Dirt on the bottom
Food and plant remains and metabolic products form debris on the bottom of the aquarium (sludge). In case of oxygen deficiency in the aquarium there is the risk of putrefaction processes at the bottom caused by the debris. Putrefaction endangers the health of the aquarium inhabitants. It is therefore advisable to clean the bottom regularly.
Connect hose on one end to the stopcock on other end to the gravel cleaner. Use the clip to attach the end with the stopcock to a bucket. The clip prevents the hose slipping out of the bucket. Hold the gravel cleaner into the water and activate it by shaking (no suction by mouth required). Move the gravel cleaner inch by inch through the gravel of the aquarium bottom. Finish by clipping the gravel cleaner to the aquarium rim and close the stopcock.
The small round cross section enables you to clean places which are difficult to reach. The edge at the corner of the gravel cleaner allows you to clean into the aquarium corners. Suction strength can be adjusted with cleaning claw.
Thanks to the built-in protective sieve it is impossible for fish or plants to be sucked in.
