality is generally adjusted to the middle value of 5.
