1. Disconnect the power supply of the precision filter when taking out the precision filter from the water or doing any maintenance.
2. Frequent cleaning/replacement of filter cotton and activated carbon is a necessary condition to ensure effective filtration: the filter cotton can be removed by opening the bottom cover for cleaning or replacement. The plastic box with activated carbon can also be easily drawn out of the other end of the filter cover. The activated carbon in the filter is usually only used once, and it can be cleaned and then used for two to three times and then renewed. It is best to use the used water in the aquarium or lukewarm tap water to wash the filter material to protect the beneficial bacteria in the precision filter.
