1. Clean and remove dust before use, otherwise these black dust may temporarily affect the cleanliness of water quality. However, it is recommended not to use fresh tap water for washing directly, because Activated carbon Once absorbed by a large amount of tap water, the water quality will be damaged when it is subsequently placed in the filter for use.

2. It is impossible to clean the sundries blocked in the pores of activated carbon by simple cleaning at ordinary times. Therefore, the activated carbon must be replaced regularly to prevent it from losing efficacy due to "adsorption saturation". It is better not to wait for it to become invalid before replacing it, so as to ensure that the activated carbon can continuously remove harmful substances in the water quality of the aquarium. It is recommended to replace the activated carbon 1-2 times a month.

3. The water quality treatment efficiency of activated carbon is related to its treatment amount, which is usually "the effect of water quality treatment is relatively good with more amount".

4. After the quantitative activated carbon is used, the change of water quality should be frequently observed at the beginning of use, and the observation results should be paid attention to as a basis for judging how long the activated carbon will be replaced due to failure.

5. When using the medicine for treating fish disease, the activated carbon should be taken out temporarily and the use should be suspended. To prevent drugs from being activated carbon adsorption And reduce the therapeutic effect.
